[android-developers] Periodic Sync not working.

['Marc Tigges' via Android Developers]

Im using SyncAdapter for some server client synchronization. In the official 
developer guide 
 
it 
is mentioned that there are different methods to trigger a sync.

*1 Run the Sync Adapter When Server Data Changes*

You simply call:

ContentResolver.requestSync(ACCOUNT, AUTHORITY, null);

When server data changes (on GCM for example).

*2 Run the Sync Adapter When Content Provider Data Changes*

Simply use a ContentObserver

public class TableObserver extends ContentObserver {
@Override
public void onChange(boolean selfChange) {
onChange(selfChange, null);
}
   
@Override
public void onChange(boolean selfChange, Uri changeUri) {
ContentResolver.requestSync(ACCOUNT, AUTHORITY, null);
}
}

*3 Run the Sync Adapter After a Network Message*

Do the following:

ContentResolver.setSyncAutomatically(ACCOUNT, AUTHORITY, true)

Now everytime when there is an open TCP/IP connection the SyncAdapter is 
triggered to perform the sync.

*4 Run the Sync Adapter Periodically*

This is for me the important and interesting part. For that you simply have 
to do this (at least this is written in the developers guide):

public static final long SECONDS_PER_MINUTE = 60L;
public static final long SYNC_INTERVAL_IN_MINUTES = 60L;
public static final long SYNC_INTERVAL = SYNC_INTERVAL_IN_MINUTES * 
SECONDS_PER_MINUTE;

ContentResolver.addPeriodicSync(
ACCOUNT,
AUTHORITY,
Bundle.EMPTY,
SYNC_INTERVAL);

*Now to the problem*

Solution 1, 2 and 3 are working perfectly as they should. The periodical 
sync does not. If i just do what is descriped under point 4 the 
synchronization is never triggered (yes i did enable the auomatic 
synchronisation in the system settings of my android device). 

If i do the following:

ContentResolver.setIsSyncable(account, ContentProviderMeasure.AUTHORITY, 1);
ContentResolver.setSyncAutomatically(account, ContentProviderMeasure.
AUTHORITY, true);
ContentResolver.addPeriodicSync(account, ContentProviderMeasure.AUTHORITY, 
new Bundle(), 3600);


The SyncAdapter sync refresh is called every minute (it should be every 
hour / 3600 seconds = 1 hour). If i do the following:

ContentResolver.setIsSyncable(account, ContentProviderMeasure.AUTHORITY, 1);
ContentResolver.addPeriodicSync(account, ContentProviderMeasure.AUTHORITY, 
new Bundle(), 3600);

The sync is only triggered once at creation time and after that never 
again. Yes, as i mentioned already, the automatic sync in the android 
devices settings is enabled.
Triggering the sync manually for my app in the android device settings 
accountmanager is working fine. 

*So why does the periodic sync does not work?*

I tested on Nexus 4 with Android 6.0, On Galaxy Ace with Android 4.4 and on 
Galaxy S3 Mini with Android 4.1. All devices are not syncing periodically.
I also posted my question on 
Stackoverflow: 
http://stackoverflow.com/questions/35879056/sync-not-triggered-as-mentioned-in-developer-guide

[android-developers] In App Purchase Woes

[Marc Call]

Hello everyone,
I have searched the googles many a day and cannot find a solution to my 
problem. I am trying to implement in app purchase in my android app.

Here is what I have done thus far:
I have included com.android.vending.BILLING in my manifest
I have uploaded a signed version of my APK
I have set my app to Active in google play dashboard
I have created an IAP item and published it in the google play dashboard
I have added a few test users in google play to test my own IAP products

Now I know that I as the developer cannot successfully do a purchase with 
my own developer email account but here is the error I get in case it is of 
any use:Your order could not be processed. Please try again

Now when I have one of the test users that I added to be a test account try 
the in app purchase, they receiver the error message Item Unavailable: The 
item that you requested is not available for purchase

I have no idea where to go from here or what to look at, can anyone please 
post any thoughts or ideas? I have been stuck on this for a few weeks now. 
thanks in advance.

Marc

[android-developers] ACTION_SET_ALARM Intent seems too simple

[Marc McDougall]

 

I am attempting to write an application that automatically sets the Android 
default alarm based on some preset values determined by an alternate 
algorithm.

The alarm setting works fine using the ACTION_SET_ALARM intent, however 
every time I run the app, it sets a NEW alarm. I'm wondering if there is 
any way to instead have one unique alarm set to update every time the 
activity sets the alarm (so that there are not hundreds of new alarms in 
the Android alarm application).

I will provide code excerpts if necessary, however it seems that this 
question can be answered without specific examples. NOTE: I am not using 
the Android alarm system that is intended for informing other activities of 
certain events, but rather the actual Android alarm that users will utilize 
to wake up in the morning.

Here is a code snippet that explains what I am doing:

Intent intent = new Intent(AlarmClock.ACTION_SET_ALARM);
intent.putExtra(AlarmClock.EXTRA_HOUR, time.getCurrentHour());
intent.putExtra(AlarmClock.EXTRA_MINUTES, time.getCurrentMinute());
intent.putExtra(AlarmClock.EXTRA_SKIP_UI, true);
startActivity(intent);

Thank you in advance for any assistance!

Some further attempts:

I have tried to bundle the intent Intent.ACTION_EDIT with my intent and 
tried to specify the alarm local to the device, but I can't seem to find 
any documentation on how one would do this. Nor do I know that this is the 
way to complete my goal.

[android-developers] Loading and Saving Settings to a file

[John-Marc Desmarais]

Hi,

I'm not sure what I'm doing wrong here:

I have an Override on onPause to save settings to a file and an
Override on onResume, and onCreate to load them back up from the file.

The onPause method looks like this:
@Override
public void onPause()
{
super.onPause();

// save configuration settings
if (cfg != null)
{
byte[] settingsBuffer = 
cfg.toSerializedBytes(getBaseContext());
Log.v(LogName.onPause, LogName.onPause + : settings 
Buffer :  +
settingsBuffer.length);
try
{
FileOutputStream fos = 
openFileOutput(settingsFile,
getBaseContext().MODE_WORLD_READABLE);
fos.write(settingsBuffer);
fos.getFD().sync();

fos.close();
}
catch (FileNotFoundException e)
{
Log.e(LogName.onPause, LogName.onPause + : 
File not found.  +
e.getMessage());
}
catch (IOException e)
{
Log.e(LogName.onPause, LogName.onPause + : IO 
Error.  + e.getMessage());
}
}
}

The load method looks like this:
public void loadSettings()
{
File inputFile = new File(settingsFile);
if (inputFile.exists())
{
byte[] settingsBuffer = new byte[(int) 
(inputFile.length())];
try
{
FileInputStream fis = 
openFileInput(settingsFile);
fis.read(settingsBuffer);
cfg = 
RXConfigurationSettings.fromSerializedBytes(settingsBuffer);
if (cfg != null)
{
cfg.populateTable((TableLayout)
findViewById(R.id.tableLayoutConfigurationSettingsTable),
getBaseContext());
}
fis.close();
}
catch (FileNotFoundException e)
{
Log.e(LogName.onResume, LogName.onResume + : 
File not found.  +
e.getMessage());
}
catch (IOException e)
{
Log.e(LogName.onResume, LogName.onResume + : 
IO Error.  + e.getMessage());
}
}
else
{
Log.e(LogName.className, Input FILE not found.);
}
}


The loadSettings is called from onCreate and onResume but I seem to
always hit the else condition and logcat always shows Input FILE not
found..

Can anyone provide insight into this problem?

Thanks

Re: [android-developers] Loading and Saving Settings to a file

Hi,

Thank you for your reply. I have a couple follow up comments/questions
related to the responses. I have included these inline.

 Why not just use SharedPreferences?

