Delete the XML from drawable-ldpi/ and make sure you have the pngs in
both drawable/ and drawable-ldpi/ (at different sizes of course).

 Roman,

 Thanks for the quick response! Unfortunately, I'm still having issues.
 It wasn't clear to me whether you were instructing me to just delete
 the selector xml file in drawable-ldpi, or copy the one from drawable
 into drawable-ldpi without change. I've tried it both ways to no
 avail.

 I don't have a layout-small set of resources yet. I shouldn't need
 layout-small for this one issue should I?

 It is not the right way. Do not use @drawable-ldpi/, just keep the

  No love. I get:

  Isn't this the right way to specify ldpi specific button images? If
  default device xmls and pngs go in drawable, then ldpi xmls and pngs
  go in drawable-ldpi, right? Could these errors be the result of an
  inappropriate supports-screens element in my manifest file?

  Neither the api-demos in the samples (for any SDK version), or the
  newer samples including multires, have any multi res image button
  examples. In fact, I couldn't find any example where there was an xml

  Anyone see what I'm doing wrong and/or have a working example of how

[android-developers] Re: Resource not found errors for images referred to in a button image selector xml file

Instead of

try
android:drawable=@drawable/startstopin
Just like you do for your normal HVGA screen. On small screens it will
automatically look in the -ldpi directory and pick these images
ahead of those in the default dir

 Any insight into this problem would be greatly appreciated.

[android-developers] how to clear activity stack in task

2010-01-06 Thread Zhihong GUO

Hi all,

I have three activities. Activity A start activity B by the method
startActivityForResult, and Activity B start activity C by the method
startActivity. Then, after starting activity C, activity B kill himself by
finish(). Now the task stack stored two activities: A and C.

My question is: how can I finish activity A when I finish activity C. or how
can I clear the whole stack of the task.

Thanks a lot!

Hi,
In the server side (the web services), change the namespace, by default the
name space is http://tempuri.org, change that to any conveient name you
like. That will solve the problem unless there is something else wrong.
Good luck :)

Beside following the steps you mentioned, we also need to change the
namespace of the web services, usinghttp://tempuri.orgis wrong. Also,
there is an option in the IE explorer that needs to be checked. The
option allow access data source accros domains needs to be checked.
Also, in order to pass data other than strings (float, integers,...), we
need to implement a serliziation class for these data types and compile
it
with the library.
Thanks for your kind reply, this was really a big headache!

Hi wedyan,

I had also the same problem but finally i got the solution. I have
some steps for you, just go through it.
1) Remove PropertyInfo from your code and add this like:

SoapObject request = new SoapObject(NAMESPACE,METHOD_NAME_TEMP);
// if you have 2 params in .net than add property this way. Suppose,
sum of two integers instead of PropertyInfo
request.addProperty(num, str1);
request.addProperty(b, str2);

2) Use HttpTransportSE instead of AndroidHttpTransport. and add
androidHttpTransport.setXmlVersionTag(?xml version=\1.0\ encoding=
\UTF-8\?);

3) To Display Result:
SoapPrimitive resultString = (SoapPrimitive)soapEnvelope.getResponse
();
System.out.println(resultString);
txtView.setText(Result is : +resultString);

Now, go through the above steps and also compare your application. I
hope you will find the solution. Let's hope.

Best Luck

[android-developers] Broadcast Receiver works sometimes/sometimes not.

2010-01-06 Thread Android Development

Hello,

I wish to listen to  android.intent.action.BOOT_COMPLETED.

However i am not getting the broadcast intent, if i specify
com.test.BootBroadcastReceiver in the manifest.

When i change this value to simply BootBroadcastReceiver, then i am getting
the broadcast intent.

receiver android:name=BootBroadcastReceiver android:enabled=true

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

 /receiver

My package in the manifest file is:

manifest xmlns:android=http://schemas.android.com/apk/res/android;
  package=com.test

and the BootBroadcastReceiver resides in this package.

What is the reason behind this ?

[android-developers] Re: Problems with the JavaBinder (!!! FAILED BINDER TRANSACTION!!!)

