 Anything basic I've missed?

if you want your app when phone starts you shall create broadcast receiver:

receiver android:name=.BootReceiver
 intent-filter
  action android:name=android.intent.action.BOOT_COMPLETED /
 /intent-filter
/receiver

and add

uses-permission android:name=android.permission.RECEIVE_BOOT_COMPLETED /

Re: [android-developers] Re: Services and battery life

2011-01-12 Thread Dianne Hackborn

There is absolutely no benefit to keeping the service running during that
time.  If you want to avoid work when it starts every 5 minutes, keep your
previous work in static globals to re-use the next time the service is
created.  All you do by keeping the service running is that if the system is
running low on RAM it can't do as good a job at deciding which processes to
throw away, because you are not giving it good information about how
expendable your process is.

This also makes it more likely that in such a situation it will decide to
kill your process while it is actually actively doing stuff, because it will
think that the service has been sitting there running for a long time.
 Android considers long-running services to be better candidates to kill
than those that were more recently started.

 Well, if really necessary, one could show a notification and use
 startForeground.

 I for one would go for a compromise: Use AlarmManager for the timing,
 unless you really, really need to be as exact as possible (Android is
 a multitasking system, and services usually don't have highest
 priority, so there'll always be some lack). But don't stop the service
 until after the 30 minutes are over. This way, you only have to do all
 the initialization work if the system killed your service, while
 AlarmManager saves you from aborted updates and having to use wake
 locks while idle.
 I think for as short as 30 minutes it's OK to keep the service running
 mostly idle if this saves the system from having to load and
 initialize every 5 minutes. Esp. if this might be connected with
 restarting GPS and searching for sattellites again and again...

[android-developers] Call Recording issue

2011-01-12 Thread chetan

Hi All,
I am writing an application to record the call. I have created
an Activity for UI and a Service to start and stop record.

In Service to start record, the code is

MediaRecorder recorder=new MediaRecorder();
File  root=Environment.getExternalStorageDirectory();
File recordfile=new File(root,call_file.3gp);

Log.d(TAG,FilePath::+recordfile.getAbsolutePath().toString());
recorder.setAudioSource(MediaRecorder.AudioSource.VOICE_CALL);
recorder.setOutputFormat(MediaRecorder.OutputFormat.THREE_GPP);
recorder.setAudioEncoder(MediaRecorder.AudioEncoder.AMR_NB);
//recorder.setOutputFile(/data/data/com.example.CallRecorder/
call_file);
//this.getFilesDir();
Log.d(TAG,set path to sdcard);
recorder.setOutputFile(/sdcard/call_file.3gp);
try {
recorder.prepare();
} catch (IllegalStateException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
   recorder.start();
///

After executing a call and starting record, my app is hang and then
ANR alert is coming to close it.
Even i am destroying record service and release recorder , the app is
still hang. It seems that my app loose the control.

The logs coming in loop are:

[android-developers] Re: Theme.Dialog bug in 2.1?

2011-01-12 Thread Schoel

Is the topmost activity intended to occupy the screen without being
visible? I don't mind the entire activity stack popping up when this
happens, but the topmost dialog is not even visible but it's still
there. This is not the case when using 2.2, like I described above, so
something has been changed.

Hello,

I have found some weird behaviour which might be a bug. I found it
while developing a quite large application but I've been able to
reproduce the behaviour in a minimal approach so that I can provide
source code.

I have a service that is constantly running and at certain times it
pops up an activity with Theme.Dialog as theme for the user.
Everything works fine if the main activity of the program has been
destroyed (via back button) or if the main activity is currently
running.

However, if the main activity of the app has been created and then
minimized (e.g. via Home button), the main activity shows up. It is
not possible to click the buttons of the main activity because it
seems to be hidden behind an invisible dialog activity. It is possible
to click the buttons of the dialog if you know where they are and if
you click the back button, you can see the dialog flashing by as it
disappears and it is then possible to click the main activity buttons.

I've tested this on HTC Desire 2.2, HTC Wildfire 2.1, HTC Legend 2.1,
Sony x10 mini pro 2.1 and on emulators 2.1 and 2.2. The behaviour
described happens on all 2.1 devices and emulator but not on emulator
2.2 nor on the Desire with 2.2.

Source code is provided below. There are 2 buttons in the main
activity, the first, called Finish asks the service to popup the
dialog in 3 seconds and then finishes the main activity. This button
is for illustrative purposes only, it works fine. The second button,
called Post later just asks the service to popup the dialog in 3
seconds. If the second button is clicked and before the 3 seconds have
passed, the home button is clicked, the bug appears.