I felt it would be quicker to serialize my class into a byte stream
than saving each configuration parameter separately and I couldn't
find the ability to store a byte stream using SharedPreferences.

 When you check the file existing, you use the raw file name, not relative
 to your data directory. Of course, that does not exist, as the file is
 relative to your data directory.

 Your subsequent call to openFileInput would likely succeed.

How do I handle the
byte[] settingsBuffer = new byte[(int) inputFile.length];
without opening a File?

i.e. How would I figure out in advance the size of the byte buffer I
need to receive my file? Or, what path can I append to my open file to
allow it to find the settingsFile, or is it not that easy?

 You get the stream of data as the returned value of openFileInput. Then you
 can then read that into a byte array of the input's length. So your settings
 buffer would be initialized AFTER you open the input stream, using the
 stream's length.

Hi

Based on your first response I have tried the following:
public void onPause()
{
super.onPause();
// save configuration settings
SharedPreferences.Editor settingsEditor =
getSharedPreferences(settingsFile, 0).edit();
settingsEditor.putString(RXConfigurationSettings,
Base64.encodeToString(cfg.toSerializedBytes(getBaseContext()),
Base64.DEFAULT));
}

public void loadSettings()
{
SharedPreferences settings = getSharedPreferences(settingsFile, 
0);
if (settings.contains(RXConfiguration))
{
cfg = 
RXConfigurationSettings.fromSerializedBytes(Base64.decode(settings.getString(RXConfigurationSettings,
), Base64.DEFAULT));
}

else
{
Log.e(LogName.className, Input settings not found.);
}
}
And am now getting Input settings not found when closing and
reopening my application.

It seems to me like the tag you are using to put your array into
extras is different from the tag you are using when retrieving it.

How about:
double [] myfinal=extras.getDoubleArray(finals);

[android-developers] Tethering two android phones

[John-Marc Desmarais]

Hi,

Does anyone know of a method to tether two phones via USB so that one
phone can communicate with the other using an intermediate PC?

Or, a method to change the default gateway given when tethering on one
of the phones from 192.168.42.129 to something else.

It seems that if I connect two android phones to the PC both are given
the same gateway address, it is possible to send/receive data from one
phone to the other? is there an address on the other side of the
gateway address that can be used? Can I configure the address on one
of the phones so that the gateway addresses are unique?

Thanks,
John-Marc Desmarais

Re: [android-developers] VideoView and buffering

Hi,

I'm using the reset() now. There's a little bump in the playback every
time it reaches the end of the content that existed in the file when
it was initially loaded which I don't like but I'm using prepareAsync
so I think this hiccup is as small as I can make it with a single
VideoView.

 They actually create new MediaPlayer object upon every update to the

 I would test calling MediaPlayer.reset() first instead of creating new

 Hi,

 I am currently writing a video file to the SDCard while playing it

 My problem is that, if I buffer 1MB of video and begin the Video

 this time, 5MBs of file has now been written to the sdcard.

 I have been trying various things in onCompletion handler.. such as:
                int curLoc = mp.getCurrentPosition();
                Log.e(LogName.onCompletion, LogName.onCompletion + 
 CurrentLocation:

                mp.prepareAsync();
                mp.start();
                mp.seekTo(curLoc);

 In this case I get a Cannot play video message.

 Or:
                int curLoc = mp.getCurrentPosition();
                Log.e(LogName.onCompletion, LogName.onCompletion +

                mp.prepareAsync();
                mp.start();
                mp.seekTo(curLoc);

 This crashes with prepare Async in State 128.

 Has anyone solved the problem of re-queuing file in the videoView so
 that it plays everything that has been written to the sdcard even
 though it starts with a smaller file?

Re: [android-developers] VideoView and buffering

[John-Marc Desmarais]

Daniel,

It is my feeling that since the swap is being done in the onCompletion
handler, there would be a gap in playback in either case. If prepare
is the time consuming part of Prepare(), Start(), Seekto().. then I
can see this shrinking the gap. But, if there is a detectable delay,
then the length of this delay is of lesser concern. If I get the time
to go back to this component when I'm done some other bits, I'll let
you know how it turns out.

I find it odd that the VideoView screen doesn't ever re-read from the
file. I've tried buffering 1MB or 2MB before starting to play, but it
still doesn't go back to the file to read more data, I'm guessing it
loads all 2MB into memory before starting to play. I'll try some
bigger buffer sizes as well to see if I can force it to reread before
the video runs out.

 John-Marc,

 I am glad that it works.

 I am not sure whether prepareAsync would be quicker than blocking prepare 
 call.

 I mean that whatever the system implementation of the player,
 preparing it takes the same amount of time and async call simply does
 not block, but if you call play as a next statement after
 prepareAsync, I think playing will be put on hold until the player is
 ready to play. You could test both approaches by adding some logging
 and swapping these calls to prepare.

 I was also thinking that you could create 2 MediaPlayer objects and
 the one that is not playing at the moment is being prepared in the
 background with the new data that arrived.
 In MediaPlayer.OnCompletionListener of the first player you simply
 cause the background, prepared player to swap seats with the one that
 just finished. Maybe that would be a bit smoother... ( I am only
 speculating here). This is simple double buffering used all over
 computers to avoid flickering when displaying moving objects.

 Not the easiest approach, but if you are swapping the files from
 underneath 1 player, then swapping players from underneath 1 activity
 should not be much more complex.

[android-developers] VideoView and buffering

[John-Marc Desmarais]

Hi,

I am currently writing a video file to the SDCard while playing it
with VideoView.

My problem is that, if I buffer 1MB of video and begin the Video
playback, the video stops after 1MB has been played, even though by
this time, 5MBs of file has now been written to the sdcard.

I have been trying various things in onCompletion handler.. such as:
int curLoc = mp.getCurrentPosition();
Log.e(LogName.onCompletion, LogName.onCompletion + 
CurrentLocation:
 + mp.getCurrentPosition());
Log.e(LogName.onCompletion, LogName.onCompletion + Duration:  
+
mp.getDuration());
mp.pause();
mp.prepareAsync();
mp.start();
mp.seekTo(curLoc);

In this case I get a Cannot play video message.

Or:
int curLoc = mp.getCurrentPosition();
Log.e(LogName.onCompletion, LogName.onCompletion + 
CurrentLocation:
 + mp.getCurrentPosition());
Log.e(LogName.onCompletion, LogName.onCompletion + Duration:  
+
mp.getDuration());
mp.prepareAsync();
mp.start();
mp.seekTo(curLoc);

This crashes with prepare Async in State 128.

Has anyone solved the problem of re-queuing file in the videoView so
that it plays everything that has been written to the sdcard even
though it starts with a smaller file?

Regards,
-jm

[android-developers] VideoView.setLayoutParams - ClassCastException

[John-Marc Desmarais]

Hi,

I have a VideoView in a LinearLayout with 2 other boxes. In trying to
create a full screen video, I am doing the following:

private boolean isFullScreen = false;
public void onClick(View v)
{
VideoView vv = (VideoView) v.findViewById(R.id.videoView1);
LinearLayout.LayoutParams lp =
(LinearLayout.LayoutParams)vv.getLayoutParams();
if (isFullScreen)
{
isFullScreen = false;
lp.weight = 0.2f;
vv.setLayoutParams(lp);
v.invalidate();
}
else
{
isFullScreen = true;
lp.weight = 0f;
vv.setLayoutParams(lp);
v.invalidate();
}
Log.v(LogName.onClick, Video switch to  + (isFullScreen ? 
Full
screen : Normal size));
}

I am getting an exception:

Can anyone suggest why this is the case? Alternatively, can you
suggest another method to set the video view to full screen?