2010-01-06 Thread Moritzz

I tried it but it didn't change a thing. The images are pretty small
(just a few kilobyte as they are application icons) anyway. But I
figured something new out: If I continue to load them, I finally get
an OutOfMemoryException as mentioned in some sources and threads I
already read, including yours. Thing is, I have no clue how to find my
mistake(s) in the code and fix them. So here's some of my code:

First the function to get the images:

private Bitmap getIconFormServer(String url) {
Bitmap bm = null;
HttpClient httpClient = new DefaultHttpClient();
HttpGet getMethod = new HttpGet(url);
HttpResponse response;
getMethod.setHeader(Accept, application/json);
getMethod.setHeader(Content-type, application/json);
getMethod.setHeader(Accept-Encoding, gzip);
try {
response = httpClient.execute(getMethod);
InputStream inputStream = response.getEntity().getContent();
Header contentEncoding = response.getFirstHeader(Content-
Encoding);
if (contentEncoding != null  contentEncoding.getValue
().equalsIgnoreCase(gzip)) {
inputStream = new GZIPInputStream(inputStream);
}
bm = new BitmapDrawable(inputStream).getBitmap();
} catch (Exception e) {
return null;
} finally {
getMethod.abort();
inputStream.close();
}
return bm;
}

This one is called inside the service that's supposed to update the
widget. So I'm getting my pictures and update the widget out of the
service with

context = getApplicationContext();
thisWidget = new ComponentName(context, XWidget.class);
widgetManager = AppWidgetManager.getInstance(context);
widgetView = new RemoteViews(context.getPackageName(),
R.layout.widget);

and then later:

widgetView.setImageViewBitmap(id.getButton(), bitmap);
widgetManager.updateAppWidget(thisWidget, widgetView);


Cheers

Moritz

Also in his book Android wireless application development Shane Condor

[android-developers] Re: Broadcast Receiver works sometimes/sometimes not.

2010-01-06 Thread jwei512

I'm pretty sure it's because in the manifest, if the package is
com.test then when you declare Activities/Services/Receivers the
package name is already assumed... so if you do:

receiver android:name=.BootBroadcastReceiver
android:enabled=true

Then this is actually com.test.BootBroadcastReceiver, and if you do:

receiver android:name=com.test.BootBroadcastReceiver
android:enabled=true

Then I'm pretty sure the path is actually
com.test.com.test.BootBroadcastReceiver which obviously doesn't exist
in your project

But yes, please correct me if I'm wrong, but I'm pretty sure this is
why...

[android-developers] Re: how to clear activity stack in task

2010-01-06 Thread jwei512

Are you looking for a practical answer? Or was this more of a
theoretical thought experiment type of question?

If you want the practical answer, then I guess the simple thing to do
would be to kill Activity A in it's onActivityResult method (which
should be overridden since you are calling startActivityForResult on
Activity B). In other words, before B kills itself, do something like
setResult(RESULT_OK) and then kill B. Once this happens, it will
return to Activity A's onActivityResult method, and in there you can
have something like

if(resultCode == RESULT_OK) {
  finish();
}

And so at this point, Activity C is what your user should see, and
Activity A/B have been killed off, and so once you kill Activity C
your Activity stack is cleared and you're good to go.

Hope this is what you were looking for.

[android-developers] Protection Method to avoid an .apk being copied overall

2010-01-06 Thread Alex Corbi

Hi Developers,

First i explain you my situation:

I have just released my new App (Voice Alerts - more info:
http://49ers.es/corbi/voice-alerts), there is a demo and a full (paid)
version.

For promoting/publicity purposes i would like to send a copy of the
full version to a couple of people, so they get the fully functional
app without paying for it. My fear is that if i send them the .apk
without any protection means implemented, it could happen that they
can eventually upload the file to a server and made it available for
free overall.

How would you guys solve this situation?

I have 2 ideas runing on my head right know:

- is it possible to return the money to a user that buys the app
through the market, using google checkout? This solution should be
just great because i will not have to add extra lines on the code or
prepare an especial .apk for it. Just return the money but the app
stays in the phone and would get the updates and everything.

- is it possible to check programatically wich google acount (or other
mail account) is being user on a phone, so the app would be associated
with just one email account and will only work with that phone?

any other alternatives...

Greetings ,

Alex.

Make a separate version that disables itself after a period of time.

[android-developers] Re: Protection Method to avoid an .apk being copied overall

2010-01-06 Thread matt smith

The general response to this question I have seen is as follows :
 - spend time improving your app, not the copy protection - it will
get hacked anyway
 - storing gmail or ime numbers is against data protection act

Personally I feel everyone is entitled to try and protect their apps
and would take the dev's not the pirate's side, but beware of stepping
into a lion's den as I saw someone do before.