Source code:
Main.java:
--
package com.myapp.DialogBugTest;

[android-developers] image background - how to repeat an image rather than strech it

2011-01-12 Thread liordav

Hi,
I have an image I want to use as a background to some layout.
the problem is the image contains a texture of slant lines, so if i
use a 1 pixel width image or a 9 patch the image is stretched and the
texture is Twitching, so i can see the slant lines as latitude lines.
I saw that he android emulator uses a similar texture in the progress
bar indeterminate animation, is there a special/simple definition to
order the background image to repeat itself rather than stretch? is
there a way to do it with 9 patch, cause eventualy i also need the
corners to be round.
thanks for the help.

[android-developers] Soft keyboard alters layout

2011-01-12 Thread Neilz

Hi all.

I have a layout which comprises a central section (for listview etc)
and a navigation bar which is fixed at the bottom.

When the soft keyboard pops up, the view is compacted to make way for
it, and my nav bar gets pushed halfway up the screen which just looks
daft.

Is there a way I can stop this? Surely the keyboard can act as a frame
and overlay the existing views?

Thanks.

[android-developers] Can I launch executable file under Jni level?

Re: [android-developers] Re: JNI working

Native code is... well native.

An .so packaged within an application contains machine code and runs
directly on the processor (unlike .dex code).

[android-developers] Calculating screen coordiantes in augmented reality???

2011-01-12 Thread prachi

Hi

Iam developing an augmented reality browser on my ownn...But
not able to get the screen cooridinates

I will discuss my whole problem here.as im not sure at which point
i stuck up...

I hav a set of latitude longitude values for different points.Taking
them Iam calculating x,y,z coordinates for each point.Using left
handed rule ie.x towards east y towards north and z upwards
values which i get are:-

x=(a+altitude)*(Math.cos(latitude)*Math.sin(longitude));//x
y=(a+altitude)*Math.sin(latitude);//y
z=(a+altitude)*(Math.cos(latitude)*Math.cos(longitude));//z

where a=app 80m i have taken radius of earth.The origin is defined to
be at centre of earth(ECEF)

SensorManager.getRotationMatrix(RTmp, I, grav, mag);
SensorManager.remapCoordinateSystem(RTmp, SensorManager.AXIS_X,
SensorManager.AXIS_Z, R);
SensorManager.getOrientation(R, values);
azimuth = (float)((values[0])*(180/Math.PI)); //in degree
pitch = (float)((values[1])*(180/Math.PI)); //in degree
roll = (float)((values[2])*(180/Math.PI)); //in degree

Then using perspective projection Iam calculating screen coordinates.
Iam refering below link for perspective projection:--

http://en.wikipedia.org/wiki/3D_projection#Perspective_projection

In the above link Iam replacing thetax with pitch,thetay with
roll,thetaz with azimuth.

Watever screen coordinates i got from above calculations Iam plotting
a circle using canvas.But Iam unable to see anything.

Pleae help as Iam stuck up with this for the past 3 dayzzz :( :(

[android-developers] about content provider physical store location

2011-01-12 Thread stanly

hi all,

I have a question about content provider,
for example,
I used the *Telephony.Carriers.CURRENT* this URI to store all APN nodes,
maybe it will has 100 nodes(records) in it.
but when I insert the 100 rows data via *ContentResolver.insert*
pragramatically,
instead of inserting records in every product by code, I wish my every
product can have these 100 rows data atomatically,
so I think there must exist a *real physical store location* to store the
*Telephony.Carriers.CURRENT* URI all records, like xxx.db.
so that I can just copy the xxx.db to every products, and used these
records.

is there have a physical location to store records in URI?

please give me some suggestion.

thanks a lot!!

 If you want to avoid work when it starts every 5 minutes, keep your

To clarify, you will need to ensure that you can reload those static
globals as needed. While the process probably sticks around between
alarms, it might not, in which case those globals will be null and you
will have to regenerate that data. Consider these static globals to be
an optimization, not a load-bearing beam of your app.

2011-01-12 Thread DanH

 No.  You can only modify it so far as it doesn't break existing
 applications.  That can be very limiting.

But you can replace the entire thing with NumberChooser when you
need to make a clean break.

 Many classes that are public make use of private classes for implementation.
  That isn't a reason to make those other classes public.