[android-developers] AsyncTask never calls onProgressUpdate

[John-Marc Desmarais]

Hi,

I have the following AsynchTask class but, it fails to execute the
onProgressUpdate method when doInBackground is running. That is to say
the Log.v(LogName.onProgressUpdate, LogName.onProgressUpdate) never
occurs in LogCat. There are two calls to publishProgress. The first is
after the authentication text view is copied to the instance variable
and second in the update thread.

Can anyone offer insight?

public class AuthenticateTask extends AsyncTaskDialog, Void, Boolean
{

private int num_dots;
private boolean firstRun;
private String textToUpdate;
TextView textViewAuthenticating;
Dialog dialog;

private class LogName
{
public static final String className = AuthenticateTask;
public static final String onPreExecute = className + 
.onPreExecute():;
public static final String doInBackground = className +
.doInBackground(Dialog...):;
public static final String onProgressUpdate = className +
.onProgressUpdate():;
public static final String onPostExecute = className +
.onPostExecute(Boolean):;
}

protected void onPreExecute()
{
Log.v(LogName.onPreExecute, LogName.onPreExecute);
num_dots = 0;
firstRun = true;
}

@Override
protected Boolean doInBackground(Dialog... params)
{
Log.v(LogName.doInBackground, LogName.doInBackground);
dialog = params[0];
textViewAuthenticating = (TextView)
dialog.findViewById(R.id.TextViewAuthentication);
publishProgress();
Log.v(LogName.doInBackground, LogName.doInBackground + dialog: 
 + dialog);

Thread updaterThread = new Thread(new Runnable()
{

public void run()
{
// TODO Auto-generated method stub
try
{
Thread.sleep(250);
}
catch (InterruptedException e)
{
}
finally
{
AuthenticateTask.this.publishProgress();
}
}

});

updaterThread.start();
if (Authenticate())
{
return true;
}
return false;
}

protected void onProgressUpdate()
{
Log.v(LogName.onProgressUpdate, LogName.onProgressUpdate);
String tmpString;
dialog.setContentView(R.layout.connnection_progess_dialog);

if (firstRun)
{
Log.v(LogName.onProgressUpdate, 
LogName.onProgressUpdate + First Run);
textToUpdate = 
textViewAuthenticating.getText().toString();
Log.v(LogName.onProgressUpdate, 
LogName.onProgressUpdate +
textToUpdate =  + textToUpdate);
firstRun = false;
}
if (num_dots++ == 5)
{
num_dots = 0;
}
tmpString = textToUpdate;
for (int i = 0; i  num_dots; i++)
{
tmpString +=  .;
}
Log.v(LogName.onProgressUpdate, LogName.onProgressUpdate +
tmpString =  + tmpString);
textViewAuthenticating.setText(tmpString);
}
protected void onPostExecute(Boolean result)
{
Log.v(LogName.onPostExecute, LogName.onPostExecute);
String authentication_finished =
dialog.getContext().getResources().getString(R.string.authentication_finished);
Log.v(LogName.onPostExecute, LogName.onPostExecute + 
authentication_finished);
textViewAuthenticating.setText(authentication_finished);

textViewAuthenticating.setCompoundDrawables(dialog.getContext().getResources().getDrawable(R.drawable.checkmark),
null, null, null);
firstRun = true;
}

}

Re: [android-developers] Re: AsyncTask never calls onProgressUpdate

[John-Marc Desmarais]

Hi,

The authenticate method takes a long time, and I want to update
progress while that's happening like this:

Authenticating .
Authenticating . .
Authenticating . . .
Authenticating . . . .
Authenticating

So I created a thread to add a dot to my TextView every 1/4 second.

Mark Murphy's solution seems to be functioning properly. My error was
assuming that
protected void onProgressUpdate() was equivalent to
protected void onProgressUpdate(Void... voids)
as well as missing some @Overrides.

Thanks all,
-jm

[android-developers] Add Native Support not found in Eclipse

[John-Marc Desmarais]

Hi,

Can anyone help getting Android Tools - Add Native Support to show up
in Eclipse?

Eclipse Version:
Eclipse IDE for C/C++ Developers

Version: Indigo Service Release 1
Build id: 20110916-0149

My system path includes
C:\Android\android-ndk-r7

Running Windows 7.

I have no problems building Android apps, but I want to add some native support.

Re: [android-developers] Re: Add Native Support not found in Eclipse

[John-Marc Desmarais]

Hi,

Thanks for your help. I installed Sequoya and MTJ but, I still have no
Add Native Support under Android Tools.

I have also tried installing android-ndk-r6b and having
C:\android\android-ndk-r6b in the path. But, currently, I have
C:\android\android-ndk-r7 installed and in the system path.

Maybe Indigo is the problem. I'll try Helios.

Have you been able to solve this issue?
I'm having the same issue right now.
I don't find a matching android:name so I don't think that's the solution.

I want to create two apk's, one supporting openGL 2:0 (having a higher 
version) and a second one for the others.
But the android market says that both apk's support the same set of devices.

Re: [android-developers] Re: How to detect if a view is on screen

[Marc Van Daele]

Hello Ed,

Thanks for your answer but I'm not sure a ListView will work (though I will
look at the video).
Isn't a ListView limited to Vertical scrolling? (at least the javadoc says
so)

Kind Regards,

Marc



2011/9/6 Ed edscha...@gmail.com

 Hi Marc,

 Have a look at ListView. It's probably done most of the hardwork for you if
 you just write your own adapter. Just make sure you get your getView
 correct.

 Watch a couple of Romain Guy's videos from Google I/O e.g.
 http://www.youtube.com/watch?v=wDBM6wVEO70

 Should help get you started in the right direction.

 Cheers,

 Ed

Re: [android-developers] Re: How to detect if a view is on screen

[Marc Van Daele]

In fact, I'm using HorizontalScrollView already
but I'm worried about memory consumption (I'm coming from the embedded
software world)

Inside the HorizontalScrollView  I have a LinearLayout containing a list of
my own Views
(actually a ViewGroup displaying a movie poster but also information on the
actors, description, icons for parental rating etc).

Whenever my View is first loaded (first dispatchDraw call), I load the
Bitmap for the movie poster.
But right now, I never unload this bitmap so I'm worried about memory usage.

Hence I want to release the Bitmap when the View is not on screen.
I don't think HorizontalScrollView as such (nor ListView) provides support
for this (please correct me if I'm wrong)

I looked a bit in the source code of HorizontalScrollView and noticed that
it has a private :-(  method isOffScreen(..).
Based on that code I now do something like (in the parents dispatchDraw)

 ViewGroup scroller = (ViewGroup)
getChildAt(0);//HorizontalScrollView
ViewGroup layout = (ViewGroup) scroller.getChildAt(0);//LinearLayout
for (int i = 0; i  layout.getChildCount(); i++)
{
View child = layout.getChildAt(i);
//check if an asset/event is visible
if(isOffScreenHorizontal(scroller, child))

 //call unload method
}
}

with isOffScreenHorizontal
private boolean isOffScreenHorizontal(ViewGroup parent, View child)
{
Rect mTempRect = new Rect();
child.getDrawingRect(mTempRect);
parent.offsetDescendantRectToMyCoords(child, mTempRect);

return !((mTempRect.right) = parent.getScrollX()

}

Can you give feedback on this approach?

 Hah, I should have thought of this name! 'HorizontalScrollView' has
 been supported since API level 3, and it sounds like just what you
 want.

Hi Marc,
 
Have a look at ListView. It's probably done most of the hardwork for
 you if
you just write your own adapter. Just make sure you get your getView
correct.
 
Watch a couple of Romain Guy's videos from Google I/O e.g.
   http://www.youtube.com/watch?v=wDBM6wVEO70
 
Should help get you started in the right direction.
 
Cheers,
 
Ed

[android-developers] Re: How to detect if a view is on screen

[Marc Van Daele]

I didn't see my question (see below) appear in the group yet so I'm
resending.
Sorry if it appears twice.