I would add that any attempt you make is likely to fail as google
checkout is the only viable mechanism of selling apps in volume and it
doesn't give any mechanisms to associate a purchased non-refunded
payment with an apk. Until Google does this, I think most other
attempts will be a waste of time.

[android-developers] Re: Motionevent problems - multitouch events give wrong coordinates

2010-01-06 Thread WoodManEXP

Colin,

Wow!

I am working on using multitouch for a game and remain equally
confused by similar behavior and will be anxious to see how this is
resolved. So far the answer has eluded me too, sigh...

Thanks for positing such a clear explain. Maybe a Google person will
get involved.

 OK, So I have been racking my brain to try to figure out what is going
 wrong here. I wanted to experiment with multi-touch, so I decided to
 add the controls for LunarLander to the touchscreen.

 Instead of adding buttons, I defined regions on the screen that when
 touched, would act like the buttons on the keyboard (for example, the
 gas fires as long as you press the screen in the area defined for the
 gas button, and stops firing when you release.)

 To do this, I added the onTouchEvent override to the LunarView class
 as follows:

    /**
      * Standard override to get Touch Screen Events.
      */
     @Override
     public boolean onTouchEvent(MotionEvent event) {
         return thread.doTouchScreen(event);
     }

 Then, I added a function to the LunarThread called doTouchScreen.  I
 also added variables to define the boundaries of the touch areas on
 the screen for the buttons The boundaries are defined as follows and
 placed in the variable declaration location of the LunarThread:

         //* Y boundary of left and right turn button **/
         private float TurnButton_Y;

         //* X Boundary of the fire Button (left side of button)
         private float fireButton_X;

         //* X boundary of left turn button **/
         private float leftTurnButton_X = 100;

         //* X boundary of right turn button **/
         private float rightTurnButton_X = 200;

 The doTouchScreen code is the following:

  boolean doTouchScreen(MotionEvent event) {

                 boolean handled = true;

                 synchronized (mSurfaceHolder) {

                   int numevents = event.getPointerCount();
                   int action = event.getAction();
                   int ptrId = event.getPointerId(0);

               if(numevents  1)
                  ptrId = (action  MotionEvent.ACTION_POINTER_ID_MASK)



 MotionEvent.ACTION_POINTER_ID_SHIFT;
                  action = action  MotionEvent.ACTION_MASK;

               int ptrIndex = event.findPointerIndex(ptrId);

               float X = event.getX(ptrIndex);
               float Y = event.getY(ptrIndex);

                 if(action == event.ACTION_DOWN || action ==
 event.ACTION_MOVE)
                 {
                         if(Y  TurnButton_Y)
                                 {
                                         if(X  leftTurnButton_X)
                                         {
                                                 mRotating = -1;
                                                 turnButtonID = ptrId;
                                         }
                                         else if (X  rightTurnButton_X)
                                         {
                                                 mRotating = 1;
                                                 turnButtonID = ptrId;
                                         }
                                         else if (X  fireButton_X)
                                         {
                                                 setFiring(true);
                                                 gasButtonID = ptrId;
                                         }

                                         handled =  true;
                     }
                         handled = true;
                 }
                 else if(action == event.ACTION_UP || action ==
 event.ACTION_CANCEL)
                 {

                         if(gasButtonID == ptrId)
                         {
                                 setFiring(false);
                                 gasButtonID = -1;
                                 handled = true;
                         }
                         if(turnButtonID == ptrId)
                         {
                                 mRotating = 0;
                                 turnButtonID = -1;
                                 handled = true;
                         }
                         handled = true;
             }

                 }
                 return handled;
         }

 During testing I found consistent problems when performing the
 following pattern:

 1) Touch finger 1 down on gas button area
 2) Touch finger 2 down on turn button area
 3) Lift finger 1 off of gas button
 4) Touch finger 1 back on to gas button

 The problem is that after performing this pattern, the gas button
 fails to work.  Lifting the gas button and then placing it down a
 third time causes the button to work again.  This is consistent every
 time I try this. Debugging yielded the following strange results:

 1) Finger 1 goes down at location X, Y.
      X = X
      Y = Y

[android-developers] Clicking a link in Browser initates a new Intent

2010-01-06 Thread Balder

I am working on an app that I want to be able to open links from eg.
an email app. I have an intent-filter that looks like this:

intent-filter
  action android:name=android.intent.action.VIEW /
  category android:name=android.intent.category.DEFAULT /
  category android:name=android.intent.category.BROWSABLE /
  data android:scheme=http /
  data android:scheme=https /
/intent-filter

Now, if I click a link in an email, I get the dialog where I can
choose whether to open the link with my app or with Browser. This is
all well and good, but I also get this dialog whenever I click a link
in the Browser app, or even enter a URL in the address field! I've
noticed that the Steel browser doesn't work like this; clicking a link
in Steel simply opens the link. Is there a way to circumvent this
behavior in the Browser app, yet still present my app as an option
when clicking links in email clients and the like?