  And you should be aware that everything that already exists in
  the core system will be seen as standard template, and so there are
  already several apps which copied the NumberPicker or wrote own,
  similar looking ones.

 Um.  Yeah.  It's open source.  If there is something in the open source code
 you like but isn't in the SDK, copy it out, make sure it builds against the
 SDK, and use it.  That's one of the benefits for developers of things being
 open source.

  Isn't the big advantage of Widgets that you can completely replace
  code and appearance as long as you keep the interface compatible?

 No.  You can only modify it so far as it doesn't break existing
 applications.  That can be very limiting.

  I'm
  afraid you'll now see the bad old NumberPicker way longer in apps
  which copied it than it would've been the case if you offered a public
  interface and one day replaced it with another implementation - just
  like it might happen with the date and time pickers.

 We can live with that.

  Admit it - you just wanted to lead developers to the wonderful world
  of the Android source code and git by forcing them to get the
  NumberPicker from there. ;)

 People are absolutely welcome to pull stuff out of the open source code that
 they find useful.  One of the gratifying things about working on Android is
 that all of our work is available to everyone to freely do what they want
 with it.

  No, seriously. I appeciate your work. I might think different in some
  topics, but you did a wonderful job with Android.

 Thanks, I appreciate it. :)

[android-developers] How to optimize an image app for various devices and screen resolutions

2011-01-12 Thread Johan

Hi there,

I'm working on an app which displays various images. I want to
optimize this for the various screen resolutions. The MultiResolution
(1) tutorial uses many resource qualifiers in the res folder to
display the appropriate images for the various device resolutions, but
how do you package this? I don't want to ship the images for all
devices (or do I?). I want to keep the download size as small as
possibel, so I only want to package the ones for that particular
screen resolution. Or, should I forget packaging images and put the
images on-line somewhere?

Any opinions on this subject would be appreciated

 Hi

 Iam developing an augmented reality browser on my ownn...But
 not able to get the screen cooridinates

 I will discuss my whole problem here.as im not sure at which point
 i stuck up...

 I hav a set of latitude longitude values for different points.Taking
 them Iam calculating x,y,z coordinates for each point.Using left
 handed rule ie.x towards east y towards north and z upwards
 values which i get are:-

 x=(a+altitude)*(Math.cos(latitude)*Math.sin(longitude));//x
 y=(a+altitude)*Math.sin(latitude);//y
 z=(a+altitude)*(Math.cos(latitude)*Math.cos(longitude));//z

 where a=app 80m i have taken radius of earth.The origin is defined to
 be at centre of earth(ECEF)

 SensorManager.getRotationMatrix(RTmp, I, grav, mag);
                 SensorManager.remapCoordinateSystem(RTmp, 
 SensorManager.AXIS_X,
 SensorManager.AXIS_Z, R);
                 SensorManager.getOrientation(R, values);
                 azimuth = (float)((values[0])*(180/Math.PI)); //in degree
                 pitch = (float)((values[1])*(180/Math.PI)); //in degree
                 roll = (float)((values[2])*(180/Math.PI)); //in degree

 Then using perspective projection Iam calculating screen coordinates.
 Iam refering below link for perspective projection:--

 http://en.wikipedia.org/wiki/3D_projection#Perspective_projection

 In the above link Iam replacing thetax with pitch,thetay with
 roll,thetaz with azimuth.

 Watever screen coordinates i got from above calculations Iam plotting
 a circle using canvas.But Iam unable to see anything.

 Pleae help as Iam stuck up with this for the past 3 dayzzz :( :(

Hard to give a direct answer from that far. Did you fire up the
debugger and check the coordinate values you get? If they hit the
screen and you do not see anything, the problem is some place else,
drawing the overlay. (This doesn't mean you've necessarily got the
math right, but at least it's a start).

[android-developers] Re: Anyone know how to calculate speed WITHOUT GPS?

2011-01-12 Thread Brill Pappin

Well you pretty much need distance traveled over time to find speed,
so anything you can do to determine distance travelled should allow
you to calculate the speed.

For instance you could use cell tower location, but I wouldn't class
it as even remotely accurate.
If you want to give an actual real value, your going to need the
accuracy of the GPS unit.

Yah, that is used a lot in simple robotics.
You can't actually get anything accurate though. the longer the
distance traveled the more inaccurate it becomes.