Marc

2011/9/3 vdaele marc.van.dael...@gmail.com

 Hello,

 Suppose I have a horizontal scrollable list of say 100 movie posters
 (each in its own View)
 of which only 4 Views fit on the screen at the same time.
 When I've scrolled through the complete list once, I will have 100
 Bitmaps in memory of which only 4 are visible.

 To save memory, I want to release the Bitmaps of those Views that are
 off-screen.
 Is there an easy way to know whether a View is effectively visible or
 should I compute this myself?

 (I've looked at the onVisibilityChanged listener but this seems to
 serve a different purpose)

 Thanks for your help,

 Marc

[android-developers] Extend SlidingDrawer, add header view

[Marc]

Hi,

I'm looking to customise the sliding drawer as well as add an extra
view, however the slidingdrawer class seems to only allow the handle
and content views to be nested inside the sliding drawer (I would like
to add a header that sits to the left of the handle (don't want this
to be nested inside handle as it cant have touch events)).

I have been able to customise the handle by overriding the layout of
the handle using the onlayout method, (i pushed the handle to align
with the right of the screen) and would like to create a header that
sits to the left of this.

 I am not placing this header inside the handle as i dont want to
modify the handles touch events and i would like the header view to be
a view, and not have any touch events at all, just follow along next
to the handle.

 Any ideas on how i would do this? i am currently using a class that
extends slidingdrawer and overiding layouts etc there at the moment

  You can get an idea of what a rank for an app is by going into the
 market,
  selecting all apps and start counting, manually, until you find the app

 beyond
  about 800 in overall rank as that's the maximum (or used to be) number
  listed in the all category.

[android-developers] Start an external activity from a BroadcastReceiver

[Marc]

Hello folks,

after googling all the day, I have solution to actually start an
external activity from a receiver.
In the end I added a service to the package, so the receiver starts
the service and the service should start the activity. Of course that
doesn't sound very efficient at all, but in addition to this it
doesn't work either. Thats my code from the service:

public void onCreate() {
super.onCreate();
Intent i = new Intent(android.intent.action.MAIN);
ComponentName n = new
ComponentName(com.schwimmer.android.carmode,
com.schwimmer.android.carmode.ToggleCarMode);
i.setComponent(n);
i.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
getApplication().startActivity(i);
//this.stopSelf();

If I put this code into an activity and start it wit
this.startActivity() it works like a charm. But not if it is put into
the receiver or server.

Do you have any idea how to fix that?

Thanks!
Marc

[android-developers] Invisible Activity

[Marc]

Hey,

I would like to create an app that changes the volume and then exits.
For that I obviously won't need an UI or service, as a toast is
enough.

So how exactly do I write an invisible activity? I tried
android:visiblity=gone in the Android Manifest, that that didn't
work.

I guess that's a noobish problem, but I started programming with
Android just a couple of days ago ;)

Thanks!

Re: [android-developers] Usage Statistics

monitors all the application resume/pause state and logs into files.

and check how the settings app is using it here:

[android-developers] Promotional Graphic in PNG gets converted to _very lossy_ JPEG in Android Market?

[Marc Reichelt]

Hi!

I have a problem with the Android Market. I uploaded a promotional
graphic (180w x 120h) as PNG. However, the Android Market seems to
apply a _very_ lossy JPEG compression on it - it just looks ugly.
Here is the image I uploaded to the Android Market:
  http://marcreichelt.de/misc/nichtlustig/before.png
It gets converted to this PNG image (which basically is a JPEG image,
but with .png extension):
  http://marcreichelt.de/misc/nichtlustig/after.png

Is this a bug in the Android Market, or am I doing something wrong? I
even tried to upload a JPEG image with not so high compression or as a
PNG image with an optimized 256 color palette (which is even smaller
than the resulting JPEG file of the market) - but he is still screwing
up the image. :-/


Thanks for your help  regards

[android-developers] In-app billing does not work - although everything has been checked

[Marc Reichelt]

Hi!

I am including In-app billing in a new Android application I am
currently working on. The project is nearly finished and it should go
live as soon as in-app billing goes live.

In this project I want that users can donate to support the
application. However, I can not get In-app billing to work, although I
think I did everything right. Every time it is showing me that the
product is unavailable. Here is the logcat shortly after clicking the
button to purchase the item (product ID donate_1) and after closing
the Android Market dialog:
03-26 12:07:42.440: DEBUG/More(12297): buying: donate_1
03-26 12:07:42.440: DEBUG/BillingService(12297): RequestPurchase

from pid -1
03-26 12:07:42.770: INFO/ActivityManager(96): Displayed
com.android.vending/.billing.InAppBuyPageActivity: +313ms
device shows market dialog that product is unavailable.
03-26 12:12:28.500: INFO/BillingService(12297): handleCommand()

RESULT_ITEM_UNAVAILABLE
03-26 12:12:28.500: INFO/More(12297): purchase failed

This is what I checked:
1) I correctly signed and uploaded my APK file to the developer
console and saved it as draft, and I installed it on my real device.
2) I ensured that my test account, e.g. example_t...@googlemail.com,
is listed as test account (the developer account is a different one,
let's say example_...@googlemail.com) and is the primary account on my
device.
3) The product donate_1 (unmanaged because multiple donations should
be possible) is listed as published and has a price of 0.79 €.
4) All static responses triggered by android.test.purchased etc.
have been tested and work.
5) Of course the Android Market is checked to have the latest version
(2.3.4).

So I believe I checked all points from
http://developer.android.com/guide/market/billing/billing_testing.html#billing-testing-real
- and I have no idea why it still does not work. Maybe a bug? It
wouldn't be the first time that ...@googlemail.com addresses make
problems, but ...@gmail.com do not. But that is just my guess.

Hi Kostya,

did you publish the In-app-items? Testing In-app payment will not work
if you do not publish the In-app-items. You don't have to publish your
app for testing it. In fact, you can not publish an application using
In-app billing right now.
My problem just is that I did everything the documentation says and
still can not test it successfully.

 I am also getting ITEM_UNAVAILABLE for my own product item with both a
 test account and my developer's account. The application is uploaded but
 not published, and so it the item.

 In addition, purchasing authorization for android.test* items under
 the test account never completes.

 FWIW, the product list editing page says this:

 An in-app product will appear UNPUBLISHED until the owning application
 is PUBLISHED, at which point the in-app product's publishing state
 applies. Please use the application editor to modify the application's
 publishing state.

 Not sure what this means for testing. Also, the License Test Response
 field in the profile page (where you set up test accounts) doesn't
 appear to have any codes specific to in-app billing, just codes for LVL.

Hi Kostya,

of course they did charge your account for real - you _definitely_
should read the In-app documentation before doing anything else!
And as I pointed out I am using a correctly signed release build, not
the debug build. Still having problems.

 Ah. Good point, thanks.

 Just published my test item, and tried to purchase it from the
 development phone.

 It short, it worked.

 However, even though my development phone is listed as a test account in
 the Developer Console profile, I still had to enter a real credit card
 number (no VISA--FAKE there), and they charged my card for real.
 Good thing I set the price to $0.99.

 After I submitted the purchase, the Checkout window didn't go away for a
 long time, then I got an error report in the logcat about the billing
 activity having leaked a window. A couple of minutes later the
 application showed that the item state changed to PURCHASED.

 Oh, I am using the actual release build, signed with a non-debug key,
 same .apk as I uploaded to Market. Are you perhaps using a debug build
 on your phone?

[android-developers] Re: In-app billing does not work - although everything has been checked

[Marc Reichelt]

Hi Kostya,

by the way: you can refund the payment you made from your Google
Merchant account.
Remember that you are testing the real system there, which means real
money is going to flow if you do not refund it shortly after.

  In-app billing right now.

 Ah. Good point, thanks.

 Just published my test item, and tried to purchase it from the
 development phone.

 It short, it worked.