Re: [android-developers] Problem in Accessing 2.9 MB Database from Apps

I had the same problem.
I provided a text file with the insert queries (one per line) in
res/raw, and, on first startup, populated a database.
This way you bypass the 1.1 MB limit (my DB is circa 3 MB, like yours).

I had to split the selects in two chunks (about 1000 each), because
decompressing them from the apk exceeded the allowed size.

Bye.

Re: [android-developers] Clicking a link in Browser initates a new Intent

2010-01-06 Thread Mark Murphy

 I am working on an app that I want to be able to open links from eg.
 an email app. I have an intent-filter that looks like this:

 intent-filter
   action android:name=android.intent.action.VIEW /
   category android:name=android.intent.category.DEFAULT /
   category android:name=android.intent.category.BROWSABLE /
   data android:scheme=http /
   data android:scheme=https /
 /intent-filter

That intent filter is evil.

 Now, if I click a link in an email, I get the dialog where I can
 choose whether to open the link with my app or with Browser. This is
 all well and good, but I also get this dialog whenever I click a link
 in the Browser app, or even enter a URL in the address field!

That's what you specified in the intent filter -- you claim to support
every HTTP(S) URL everywhere regardless of MIME type, host, or anything
else. That's why the intent filter is evil.

 Is there a way to circumvent this
 behavior in the Browser app, yet still present my app as an option
 when clicking links in email clients and the like?

Intent filters are agnostic to the sender of the Intent, so anything in
the system could send an Intent that your intent filter will match. Then,
if the sender uses Intent.createChooser(), like the Browser app does, you
will appear as a viable option.

Furthermore, you really need to more tightly constrain that intent filter,
so it is only going to be used for MIME types you actually will support,
or only from certain sites, or something. Look at the data element in
the SDK documentation:

http://developer.android.com/intl/fr/guide/topics/manifest/data-element.html

                  android:hint=This is a hint 
  android:inputType=textPassword
                  android:layout_width=wrap_content
  android:layout_height=wrap_content/EditText

  The hint is displayed with bigger/double spaces between the words.
  If I remove the inputType attribute it all goes back to normal.

  I couldn't find a known issue regarding this behavior.

  BTW- If you wonder why this is important (it isn't that much) try
  putting two EditText widgets one below the other and set the inputType
  of one of them to textpassword it doesn't look good.

  Any comments?

[android-developers] Re: Clicking a link in Browser initates a new Intent

 That's what you specified in the intent filter -- you claim to support
 every HTTP(S) URL everywhere regardless of MIME type, host, or anything
 else.

That is correct, yes.

 That's why the intent filter is evil.

Evil is a bit harsh, isn't it? :) After all, it's pretty much the
same filter used by Browser (with the omission of about: URIs)

  Is there a way to circumvent this
  behavior in the Browser app, yet still present my app as an option
  when clicking links in email clients and the like?

 Intent filters are agnostic to the sender of the Intent, so anything in
 the system could send an Intent that your intent filter will match. Then,
 if the sender uses Intent.createChooser(), like the Browser app does, you
 will appear as a viable option.

I guess this part is my actual problem. I can see why the email app
would invoke ResolverActivity, but why the Browser would do this for
every clicked link and every entered URL is unclear to me. As
mentioned, Steel doesn't do this. Setting Steel to the default URL
handler will therefore, in effect, render the Browser app unusable
since any click or address entry in Browser will be sent to Steel.

It seems like the answer to my question is no then?

 Furthermore, you really need to more tightly constrain that intent filter,
 so it is only going to be used for MIME types you actually will support,
 or only from certain sites, or something. Look at the data element in
 the SDK documentation:

Well, the MIME type of a HTTP(S) resource will be unknown until the
network resource is opened, won't it? For example when I click a link
in an email. Anyway, since text/html and application/xhtml+xml are
among the MIME types I'm interested in, I guess it wouldn't help me if
I did know the type beforehand; Browser would still pop up a chooser
that contained my app along with Browser itself.