 To clarify, you will need to ensure that you can reload those static

 alarms, it might not, in which case those globals will be null and you
 will have to regenerate that data. Consider these static globals to be
 an optimization, not a load-bearing beam of your app.

You don't need to do that on the phone. Simply set up a linux box as a

Trying to do this on a phone is a waste of time, in fact I'd say the
only reason to do this was for hacking other peoples phones.

[android-developers] Strange NoClassDefFoundError from Bitmap.compress()

2011-01-12 Thread String

I've got a real head-scratcher here, folks. At least it is for me.

Quite recently (last couple of days?), I've begun to see the following error 
in my Console:

FATAL EXCEPTION: main
java.lang.NoClassDefFoundError: android.graphic3.Bitmap$CompressFormat

and the line that's throwing it looks like this:

bitmap.compress(CompressFormat.PNG, 100, fos);

where bitmap is, not surprisingly, and ordinary Bitmap, and fos was 
declared like this:

FileOutputStream fos = new FileOutputStream(filename);


Now, this Bitmap.compress() call has been working fine, without 
modification, for a year and a half. Given it's writing to the filesystem, I 
could imagine it might be an IO error of some sort - except that I'm 
trapping IOException already, and of course, the error thrown 
is NoClassDefFoundError. So I'm stumped. It looks like the system is 
suddenly unable to find either CompressFormat or CompressFormat.PNG, but 
that doesn't make any sense at all.

Any ideas?

[android-developers] pause AudioTrack correctly

2011-01-12 Thread Markus Drösser

Hello,

I hope that somebody can explain how to pause AudioTrack correctly. I
am recording and playing back a pcm file with the
OnPlaybackPositionUpdateListener in a remote service. This works fine.
Now when I call pause() on the audioTrack object, the playback pauses
and if I want to resume I call start() again. This works in general,
but some frames are skipped and the playback does not resume from the
point it paused but from a few frames later. Why is that? Please show
me how to pause a AudioTrack correctly without losing frames. Here is
my code for the PlaybackListener


audioTrack.setPlaybackPositionUpdateListener(new
OnPlaybackPositionUpdateListener() {

@Override
public void onPeriodicNotification(AudioTrack 
track) {

try {
int error=0;
if(ramfile!=null)
{
error = 
ramfile.read(buffer);
}

if(error==-1)
{

audioTrack.stop();

audioTrack.flush();

if(ramfile!=null)
ramfile = null;
audioTrack=null;
playing=false;
}

if(audioTrack!=null 
audioTrack.getPlayState()==AudioTrack.PLAYSTATE_PLAYING)

audioTrack.write(buffer, 0, buffer.length);


} catch (IOException e) {
Log.d(EX,We run into an 
Exception);
e.printStackTrace();
}
}

@Override
public void onMarkerReached(AudioTrack track) {

}
});


Greetings,

Markus

[android-developers] HTML5 audio and video support

2011-01-12 Thread ls02

I am trying to figure out of android (at least Froyo) has any audio
and video HTML5 tag support in any form or shape. I read from many
sources and http://www.html5test.com confirms that although Android
Web browser does support both tags it does not support any audio or
video codecs which basically makes these tags not supported.

At the same time I read in some references that some people may have
found a workaround how to play audio inside a Web browser for instance
by specifying mp3 file source for video tag.

http://code.google.com/p/android/issues/detail?id=10546

I tried this on my Droid and no clip is played or displayed, only a
placeholder is shown.

Can someone point me to at least one working example (link to a page)
that plays any sort of audio inside a Web browser on Android. If it is
absolutely not possible to play audio via HTML5, is there any way to
launch Android music player to play the mp3 link in some sort of
hidden or minimized form so it does not take over entire screen and
navigate user away from a Web page?

My Need  : I want to have a database as part of the system image ( That is 
when i flash the image/APK) . The database should be present already rather 
than me populating when i launch the service.here my use case is that 
database can be accessed by any app  in read only mode but the database 
value is written by my service only.so i just want the database being

This is the wrong list to be discussing this. But just as learning
Java by programming in Android is hard, learning C by programming in
Android is definitely doing it the hard way! Doing this sort of
experimentation under Ubuntu, say, would let you use a real debugger.

You're passing a null pointer to execv. The second argument must be an
array of char* pointers, the last of which should be a null pointer.
An array of one null pointer is NOT the same as a null pointer! In
fact, it shouldn't have even compiled, since char* is not char**!

You're only initializing the first 4 bytes of your buff array.
sizeof(100) = 4 most likely. You want  100*sizeof(char).