 However, even though my development phone is listed as a test account in
 the Developer Console profile, I still had to enter a real credit card
 number (no VISA--FAKE there), and they charged my card for real.
 Good thing I set the price to $0.99.

 After I submitted the purchase, the Checkout window didn't go away for a
 long time, then I got an error report in the logcat about the billing
 activity having leaked a window. A couple of minutes later the
 application showed that the item state changed to PURCHASED.

 Oh, I am using the actual release build, signed with a non-debug key,
 same .apk as I uploaded to Market. Are you perhaps using a debug build
 on your phone?

 -- Kostya

  My problem just is that I did everything the documentation says and
  still can not test it successfully.

[Marc Reichelt]

OK, I solved it - it really was a @googlemail.com / @gmail.com
problem.
I entered the corresponding @gmail.com address as test account, and In-
app billing started to work. It seems to be an issue at Google, so I
entered a new issue here: 
http://code.google.com/p/marketbilling/issues/detail?id=4
I hope they will catch up and solve this problem before In-app billing
goes live - although it should only affect some users (e.g. Germany).
IMHO they really should stop to allow these @googlemail.com accounts.

 Why the of course? I set this phone up as a test account in the Market
 console, and the system knows this.

    - you_definitely_
  should read the In-app documentation before doing anything

 Yes, definitely plan to, when I actually start implementing it in my
 app. So far I've only had time for a first, cursory read.

 Anyway, it was only $0.99, less than half the price of a pack of
 cigarettes. And I can issue a refund to myself.

  And as I pointed out I am using a correctly signed release build, not
  the debug build. Still having problems.

 Weird. From your description, we have identical setups: release builds
 uploaded but not published, installed on the phone, item published in
 the console, Market 2.3.4. And yet it worked for me and didn't work for you.

[android-developers] Scaling on Two Webviews

[Marc Lester Tan]

Hi,

In my application, i need to display 2 webviews inside a linearlayout in
vertical orientation. The code looks something like this on the onCreate
method of my activity:

LinearLayout container = new LinearLayout(this);
container.setOrientation(LinearLayout.VERTICAL);

WebView mWebView = new WebView(this);
WebView mWebView2 = new WebView(this);

mWebView.loadUrl(http://www.google.com;);
mWebView2.loadUrl(http://www.yahoo.com;);

container.addView(mWebView);
container.addView(mWebView2);
setContentView(container);

Now, Webview has built-in scale gesture listener and if I try to scale the
first webview (mWebView), it will scale properly but then when I try to
scale the second one (mWebview2), it doesn't scale at all but it does
receive the touch events. Note that the two webviews are displayed at the
same time on the screen.

Any idea what's going on here or what should I do so that the second webview
will also scale? Is it a bug or a limitation?

[android-developers] Thread + ImageView

[Marc CG]

Hi everybody!

First, sorry if my English is bad, usually i don't use it...

I am making a program witch have 2 java class. The first class is the
main activity and the second is a thread.

In the main activity i have some ImageViews, Textviews, CheckBox and
RadioButtons. My Problem is that when i want to modify the ImageView
from main activity to a new Image (that i have into resources) my
debugger says: Source not found. But if i do this out of the thread
it works.

I can't see the problem!

Thanks for all!

It seems that it is in fact an NXP PN544.  Anyway having a secure element
integrated in the Nexus S would be great news, even if it take some time to be
able to use it.  But knowing that the chip can support a secure element does not
mean that there is one.

 
 Any ideas on how to use this security chip? Eg writing data
 (generating/writing RSA keys or writing symmetric keys) into the chip,
 extracting generated _public_ keys and also use the keys for
 encryption/decryption?
 
 Any ideas on how to do it in Android?

I was not able to find anything in the current AOSP, but I think that a lot of
work would be needed to have this.  First you need the integration of pcsclite,
similar to what seek-for-android did.  But after this someone need to write a
PKCS#11 provider implementation, similar to the SunPKCS11 provider.  I was not
able to find one, either in Apache Harmony or BouncyCastle, so that probably
something that had to be written from scratch.

After this, and assuming that the Nexus S really contains a secure element, any
Android app will be able to store/generate and use RSA/ECC keys in a secure way.

Well, it's a PITA, as you cannot pay by credit card.  I had mine bought by a
German friend of a friend, who was traveling to the US.

Anyway, here's the website:

https://www.cardsolutions-shop.com/shop/gi-de/

 
 Nikolay: In this case, the security is about singulary. The key should
 be copy protected, but it does not need to be use-protected because I
 want to be sure, that if I leave the phone on a table, go on toilet,
 come back and take it back, I can be sure that nobody has access to my
 key, even if they impersonated me in that little brief amount of time
 that I was on toilet for example.
 Having the key stored in software (eg software token or in standard
 phone memory), the key is no longer secure, since if I leave my phone
 out of sight even for a brief amount of time, its possible that
 somebody just copied my key.
 If I store the key in software, I would need to have 100 % of sight of
 the phone all the times, else the key could be regarded as
 compromised.
 
 In other words, if I have the phone in my hand, I should be
 *absolutely* confident in that nobody can authenticate as me.
 
 Another example, I lend my device to my friend for the purpose that my
 friend can log in to my account for a brief time. When I then get the
 device back from my friend, I want to be sure that my friend doesn't
 have a copy of my private key and can log in as me, in case we stop
 being friends and sabotage for me.

 develop for the different OS versions and screen sizes.
 
 Now I understand what you're saying with the emulation but this blanket
 answer is getting kind of old.  Stop giving the 'You can't get there

 emulators route the OpenGL calls to the desktop PC and allow you to
 choose the level of acceleration.  Maybe this is something that can be
 looked into.  Sure I know you're not getting a 1:1 mapping but it does
 allows you to develop.  How about making a new driver backed by the
 desktop GPU and give some way to select it?

And what about you write and contribute this driver to the code base?  There was
something I disliked in the phone emulator, I fixed it for myself, and then
submitted it in Gerrit and the patch was accepted, all in less than two months
and it is now part of Gingerbread.

Complaining about missing features on an open source project is ridiculous.

 At the end of the day, you absolutely need to test and run on a
 device, especially for doing things like OpenGL games.  An emulator or
 simulator on desktop hardware is never going to give you a good idea
 of how your app performs on real hardware.

 This isn't an excuse for the emulator being slow (we really would like
 to improve it, this is just a fairly challenging problem), but no
 matter what is done it can never be a replacement for running on a

I assumed that the OP wanted to use the Android tablet in a professional
environment (inventory, etc...), in which case having an hand held scanner is
mandatory.  A Bluetooth scanner (or a scanner with a serial port and a
Bluetooth/Serial bridge, like the Iogear GBS301), is a good solution in this
case, and writing the Android app should be simple.

[android-developers] Flipping views (or: the magic behind onInterceptTouchEvent)

[Marc Reichelt]

Hi!

I want to create a new widget for Android developers which allows to
use the same functionality as seen on the home screen (flipping
between different screens), the calendar (flipping between days) or
TweetDeck (flipping through Twitter columns). The source for the
launcher is there, so I thought this might not take so long:
http://android.git.kernel.org/?p=platform/packages/apps/Launcher.git;a=blob;f=src/com/android/launcher/Workspace.java;h=2e04311f530003dbd76695f46876a785164acb99;hb=HEAD#l572

It seems that the two methods onInterceptTouchEvent() and
onTouchEvent() do all the things that are needed for getting the
events, so I copied them to a new class and removed functionality that
is for the Workspace only. You can see my work-in-progress here:
http://pastebin.com/8p8GCEZK

My problem now is: onInterceptTouchEvent() is always only called once
with the MotionEvent.ACTION_DOWN action so I never get into the
ACTION_MOVE case - where the actual fling would be initiated. I played
around with the return values of onInterceptTouchEvent() (true means
to steal events from children) and the return values of onTouchEvent()
(true means to consume the event), but I didn't get any further.