[android-developers] StartActivityForResult

2010-01-06 Thread Business Talk

I am using ListActivities to drill down into a hierarchy; artist,
album and song. One activity per hierarchy. So, from the main
activity  I start the ArtistActivity with the StartActivityForResult
method and when the an artist is selected I call the

protected void onListItemClick(ListView l, View v, int position, long
id) {

setResult(Activity.RESULT_OK, results);
finish();

}

to return the results. Than the main activity receives results from
the ArtistsActivity in the onActivityResult method and starts the next
hierarchy’s activity, AlbumActivity, in the same way as the previous
activity, on so on. It works fine except that when calling finish
method the hierarchy activity is removed from the stack. So, it makes
it impossible to backtrack to the previous hierarchy since it’s not
there anymore. For example, I can’t backtrack from AlbumActivity to
the ArtistsActivity since it has been removed from the stack.  My
question is; is there any way to leave the hierarchy activities on the
stack?

This is not significantly different than on other platforms. For example,

 Set the adapter once, when you create the list.  Requery the list's
 cursor as needed.  If you use a cursor adapter you may never have to
 requery manually.

 Good luck!

[android-developers] scaling game images according display sizes

2010-01-06 Thread Andrea

Hi
I developed a game with the g1 in my mind. Now I want to support large
screen sizes but I don't want to add in the apk different images for
different screen sizes because now the apk is 3mb and when installed
trought market it became 6mb (due to protection on). If i have to
double the images to support new screens, the apk would be too heavy
(about 13mb, i think) so I'm wondering to know if scaling images at
runtime by myself (without compatibility mode) maybe the best way for
supporting larger screens. Someone tried this solution? Compatbility
mode does a great work in scaling images but it slows down drastically
the framerate (i think because the scale operation is made every time
an image is used/moved and not only once on the load of the image
itself).

Thanks

Instead of calling setResult()/finish() in a list item click,
startActivityForResult() the next level down in the hierarchy. Only the
leaf should call setResult()/finish() in a list item click. All branches
of the hierarchy should call setResult()/finish() in their
onActivityResult(), forwarding the leaf's result Intent along.

 I have no idea how you'd tell Windows that you are the default handler for
 http:// URLs...but only if they are launched from Outlook and not from

Well, to use the Windows analogy, I'd be happy to open links from
Thunderbird and MSN Messenger as well, but probably not Chrome or IE.
The Android browser is different in the respect that if you tell
Windows that you are the default handler for HTTP URLs, IE will still
be able to both open a web page and follow its links without launching
the newly set default browser. In fact, having a browser ask you which
app you want to open a web page in every time you click a link seems a
bit redundant. Oh well, seems like I'll need to figure out some not-
too-nasty hack.

[android-developers] Using an image in a listview

2010-01-06 Thread Patrick Plaatje

Hi all,

for my app i'm using a listview to display rss news articles. All goes
well, and the implementation is almost done. But when using my app,
i'm not really satisfied with the smoothness and user experience of
it. The main problem is that when i scroll through the listview, which
contains an image for each row in the listview, the scrolling isn;t
smooth, it executes the getview override every time. I already threw
out the holder startegy, as it slowed the scrolling...

any thoughts?

Thanx,

Patrick

I done a bit on authenticating using Google web toolkit about a year ago, it
might be slightly different when doing it through Android but I'd imagine it
would be fairly similiar

you can read about how I authenticated with GWT on my website here -
http://www.riad-donal-rafferty.com/portfolioGWT.html

Be aware that this isn't the most secure way to authenticate.

Also the code isn't formated on the website, you may want to copy and paste
it into an editor

Hope it helps

[android-developers] Re: Null pointer exception

2010-01-06 Thread JasonMP

That was it!  I took out the startManagingCursor() and it worked
fine.  My next question is what should I do to handle the life cycle
of my cursor?  Should I close it outside the switch statement?

On Jan 5, 5:41 pm, Vladimir vladimir.funti...@gmail.com wrote:
 What do you think about this:
 1. Cursor created in onContextItemSelected() is null (for some reason)
 2. Since its lifecycle is managed by the activity (startManagingCursor
 (c)), it tries to release it when the activity is stopped (when the
 new intent is launched)
 3. It doesn't expect managed cursor to be null and crashes (at
 android.app.Activity.performStop(Activity.java:3604))
 Does that make sense? I have little idea about how this cursor
 management works, but I would do the following:
 1. Try removing startManagingCursor() calls to see if these are
 related
 2. Double check if the cursor is null
 3. Take a look inside Android source and specifically Activity.java:
 3604
 Just a guess :)

 Is that a class from another of your files?  I guess I would wonder 
 if the

 causing some kind of loop.  I would grep for any reference to your

 suspect.