You didn't really do the right test under adb. If you're going to

[android-developers] Re: Strange NoClassDefFoundError from Bitmap.compress()

2011-01-12 Thread Bob Kerns

ClassNotFoundError can mean it got an error while loading the class.
Perhaps it ran out of memory, just as it was loading this class?

You could try doing this first thing in your app on some small bitmap,
to preload the class, and see if that changes things. I wouldn't
consider that a workaround -- just a way to investigate the cause.

On Jan 12, 6:51 am, String sterling.ud...@googlemail.com wrote:
 I've got a real head-scratcher here, folks. At least it is for me.

 Quite recently (last couple of days?), I've begun to see the following error
 in my Console:

 FATAL EXCEPTION: main
 java.lang.NoClassDefFoundError: android.graphic3.Bitmap$CompressFormat

 and the line that's throwing it looks like this:

 bitmap.compress(CompressFormat.PNG, 100, fos);

 where bitmap is, not surprisingly, and ordinary Bitmap, and fos was
 declared like this:

 FileOutputStream fos = new FileOutputStream(filename);

 Now, this Bitmap.compress() call has been working fine, without
 modification, for a year and a half. Given it's writing to the filesystem, I
 could imagine it might be an IO error of some sort - except that I'm
 trapping IOException already, and of course, the error thrown
 is NoClassDefFoundError. So I'm stumped. It looks like the system is
 suddenly unable to find either CompressFormat or CompressFormat.PNG, but
 that doesn't make any sense at all.

 Any ideas?

Re: [android-developers] Sqlite Database in the APK

If you need to provide data to other applications, consider implementing 
a ContentProvider:


http://developer.android.com/reference/android/content/ContentProvider.html

This has the following benefits in your described use scenario:

- You can protect your data by declaring read and/or write permissions 
for the content provider in your manifest;


- CP lifecycle is managed by Android, it will be loaded and initialized 
as soon as it's needed (based on the authority URI);


- You keep implementation details private to your CP code (the database 
schema, the mapping between URIs and tables, etc.);


- Your CP will be instantiated only once, so you won't need to solve any 
problems like is the database already open, and in which process;


- The framework provides URI-based data update notifications that can be 
observed by ListViews and their CursorAdapters, so you can get live 
views into your data at little or no extra effort.


If you're creating custom firmware with your application pre-installed, 
you can still use a CP and get the benefits described above, but in 
addition, you can require that only applications signed with the 
firmware key are able to get write access to your data (for an example, 
look at the standard email application in Android source).

Re: [android-developers] EditText with Cross


- Add a button to your layout;

- Add an OnClickListener to the button;

- In the listener's onClick, call editText.getText() to get the Editable 
object and call clear() on that.

[android-developers] Problem changing Activity title in onActivityResult()

I posted this over at StackOverflow, but not much of a response...
maybe someone else can run this on their testbed and verify?  A
strange problem...

==

Hi all.  I have a simple app based on the Notepad demo application,
and when a user is viewing/editing a note they can launch a dialog
activity (TitleEditor) that allows them to change the title of a note.
Currently in the app, when viewing/editing a note, the notes' current
title is shown as the activity title.

So, I launch the TitleEditor dialog activity with
startActivityForResult(), and in onActivityResult() I am successfully
getting the new title back, no problem.

The issue relates to then updating the notes view/edit (the active
activity) title... using setTitle() in onActivityResult() with the
data passed back does seem to set the title internally (a subsequent
call to getTitle() shows the new title has been set), but the actual
UI title is not updated until the activity is closed and then re-
launched.

I've used setTitle() in onResume(), onPrepareOptionsMenu(), etc and it
worked like a charm, but not working here... any ideas or suggestions?

Thanks,

Paul

[android-developers] Re: Accessing Facebook photos from the Contacts provider

2011-01-12 Thread Biosopher

After scouring the web and confirming it myself, Facebook's photos are
stored in a manner that prevents access by other apps.  This inability
to access Facebook sync'd photos is a side effect of how Facebook
syncs contacts.

Facebook creates an account on the device using Android's
AccountManager (http://developer.android.com/reference/android/
accounts/AccountManager.html) which creates a secure space in which an
app can store sync'd contact information.  Using AccountManager to
create accounts for storing contact information is the Android
recommended way to sync contact information.

Short of it then?  Facebook's uses the standard Account/Contact
syncing functions built into Androidand these functions prevent us
from getting those photos.  Makes sense from a security and
permissions perspective.