Is there some kind of magic behind onInterceptTouchEvent() or
onTouchEvent() which I didn't notice? Is my problem even solveable? I
hope so... :-)


Thanks in advance  merry christmas

[android-developers] Re: Custom checkable view

[Marc Poppleton]

Ok, problem solved after having looked at the source of the
CheckedTextView. I had to override the onCreateDrawableState and
drawableStateChanged methods and it now works.

 In my toogle method I just calls the setChecked method with a boolean

 The background of the FrameLayout is given a StateListDrawable in
 which I've defined a drawable item for the following states :
 state_pressed, state_focused, state_checked=true, state_checked=false.
 When I press my custom view, the background changes all right back and
 forth between the state_pressed=true and state_checked=false items.
 But state_checked=true is never called.

 What am I doing wrong?

 Thank you for your help,

[android-developers] Re: Tomcat on Android

[Marc Fleury]

 I guess if it's a wall
 mounted device, it might be ok.  But at that point why not just use a
 PC of sorts and use some linux distribution and use your app as is,
 why even use Android at all?

You would be surprised how difficult it is to get a decent ARM based
fanless PC with a stable linux and working JVM.  We have been working
on it at www.openremote.org and you can find it but it is hard to do
and then distribution is a headache.  These are part of the reason why
we are looking for an android based server (in the wall). Also I think
the prices will be go down quickly due to economies of scale.  IT then
may be a decent server platform.   But yeah, I got to weight the
difficulty of porting against the joy of an in-wall android.  I got to
admit that porting is complicated and was full of nasty surprises for
me :(.  This is not java, the libraries, this is android-java,
unfortunately a different beast.

[android-developers] Re: Tomcat on Android

[Marc Fleury]

Thanks Jason. Very useful.  i-jetty looks quite interesting run as a
service on android and may just be the ticket.

I may also contact the tjws guy see if he is porting to android.

On A/ this is meant for an in-wall device so no issues of power.

Thanks again.

 Or you could try this:

 Haven't tried it myself, but looks like it's designed to be

 Or.. maybe even better:

 In either case it's likely to be:

 A) A battery killer due to much heavier resource usage than normal

 B) Could be a performance problem if the container itself is

[android-developers] Tomcat on Android

[Marc Fleury]

I have seen other threads on the topic, most notably one asking about
tomcat/jboss on android.

Anyway, I am actually interested in hearing if people have
successfully ported tomcat on android? the use case for me would be
www.openremote.org.  We distribute a controller that is written in
java6.  I have actually started porting parts of it to Android and in
doing so got to thinking we could port the whole thing to android.  As
a dedicated controller in the wall (forget screens and such, this is
not an smart phone) it would be quite killer.

Has anyone succeeded? maybe I haven't searched hard enough?

 Why we want to do like this is:

 I think Google Android will flow the same architecture later on. We
 can reduce porting effort.

  Also there is something misleading in this:

 Currently, GSM and CDMA are supported by Telephony Manager. They are
 the media and VoIP
 is a technology which works over the DATA (GPRS, EDGE, Wifi, WiMax or
 Ethernet).
 Is it correct to integrate the VoIP changes into the Telephony
 Manager?

 I have seen opensource Android VoIP applications completely skip
 Telephony Manager (Framework Layer)
 and develop their applications as follows:

 Application --- Service  Socket  Native C lib

 Application  Native C --- Kernel (FW or Telephony Manager layer
 is skipped)

 Which is the best way to do this?

 Could you please suggest?

[android-developers] Re: Optimizing image processing algorithms for Android

[Marc]

I have spent a lot of time optimizing signal processing algorithms
using both arm assembly and memory optimizations. The memory
optimizations can be huge. I remember one project the speed more than
doubled once we only using cache memory. That is the entire working
data set was less than 8k.

The process is fairly straight forward: Determine the size of your
cache, then use only that much memory. This typically requires doing
tricks like making the output buffer overlap the input buffer.
Basically you need to know exactly where every byte of memory is being
used. Java tends to be allocate as you need memory model, but for
cache optimizations you need tighter control of memory usage.

 Yep, much of our effort on iSeries went into the memory bottleneck
 area.  Eg, we got fairly astounding improvements (ca 20%) when we
 packed objects so that the fields of SubclassOfA filled in the
 holes left from aligning the fields of A.  And even more
 improvement by packing the Char array owned by a String into the
 String and arranging it so that the two shared a single header.

 (BTW, with regard to alignment, note that most processors can handle,
 eg, unaligned ints and longs, but often the storage accesses are
 several times longer if unaligned, so alignment may be very important,
 even if unnecessary.)

   In such cases the most efficient approach is native Java, but I only

[android-developers] Cursor that will work with query for 2 tables

[Marc]

I have a little program that writes to a SQLite database with 4
tables. When I do a query (either with rawQuery or
SQLiteQueryBuilder.query) the cursor only has column's from the first
table. Does anybody know how to do a query on 2 tables that have been
joined on a key value?

some code

public void onCreate(final SQLiteDatabase database) {
String sqlCreate =
CREATE TABLE IF NOT EXISTS Catch (
+ ID integer primary key 
autoincrement,
+ GPSLON  FLOAT, 
+ GPSLAT  FLOAT, 
+ TimeTIMESTAMP, 
+ BaitID  INTEGER, 
+ RigsID  VARCHAR,
+ FishID  VARCHAR,
+ SyncStatus  INTEGER
+ );;
database.execSQL(sqlCreate);

sqlCreate =
CREATE TABLE IF NOT EXISTS bait (
+BaitID integer primary key 
autoincrement,
+SyncStatus  INTEGER,
+BaitNameVARCHAR unique);;
database.execSQL(sqlCreate);

sqlCreate =
CREATE TABLE IF NOT EXISTS rigs (
+RigsID integer primary key 
autoincrement,
+SyncStatus  INTEGER,
+RigsNameVARCHAR);;

database.execSQL(sqlCreate);

sqlCreate =
CREATE TABLE IF NOT EXISTS fishSpecies 
(
+FishID integer primary key 
autoincrement,
+SyncStatus INTEGER,
+FishName   VARCHAR);;
database.execSQL(sqlCreate);
}



private long addBait(final Catch c) {
long id=-1;
Cursor data = db.query(bait,
null,
BaitName = '+c.baitText+',
null,
null,
null,
BaitName DESC);

if (data!=null) {
if (data.moveToFirst()){
id = data.getInt(0);
}
}
data.close();
if (id==-1){
final ContentValues initialValues = new ContentValues();
initialValues.put(BaitName, c.baitText);
initialValues.put(SyncStatus, c.syncStatus);
id = db.insertOrThrow(bait, null, initialValues);
}
return id;
}

public long addCatch(final Catch c) {
long baitId = addBait(c);

final ContentValues initialValues = new ContentValues();
initialValues.put(GPSLON,c.lon);
initialValues.put(GPSLAT, c.lat);
initialValues.put(Time, c.time.toString());
initialValues.put(BaitID, baitId);
initialValues.put(SyncStatus, c.syncStatus);

final long addedRow = db.insertOrThrow(Catch, null,
initialValues);
return addedRow;
}


   public Cursor getAllMyFish() {
SQLiteQueryBuilder builder = new SQLiteQueryBuilder();
builder.setTables(Catch Bait);
Cursor c = builder.query(db, new String[]{}, null, new 
String[]{},
null, null, null);
return c;
}


It is the cursor that is returned from getAllMyFish() that I want to
have fields from both Catch and Bait but I only get fields from Catch
when I look at the values returned from the cursor's getColumnName()

I use this SDK : http://developer.android.com/sdk/index.html
along with 3 different versions of Eclipse, but it's the same error-

NB.: I don't have a .classpath file, nor do I have a .project file.