 In general, the below is kind of a side topic, to maybe help you with
 generic debugging.

 *Ok... the only thing I can think to really help you is to start 
 taking
 advantage of logging.  In your import list, I see you don't include 
 the
 logger code, so maybe you can give this a shot.

 1) in the import list

 import android.util.Log;

 2) and throughout your code

 Log.d( TAG, DebugText );

 where TAG is a string that is unique to you, and DebugText is 
 something
 useful to identify the part of the program you're interested in.

Thanks Mark, it will work. I was considering this approach. I was

activities. I thought I might have a need to reuse the activities in
other scenarios in which I might have to select the artists/albums/
songs only without drilling down the hierarchy. I will go with your

  to return the results. Than the main activity receives results from
  the ArtistsActivity in the onActivityResult method and starts the next
  hierarchy s activity, AlbumActivity, in the same way as the previous
  activity, on so on. It works fine except that when calling finish

  it impossible to backtrack to the previous hierarchy since it s not
  there anymore. For example, I can t backtrack from AlbumActivity to
  the ArtistsActivity since it has been removed from the stack.  My
  question is; is there any way to leave the hierarchy activities on the
  stack?

 Instead of calling setResult()/finish() in a list item click,
 startActivityForResult() the next level down in the hierarchy. Only the
 leaf should call setResult()/finish() in a list item click. All branches
 of the hierarchy should call setResult()/finish() in their
 onActivityResult(), forwarding the leaf's result Intent along.

 Hi folks,

 I'm running into some issues with input events and garbage collection,
 or more precisely object allocation.  I am creating a game and have
 pretty much got my head around the OpenGL environment.  I've digested
 all the relevant material I could find regarding performance, memory
 allocation etc (and watched the excellent presentation by Chris Pruett
 -http://code.google.com/events/io/2009/sessions/WritingRealTimeGamesAn...).
 I've pretty much eliminated any object allocations after initial setup
 from my game (which is still in its infancy), but I'm still getting a
 bunch of GC calls, like this:

 DEBUG/dalvikvm(52): GC freed 10398 objects / 880928 bytes in 139ms

 This is killing my frame-rate and creating a jittery experience, which
 is no good.  Running DDMS I see that the culprit isMotionEventand
 KeyEvent.  Allocations like:

 656     float[] 3       android.view.MotionEvent       init
 656     float[] 3       android.view.MotionEvent       init
 656     float[] 3       android.view.MotionEvent       init
 656     float[] 3       android.view.MotionEvent       init
 656     float[] 3       android.view.MotionEvent       init

 (there are many more, this is just a snapshot)

 It seems that every time aMotionEventis recorded, a float array is
 created?

 I am just using the onKeyDown event in the main Activity to broker the
 key event to my game thread.  I'm also sleeping (16ms) in this method
 call (as per Chris Pruett's recommendation) to save in excessive
 notifications.

 Is there something special I can do to eliminate these allocations?
 Perhaps there is an alternate way of obtaining key events and or
 trackball events? (which also are a cause of several allocations)

 Thanks in advance...

[android-developers] Broadcast receiver for ACTION_UP of the camera button

2010-01-06 Thread pablo

Hi

Samsung Galaxy, Android 1.5. I'm trying to detect when the user
releases the camera button. I have a receiver that gets the
ACTION_CAMERA_BUTTON intent and examines the EXTRA_KEY_EVENT that
comes with it,using the following code (in the onReceive() in the
receiver)

@Override
public void onReceive(Context context, Intent intent) {
String intent_action = intent.getAction();
 if (intent_action.equals(Intent.ACTION_CAMERA_BUTTON) ) {
abortBroadcast();
KeyEvent key = (KeyEvent) intent.getParcelableExtra
(Intent.EXTRA_KEY_EVENT);

if ( key.getAction() == KeyEvent.ACTION_DOWN )
Toast.makeText(context, press,
Toast.LENGTH_SHORT).show();
else if ( key.getAction() == KeyEvent.ACTION_UP )
Toast.makeText(context, release,
Toast.LENGTH_SHORT).show();
else if ( key.getAction() == KeyEvent.ACTION_MULTIPLE )
Toast.makeText(context, multi,
Toast.LENGTH_SHORT).show();
}
}

When I press the button, I only get the press popup.

Is this a limitation in the phone or in Android? Is there another way
to detect the release of the camera key?