From what I understand, ATT uses GSM and Verizon uses CDMA, which are
different technologies. So it is some what carrier specific only because
each US carrier offers a different technology.

 Very cool. That makes sense.

 Are you sure it's not carrier specific? The reason I ask is because I 
 have 2 phones both with 3g service one on Verizon and one on ATT. The 
 ATT android phone can surf the net and what not while on the phone, 
 my Verizon phone and my boss's phones cannot.

 That part isn't a huge deal though.

 Again thank you for your time!

 It's not a carrier fault. Some data xfer standards (i.e. EDGE) cannot 
 operate while doing phone call. If you use GPS receiver then it's 
 completely different hardware and not interfere with phone radio. 
 However if you want to use cell traingulation instead of GPS receiver 
 then it needs data connection to map cells to certain location. And it 
 of course may be not available when on the call if the situation I 
 formerly described occur

Yes, you can create your database anywhere using SQLite tools, and 
package it with your application (assets / raw).


The first the app is run, open the packaged database as a stream, and 
copy it into a file where your application has read/write access.


This can be the memory card or the path returned by 
Context.getDatabasePath(). If it's the latter, you'll then be able to 
use SQLiteOpenHelper to open the database.

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] Re: Problem changing Activity title in onActivityResult()

Agreed, which is why it's so frustrating.

As a test, in onCreateOptionsMenu()

@Override
public boolean onCreateOptionsMenu(Menu menu) {
setTitle(changed);
.
.
.
return super.onCreateOptionsMenu(menu);
}

Works fine.  In onActivityResult() (this is the code, verbatim)

@Override
protected void onActivityResult(int requestCode, int resultCode,
Intent data) {
super.onActivityResult(requestCode, resultCode, data);

// check the activity results
switch (requestCode) {
case RESULT_RENAME:
if (resultCode == -1) {
// activity ended successfully
Log.d(LOG_TAG, onActivityResult():

data.getStringExtra(StylePad.Notes.TITLE));

setTitle(data.getStringExtra(StylePad.Notes.TITLE));
Log.d(LOG_TAG, onActivityResult():
New title  + getTitle());
}
break;
}
}

And the logging tells me that the title's been changed, but yet the UI
is NOT updated...  Have tried this on both a Galaxy Tab (2.2) and the
2.2 emulator.

  Hi all.  I have a simple app based on the Notepad demo application,

  I've used setTitle() in onResume(), onPrepareOptionsMenu(), etc and it
  worked like a charm, but not working here... any ideas or suggestions?

[android-developers] Re: How to get screen density in pixels-per-inch or equivalent

2011-01-12 Thread Phil Endecott

  Note that some devices don't correctly report actual resolution (xdpi /
  ydpi).

 Does some devices include anything that I care about?  How wrong is
 the value?

Answering my own question: yes, it is wrong on my Motorola Defy, which
returns 96.  Googling tells me it is wrong on quite a lot of devices
from Motorola.  Aaarrgg.

So: is the value 96 that I see a sentinel that I can use to detect
this bug?  I.e. do all/most devices with this bug return 96?  If so,
I'll trap 96 and substitute something else, e.g.
DisplayMetrics.displayDpi(), which I trust is more reliable.  If 96 is
not the only wrong answer, can anyone suggest some other way to detect
a bogus value here?


Thanks,  Phil.

[android-developers] onItemSelectedListener causes gallery to jump, stick and pop...

2011-01-12 Thread Richard Schilling

I have a gallery on my screen.  Works great and scrolls smoothly ...
until I set the OnItemSelectedListener.  When I do, Gallery gets
really jerkey.  It seems to stick.  I think I know why, but I was
wondering if others have found a better solution they would be willing
to share.  Here's my onItemSelectedListener:


myGallery.setOnItemSelectedListener(new 
OnItemSelectedListener(){
@Override
public void onItemSelected(AdapterView? parent, View 
view,
int position, long id) {
// do nothing on purpose to see what the effect 
is
if (view == null)
return;


Message msg = Message.obtain();
msg.obj = view.getTag();
_handler.sendMessage(msg);

}
   }});

And here is the handler:


private Handler _handler = new Handler(){
public void handleMessage(Message msg){

if (msg.obj != null  msg.obj instanceof String){

textView1.setText(msg.toString());
textView2.setText(msg.toString().length();
}
}
};


When the UI thread updates the controls with the data, it seems to
interrupt the scrolling of the gallery itself and causes the gallery
to not scroll smoothly.  Commenting out the handler code eliminates
the problem.