  Could that cause the problem ?

  Help is greatly appreciated.

  Thanks.

[android-developers] Re: system lock up and restarts when I start and stop my app.

[Marc]

So it seems the problem was memory leaking. I found I was not calling
release() for sound pool, which ultimately solved the problem. But I
may have had other memory leaks as I null'ed out a lot of stuff.

I figured I should post the solution in case someone run in to the
same problem in the future.

 I had a similar situation with one of my apps, not identical but maybe
 close enough to be of help. I eventually tracked it down to a race
 condition between OpenGL and my own code. I fixed it by adding the
 Java volatile modifier to all variables accessed in the onDrawFrame
 handler.

 I don't know if your game uses OpenGL, but if it does, that's
 something to try.

[android-developers] system lock up and restarts when I start and stop my app.

[Marc]

I have this game, which is almost done. It has 1 critical bug. When
the app exits and restarts, the phone goes in to super slow mode and
eventually restarts.

I am at a loss as to how to debug it.

It seems like something is happening to make the program run super
slowly. The 2nd time the program exits it takes a very long time to
exit and when the phone returns to the main screen the program is
almost totally unresponsive. The phone will eventually restart
itself.

Some more information:
  I do not get a restart in the emulator. I can exit and restart the
app in that environment. My phone is a G1.

[android-developers] Placing focusable clickable views in a custom expanded view in the notification bar

[Marc Reichelt]

Hi!

Has anyone tried to put Views, e.g. Buttons, into a list item of the
notification bar?
In my opinion this would be really helpful for actions that should be
accessible in a very fast manner, like activating/deactivating WiFi or
the 3G network. In fact I saw something like this implementet on the
Samsung Galaxy S device, and now I am trying to achieve the same for
all devices.

I created a custom Notification using this guide:
http://developer.android.com/guide/topics/ui/notifiers/notifications.html#CustomExpandedView

Placing two buttons in my own layout was easy. But here is the
problem: The class RemoteViews ( 
http://developer.android.com/reference/android/widget/RemoteViews.html
) has a method called setOnClickPendingIntent(int viewId,
PendingIntent  pendingIntent), but it doesn't seem to work. The
buttons are not focusable nor clickable, only the whole list item as
such is clickable. And when it is clicked the PendingIntent of the
notification is executed, not the PendingIntent of one of my buttons.

Any suggestions?

[android-developers] DialterFilter, what does this widget do?

[Marc Poppleton]

Hi all,

Browsing in the API I've stumbled upon the DialerFilter widget. Since
I can't find much documentation about how to us it, let alone know
what it does, I tried to use it in a little app just to see what comes
out.
I keep getting a IllegalStateException in the Layout builder about the
DialterFilter needing a child EditText named hint. Looking at the
source of the DialterFilter class I can see that the widget is indeed
waiting for a EditText named hint, but not in my R.class but in the
R.android.internal class. So adding a EditText named id+/hint in my
layout XML file won't solve the problem.
So how can I solve this problem? Would it be that DialterFilter is a
private widget that we can't use but happens to be in the API
documentation?
I'm trying to build a clone of the Sense dialer (keypad at the
bottom part of the screen, filtered contact list at the top part of
the screen) and, according to its name, DialterFilter sounds like what
I'm looking for.

Thanks for you help,

Marc

[android-developers] Processing Camera Preview

[Marc Lester Tan]

Hi everybody,

I just want to ask what is the best way to do processing of preview frame from 
the Camera. Right now, I am doing it like this:

1. I put the byte[] from onPreviewFrame to a queue (limited to 10, for this 
example) until the queue is full.
2. ProcessingThread fetches from this queue for processing
3. ProcessingThread post updates to the UIThread for the result of the 
processing.

Is there other way or pattern to do this kind of scenario? Thanks in advance.

Regards,
Marc

[android-developers] Add header/footer to ListView in XML?

[Marc Reichelt]

Hi!

Is it possible to add header or footer views to a ListView by just
defining them in the layout XML code? So without having to inflate the
views and call addFooterView() or addHeaderView() manually?


Thanks in advance

 Try setting focus on the EditText - the soft keyboard pops up automatically
 for me doing that. Note however that this may depend on the platform version
 and whether the device has a physical keyboard or not. Not sure.

[android-developers] Re: How to make the keyboard to show

[Marc]

This works for me, I have a button the user presses and the keyboard
pops up.

final ImageButton abc = (ImageButton)
numbers.findViewById(R.id.ButtonAbc);
abc.setOnClickListener(new View.OnClickListener() {
public void onClick(final View v) {
final InputMethodManager mgr = 
(InputMethodManager) ((Activity)
context)

.getSystemService(Context.INPUT_METHOD_SERVICE);
// only will trigger it if no physical keyboard 
is open
mgr.showSoftInput(edit,
InputMethodManager.SHOW_FORCED);// .SHOW_IMPLICIT)
}
});

I think I tried to do it in onCreate but that did not work, it had to
be done after the dialog or window was fully created, but my memory is
a little hazy.

I have 3 published apps. Yet I recently tried to get someone using a

Can anybody suggest a way for me to determine why and get them listed.

 Do you have Android projects in your workspace that are broken? (ie
 they don't have a valid target?) That would be a reason for the NPE to
 show up.

 We have fixed the error already. I might look into pushing the fix
 sooner than later.

[android-developers] HTML5 video tag improved support

[Marc-André Moreau]

Hi Android developers,

I'm trying to get the HTML5 video tag working on Android 2.1, but I'm a
bit confused about its current level of support. The Android 2.0
highlightshttp://developer.android.com/sdk/android-2.0-highlights.html
say
that Android 2.0 has video tag support in fullscreen mode.. I was able
to get the video to work in very limited conditions, where the Android
browser detects a video element on a page, and allows you to start playing
it in full screen only. That seems to be the only level of support for the
HTML5 video tag so far, which lacks the cool features. I tried various video
players that support the video tag for various platforms, but they all don't
work with the Android browser, because it looks like the browser just
launches the video independently of the browser, with no communication
between the browser and the player, such that you can't seek or retrieve the
current time from the browser properly. html5video.org has a page where it
puts links to various players supporting the video tag:

http://www.html5video.org/demos/

Otherwise here is another very good player supporting the video tag that can
be used for testing purposes:

http://camendesign.com/code/video_for_everybody/test.html

While Chrome appears to have very good HTML5 support, the Android browser
seems to be quite behind. Is improved HTML5 video tag support planned for
the next release of Android? Is anybody currently working on improving it?

Thanks,

- Marc-Andre Moreau

[android-developers] Animating the background of a LinearLayout

[Marc Poppleton]

Hello,

Is there a way of being notified when a TransitionDrawable has
finished its transition?
I'm looking for a way to animate the background of a LinearLayout,
switching it back and forth between two images thus creating a
pulsating effect. TransitionDrawable works nicely, butonce. I
tried stacking several 'item' in the XML defining the transition, but
no luck. It justs fades from item 1 to item 2 and sits there.
I'm wondering if I shouldn't implement a custom Animation.

Any ideas?

Thanks :)

FYI : target platform is 1.5

 yes, TransitionDrawable fades in/out two Drawables and you cannot make
 it work in repeat mode

  I'm wondering if I shouldn't implement a custom Animation.

 i would implement custom Drawable instead



  Any ideas?

[android-developers] Re: memory problem with image... but strange...

[Marc Reichelt]

Hi Kofa,

I guess you have a memory leak here. Please make sure that all your
data is cleaned up, i.e. no hard references are left.
Try to call the GC manually and see how much it cleans up.

Tip: Override the finalize() method of your activity and print out a
log message there to see if the activity really is cleaned up later.