[android-developers] Re: Nested TabWidget ?

2010-01-06 Thread NoraBora

Method 1.

tab content can be an activity.

so you can have another tabwidget (@android:id/tabs) in that activity.


Method 2.

You don't have to use TabActivity to use tabs.

All TabActivity does is to match tab widget to predefined ids such as
tabs, tabcontents.

Without using TabActivity, you can still match the ids and call
TabHost's setup() to add tabs.

Although I couldn't find the example that uses tabs without
TabActivity. I've done it once.

See http://developer.android.com/reference/android/widget/TabHost.html

Hi Brion,

thanks, i will certainly give that a try. But the funy thing is that
i'm actually not attaching that much data to my listview rows. I even
stripped the images from it and i still have some hickups when
scrolling. And it's indeed probably the getview method which tries to
attach the data to the view.

But as said i'll give the example a go and see if that helps. Many

[android-developers] Save a highscore-list to the internal memory or the sd-card?

2010-01-06 Thread Martin

Hi!

I am programming a game. How can I save a highscore-List to the
internal memory of the phone?

Or is it better to store highscore-lists to sd-card? If yes, how can I
do that?

Greetings, Martin

[android-developers] Performance issue: Dalvik VM is 20x slower than most modern Java VMs

2010-01-06 Thread Biosopher

I'm writing a processing intensive digital sound processing app
(requires numerous (50,000) Fast Fourier Transforms - FFT).  This
challenge led me to perform basic performance tests of Android running
on an HTC Hero.

The results show the Dalvik VM to be 20 times slower than a modern
JIT-enabled JVM running J2ME and 25-50 times slower than a C program
performing the same operations on a similarly powered mobile phone.

For example, this simple iteration over an empty method 2 million
times takes 1.4 seconds even though it doesn’t do anything.  The same
iteration is performed in milliseconds by a C program and about 100ms
on a modern JVM

public void performanceTest1() {
for (int i = 0; i  200; i++) {
emptyMethod();
}
}

private int emptyMethod() {
return 0;
}

Doing something a little more complex like calculating the imaginary
component of a complex conjugate 2 million times takes 3.2 seconds.
Again, this takes milliseconds on other mobile phones running J2ME or
C.

public void performanceTest2() {
for (int i = 0; i  200; i++) {
int a  = 5;
int b  = 5;
int c  = 5;
int x  = 5;
int y  = 5;

y = ((a  16) * ((c  16)  16)) + (((a  0X) * ((c 

16)  16))  16);
y = -y;
y  += ((b  16) * (c  16)) + (((b  0X) * (c  16)) 

16);
}
}

Has anyone else been able to overcome these performance issues of
Android?

[android-developers] Re: Maps API in paid App

2010-01-06 Thread Maps.Huge.Info (Maps API Guru)

WARNING: IANAL / IANAGE

If the Google Maps API terms are to be taken into account, then
publishing a paid app with a map could be considered a violation. Just
because your app hasn't been pulled doesn't mean a thing. I'm guessing
at least 50% of the apps in the market violate the market terms for
violation of copyrights (every sound board for instance), and they
aren't being pulled either. Does that mean they are in compliance or
does it mean that Google isn't proactive in enforcing their terms at
the moment?

According to definition, a commercial application is one that is
used for, connected with, engaged in, sponsored by or used in commerce
or commercial enterprises, such as AP News or Best Buy shopping. A
non-commercial application might be for a non-profit, a hobby site or
something along that line.

An application that requires payment to use is absolutely a non-free
use of the maps and is in violation of 9.1 of the Maps API TOS.

Then again, what do I know?

You'll have to use the NDK and write some native C code to do your

2010-01-06 Thread Piotr Buła

Did some googling and found a solution.

Looks like the problem is with the emulated SD card. In my case, the
1.5 AVD that failed had a virtual SD card defined when it was created
with old SDK. Deleting the AVD and creating it again solved the
problem. Also, create SD card images larger then 8 megs, or you'll get
the same error.

Hope this helps.

2010-01-06 Thread Maps.Huge.Info (Maps API Guru)

You're not testing to see if you get a null provider, also I'm not
sure asking to use POWER_LOW and ACCURACY_FINE will work as GPS uses a
lot of power.

I suggest dropping the POWER_LOW and testing provider for null.

Also, unless you need a very accurate fix, the wireless network
location service (ACCURACY_COARSE) is much faster, uses less power and
also works indoors, you might consider using that as well.