So, I know the problem has to do with the fact that the UI just can't
update the text controls and keep the gallery scrolling smoothly at
the same time.

Does anyone have a work around for this problem?

Thanks in advance!

[android-developers] Sharing preferences between apps?

2011-01-12 Thread John Lussmyer

I have an app that needs to be able to pass a set of settings to my Live
Wallpaper.
The Live Wallpaper already saves these in a Shared Preferences file.
I did a bunch of searches, and found a possible way for the app to access
the wallpapers Shared prefs was:
(I've also set both apps to have the same uid in their manifest files.)

Context context =
this.createPackageContext(com.casadelgato.lifewallpaper, 0);
SharedPreferences wPrefs =
context.getSharedPreferences(Constants.LW_SHARED_PREFS, 0);
Editor editor = wPrefs.edit();
editor.putBoolean(Constants.PREF_RANDCOLORS,
engine.isRandColors());
etc...

When I try, I get:

01-12 10:37:20.728: WARN/ApplicationContext(293): Attempt to read
preferences file
/data/data/com.casadelgato.lifewallpaper/shared_prefs/lifewallpapersettings.xml

Am I missing something?  Or is this just the wrong way to do it.

Re: [android-developers] Re: Problem changing Activity title in onActivityResult()


Maybe you can glean something from the source:

http://android.git.kernel.org/?p=platform/frameworks/base.git;a=blob;f=core/java/android/app/Activity.java;h=f25c4c385e4f510bec426fbef801243e4c149f69;hb=cb8427538dfdc5eae941e377b11bfd11a95fc5a5

Looks like the title will only be changed if mTitleReady is true, which 
is set in onPostCreate.


You could add logging to onCreate, onActivityResult and your own 
overriden onPostCreate, just to see in what order they get called. If 
the order is not what you expect, try saving the title in 
onActivityResult and change it in your overriden onPostCreate.

[android-developers] Re: How to get screen density in pixels-per-inch or equivalent

2011-01-12 Thread Richard Schilling

Did you try fetching the scale that will allow you to convert from DPI
to actual screen pixels?  I found this very reliable:

 final scale =
getContext().getResources().getDisplayMetrics().density;

Then multiply scale by one inch of pixels in DPI resolution (depending
on the screen you're on) - 120, 160, 240, 320.

This API call ...

 int densityDpi =
getContext().getResources().getDisplayMetrics().densityDpi;

will tell you the density of the screen you're on.  See
http://developer.android.com/reference/android/util/DisplayMetrics.html#densityDpi
for more information.

So, this will tell you how many screen pixels equate to an inch.  Then
you can use that to lay out your ruler markings:
 int pxPerInch = 340; // default value - note it's a new density
in API version 9.

 switch(densityDpi){
  case DisplayMetrics.DENSITY_LOW:
  pxPerInch = 120 * scale;
  break;
  case DisplayMetrics.DENSITY_MEDIUM:
  pxPerInch = 160 * scale;
  break;
  case DisplayMetrics.DENSITY_HIGH:
  pxPerInch = 240 * scale;
  break;
 }

I haven't tested that but it, or some derivation of this should tell
you how many screen pixels comprise one inch on the screen.

Hi all.  I have a simple app based on the Notepad demo application,
and when a user is viewing/editing a note they can launch a dialog
activity (TitleEditor) that allows them to change the title of a
 note.
Currently in the app, when viewing/editing a note, the notes' current
title is shown as the activity title.
 
So, I launch the TitleEditor dialog activity with
startActivityForResult(), and in onActivityResult() I am successfully
getting the new title back, no problem.
 
The issue relates to then updating the notes view/edit (the active
activity) title... using setTitle() in onActivityResult() with the
data passed back does seem to set the title internally (a subsequent
call to getTitle() shows the new title has been set), but the actual
UI title is not updated until the activity is closed and then re-
launched.
 
I've used setTitle() in onResume(), onPrepareOptionsMenu(), etc and
 it
worked like a charm, but not working here... any ideas or
 suggestions?
 
Thanks,
 
Paul

[android-developers] Listview highlight problem

2011-01-12 Thread Nikola

Hi,

when I set listener like

row.setOnLongClickListener(new OnLongClickListener() {

@Override
public boolean onLongClick(View v) {



my listview doesn't highlights items on touch.