[android-developers] Maintaining a free and paid version maybe other version

[Marc]

I used to be a C/C++ programmer before getting in to android. I am not
sure how people maintain 2 versions of a program without using #ifdef
preprocessor macros. Right now I am changing the package name in
eclipse and changing the code manually, but this seems really
inefficient. Can anybody suggest a good way of having 2 or more
projects that share most of the code?

Re: [android-developers] Re: Ads in apps... How to successfully generate a larger revenue?

[Marc Lester Tan]

Yeah that is true. I have an app that's ~15k active installs and is gaining
$20/day while my other apps where active installs are  20k are just gaining
~ $1 a day. It really depends whether your users are actually using your
application very often.

 Because there are many other variables you probably aren't
 considering.. ones such as quality of the app/game, placement of the
 ads, content of the ad, fill rates, etc.  I seriously doubt you will
 find a definitive correlation between any two apps with regards to ad
 revenue.  Some of my free apps make more than my paid ones (exact same
 apps just with and without ads), and vice versa.

 I seriously doubt 60K users make anyone $150/day, especially using
 AdMob.  I've been using them for about 6 months now, so I'd have to
 see it to believe it.

You can try this one:

 Hi, thanks for your response.
 how do i give different z index?
 isn't it automatically when we call add() ?
 so i attach alParent.addView(mCameraView);  first and then
 alParent.addView(view);
 so isn't it means mCameraView at index 0, and view at index 1?
 but still i cannot see the opengl object, only camera preview

 when i change   alParent.addView(view);  first and then
 alParent.addView(mCameraView);
 i see the opengl object only...

  Hello,
 
  If you want one on top of the other you must use a FrameLayout and
  then give different z index to each when adding them as childs.

   Hi,
   i tried to have a GLSurfaceView on top of camera surface, so that i
   can draw gl objects with camera preview as background.
   I tried but didn't works. the view i has is something like this:
 
  
 
   AbsoluteLayout alParent = new AbsoluteLayout(this);
   alParent.setLayoutParams(new LayoutParams(LayoutParams.FILL_PARENT,
   LayoutParams.FILL_PARENT));
 
   //CameraView extends SurfaceView implements SurfaceHolder.Callback
   mCameraView = new CameraView(this);
   mCameraView.setLayoutParams(new AbsoluteLayout.LayoutParams(
  
 AbsoluteLayout.LayoutParams.FILL_PARENT,
  
 AbsoluteLayout.LayoutParams.FILL_PARENT, 0, 0));
   alParent.addView(mCameraView);
 
   //GLView extends GLSurfaceView
   view = new GLView(this);
   view.setLayoutParams(new AbsoluteLayout.LayoutParams(
  
 AbsoluteLayout.LayoutParams.FILL_PARENT,
  
 AbsoluteLayout.LayoutParams.FILL_PARENT, 0, 0));
   alParent.addView(view);
  
 
 
   it resulting the camera preview only, the opengl is not drawn. ( i
   made sure without camera, the opengl draws cube).
   Anyone have experienced this kind of situation?
   Thanks :)

[android-developers] Re: Application losing SharedPreferences and Sqlite database on Droid

[Marc]

I was recently was doing some file io stuff and discovered that when
debugging the application gets killed in a more drastic way than is
not possible on the phone. What I found is that if a debug session is
started during a file io write the data file gets corrupted. On the
phone you have to pull out the battery which just does not happen that
often.

[android-developers] Re: MediaPlayer failures on Android 2.1?

[Marc Reichelt]

Hi Mark,

thanks for your answer! It really is helpful.
I tried to reproduce the problem by creating an MP3 file on my own,
but the problem did not occur again. So I used my original testfile
and filed a bug:
http://code.google.com/p/android/issues/detail?id=7186

 Well, I can tell you that I can replicate your problem with your test
 MP3 file, even hosted from my Web server. I can replicate the problem on
 the Motorola DROID (Android 2.0.1) as well. And network speed doesn't
 seem to have an impact -- mine fails with a fairly snappy connection.

 OTOH, these Librivox poetry MP3 files work fine, and they are all
 shorter than your test file:

 http://www.archive.org/download/song_librivox/song_donne_mac_64kb.mp3http://www.archive.org/download/sonnet_23_librivox/sonnet_23_shakespe...http://www.archive.org/download/cow_stevenson3/cow_stevenson_ol_64kb.mp3

 So, file length is not the determining factor. In fact, I have not
 gotten a failure on anything other than your test file.

 So, while there certainly is a bug -- MediaPlayer shouldn't just quietly
 fail -- I do not think it is as widespread as you fear.

 If you can find a couple of legally-distributable files that exhibit the
 problem, package them and a sample project up and file an issue 
 onhttp://b.android.com.

Re: [android-developers] 3D Physics Engine For Android Demo

[Marc Lester Tan]

Works well on my Nexus One. Cool!

   I've completed my first Android application.   It as 3D demo with a
 physics engine.   It uses the phone's accelerometer so that you can
 shake the world by moving the phone around.   There are  options to
 adjust things like gravity, friction, and elasticity.

  The physics engine is a 100% Java port of the open source JigLib
 physics engine.

  However, I only have a Motorola Droid, and I don't know if it will
 work on any other phone.   The project is set to use Android 1.6.

  Before I put it in the market, I was hoping to get some feedback
 from the developer community here.

  If anybody is interested in 3D stuff or physics simulation, you can
 give the app a try.   The link is on the follow page.   There is a
 screen shot there so you can get an idea of what the app is.

[android-developers] MediaPlayer failures on Android 2.1?

[Marc Reichelt]

Hi there!

I developed an audioplayer for Android for our new project which plays
local and online files. It works great on the G1, but somehow often
fails on the Nexus One when streaming MP3s from the Internet -
especially smaller files.

The problem is that I am using the prepareAsync() method and an
OnPreparedListener but somehow onPrepared() is not called sometimes -
especially when the network is slow. So I am creating a MediaPlayer
object, set the OnPreparedListener, call setDataSource() with an URL
in it and call prepareAsync() - but onPrepared() is not called,
leaving the MediaPlayer in the completely useless transient state
Preparing. And there seems to be no way to catch this failure.

This is the code I used to track down this error:

--- file: TestMediaPlayer.java ---
package de.marcreichelt.android.testmediaplayer;

import android.app.Activity;
import android.media.MediaPlayer;
import android.media.MediaPlayer.OnPreparedListener;
import android.os.Bundle;
import android.util.Log;

public class TestMediaPlayer extends Activity implements
OnPreparedListener {

private static final String TAG =
TestMediaPlayer.class.getSimpleName();

@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);

MediaPlayer mp = new MediaPlayer();
mp.setOnPreparedListener(this);

try {

// Music from World of Goo Soundtrack
// see http://kylegabler.com/WorldOfGooSoundtrack/ :-)

Log.d(TAG, mp.setDataSource());

mp.setDataSource(http://marcreichelt.de/misc/android/test.mp3;);
Log.d(TAG, mp.prepareAsync());
mp.prepareAsync();

} catch (Exception e) {
Log.e(TAG, , e);
}

}

@Override
public void onPrepared(MediaPlayer mp) {
Log.d(TAG, mp.start());
mp.start();
}

}
--- end of file ---

To test this code I created a new AVD with Google 7 API / Android 2.1
and set the Emulator speed to GPRS (important!). I use the Android
1.6 SDK for compiling my project and minSdkVersion is 4.

This is what I get in Logcat:
03-15 20:31:21.354: INFO/ActivityManager(63): Starting activity:
Intent { act=android.intent.action.MAIN
cat=[android.intent.category.LAUNCHER] flg=0x1020

(total 440 ms)
03-15 20:31:21.946: INFO/PlayerDriver(31): buffering (1)

The method onPrepared() is not called, so I am not able to call
start() on the MediaPlayer object.


Can anyone confirm this problem? Is this a bug in the Android 2.1 SDK
(or maybe 2.0.1, too)? And what can I do to solve this?


Thanks in advance  regards