Does anyone knows what could be source of this problem and how to resolve
it?

tnx.

[android-developers] Re: Problem changing Activity title in onActivityResult()

Yes!  I was changing the title of a note in the db in the called
activity, but failing to update the cursor in onActivityResult... so
in onResume, it was pulling the old title.  .requery()ing the cursor
in onActivityResult got it, thanks all!

  Ok, so it looks like the following is happening...  User starts the

  Z to onActivityResult, I then attempt to change the UI title again

[android-developers] Re: How to get screen density in pixels-per-inch or equivalent

2011-01-12 Thread Phil Endecott

Hi Richard,

On Jan 12, 6:54 pm, Richard Schilling richard.rootwirel...@gmail.com
wrote:
 Did you try fetching the scale that will allow you to convert from DPI
 to actual screen pixels?  I found this very reliable:

  final scale =
 getContext().getResources().getDisplayMetrics().density;

The description of that says:

on a 160dpi screen this density value will be 1; on a 120 dpi
screen
it would be .75; etc.

 Then multiply scale by one inch of pixels in DPI resolution (depending
 on the screen you're on) - 120, 160, 240, 320.

 This API call ...

  int densityDpi =
 getContext().getResources().getDisplayMetrics().densityDpi;

 will tell you the density of the screen you're on.

Approximately.

 So, this will tell you how many screen pixels equate to an inch.

I'm not at all sure that it does.

  Then
 you can use that to lay out your ruler markings:
  int pxPerInch = 340; // default value - note it's a new density
 in API version 9.

  switch(densityDpi){
   case DisplayMetrics.DENSITY_LOW:
   pxPerInch = 120 * scale;
   break;
   case DisplayMetrics.DENSITY_MEDIUM:
   pxPerInch = 160 * scale;
   break;
   case DisplayMetrics.DENSITY_HIGH:
   pxPerInch = 240 * scale;
   break;
  }

Note that the values of those constants DENSITY_* are their numeric
values, so there is no need for the case statement; you can just
write:

pxPerInch = densityDpi * scale;

However, I really don't think that does what you believe it does.  I
think that densityDpi reliably gives the approximate dpi, and density
just gives densityDpi/160.  Multiplying them together doesn't do
anything useful.  But I could be wrong!

Thanks,  Phil.

[android-developers] Particularity running modified standard app

2011-01-12 Thread Bernard T. Higonnet


Hello,

I have downloaded and slightly modified the Android 2.2 version of
Camera and have begun to make some changes to it.

Let's say I have renamed the app to X in Eclipse

If I run X from Eclipse (Helios), it behaves more or less the way I
expect. Running from Eclipse installs X on my device (Nexus One). But
when I run X from the app launcher, I get Camera!

I would be thankful to

1) know why
2) general info on modifying a standard app

TIA
Bernard Higonnet

[android-developers] Re: EditText with Cross

2011-01-12 Thread Richard Sámela

Yes that I know but I would like to do that the Button will be inside
of EdiText. The Button will be a little bit like a cover of EditText.
Is it possible to set the Button position to be above the EditText??
thanks for answering.

It might just be a regular button beside the EditText. And I guess that's
very simple to implement.

Hi,
I saw an app where was EditText and if you put some text into EditText
there was a Cross Button (or something like that) on the left side.
And if I click on this Button the text from EditText was deleted. Can
you help me or explain me how to to this? I would like to use EditText
with the same effect.

Re: [android-developers] HttpURLConnection gives UnknownHostException

Somehow I have this feeling it is related to my app only.  Other apps on the
phone, I don't see any such issue.  Even when browsing on my phone, I don't
see any error.

 By Wi-Fi, I meant, you phone's Wi-Fi could be turning on and off. There is
 no other reason I can think of. It happens for me as well, sometimes.

 I am sorry, that somehow doesn't convince me.  I am connected to the same
 wifi on my laptop and i never see any web page load error on my laptop.

 Yup, then it's a problem with your Wi-Fi.

 Hi All,

 I am developing an application on Android.  I have seen that at times
 when I try to connect using HttpURLConnection, for getting an Image or
 anydata, I get the following error:

 01-12 11:24:05.073: WARN/System.err(16780):
 java.net.UnknownHostException: Host is unresolved: www.XXX.com:80.

 Note: I get this error on my Motorolla Droid and not in emulator.

 Any ideas?


 Thanks,
 Ankur