As a side note, you're not going to get a good fix using
getLastKnownLocation without first attaching a listener to the GPS.
The last known location might be 100 miles away, if the last time
location services were used was a while ago. I've found
getLastKnownLocation to be unreliable.

I've been thinking of writing a secret storage system for Android --
does such a thing already exist?  I've used Zetetic's open-source
Strip tool for many years on PalmOS, and found it handy, so I'd like
to have something like that on Android.

Ideally, I would use SQLite databases to store the info, but it seems
that there's no way to encrypt those database files.  This is a huge
security hole.  SD card storage of course can be compromised, but even
on-device storage is available to a sophisticated attacker who
actually has the physical phone.

I see that a ticket was opened about this in Feb 2008, but apparently
closed shortly thereafter with a somewhat short-sighted analysis of
the security problem.  Would it be futile to re-open such a ticket?
Does anyone else have a solution to this?

[android-developers] TimePicker widget

2010-01-06 Thread priyanjan

Hi All,
I am new at android. My concern is to increse the minutes in
TimePicker by 15 minute. If user clicks on '+'  button given in

in multiple of 15 . i.e., 15... then 30. then 45 and then 60.Is
there any way to achieve this functionality simply by using TimePicker
widget in our application???

[android-developers] Will native libs built with the NDK work with the Nexus One?

2010-01-06 Thread Francois Hamel

Basically is the ARMv7 instruction set somehow an extension of the
ARMv5 or is it completely different? I'd like to get started building
somewhat large components of my game in it since the JVM seems to be
slow as hell from what I've read.

And if anyone did something with it how did you manage to debug/step
into your native lib while debugging your application written in java?
Am I forced to build a Win32 application as well using my lib for
debug purposes?

Also, if I buy it, will the Market work for paid apps too? Currently

[android-developers] Geolocation in Browser works in 1.6 (Gears) but not 2.0 (HTML5/W3C) - Tested in emulator and real devices.

2010-01-06 Thread Ben Hedrington

I created this little Geolocation experiment site http://www.bctx.info/wx
it works great on my Android 1.6 (Magic, I/O Phone) it prompts the
user to share, returns lat, log and is snappy. 1.6 uses Gears for
this. I tried it on an up to date Droid and a 2.0 emulator image and
it detects the navigator.geolocation element (excellent!) and waits
for the user to share but no popup appears on the device and it cannot
proceed. Any thoughts?

The test site: http://www.bctx.info/wx

as reported before you can enable/disable component with the

the widget will be referenced in the widget menu on the home screen

and enable it at runtime there is not change in the widget menu.

what do i have to do to 'force' this change to the widget menu?

Hey!
I think I have the same problem, and I do not have any focusable

LinearLayout

   |
   +-- LinearLayout
   |
   +-- TextView
   |
   +-- TextView
   |
   +-- TextView

and the Main activity is like this:

code
public class Main extends Activity
{
ArrayListNode nodes;

/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState)
{
requestWindowFeature(Window.FEATURE_NO_TITLE);
super.onCreate(savedInstanceState);
setContentView(R.layout.main);

ArrayListNode nodes = new ArrayListNode();
nodes.add(new Node(My name, My text, 13:10, 0));

NodeRowAdapter nra = new NodeRowAdapter(this, nodes);

ListView listView1 = (ListView) findViewById
(R.id.ListViewNodes);
listView1.setOnItemClickListener(new OnItemClickListener() {

public void onItemClick(AdapterView? parent, View view, int
position, long id)
{
System.out.println (get onItem Click position=
+position);
}
});
listView1.setAdapter(nra);

 I have modified my firewall here to meet MS's recommendations for

 Does anyone else manage an exchange server and have access to these

I've developed an app that is using a map as part of the application
and adding locations to it. Users are asking me to add the possibility
to see these locations on the Maps application.

Do you know how I can create an customized layer for the Maps
application?

Thanks for your help

Nicolas

[android-developers] Re: Android Books?...

2010-01-06 Thread kylestew

There really aren't any good Android books out there. I bought two of
them and they are just poor copies of what Google wrote for
developers. If you want to build games you should look for books on
making games with open gl es. You should be able to find info on the
internet about any Android specific open gl implementation.

Good luck

[android-developers] How to get service state?

2010-01-06 Thread Coby

Hi!

I'm trying to get current service state of my phone (IN_SERVICE,
OUT_OF_SERVICE, EMERGENCY_ONLY, POWER_OFF). It can be easily fetched
with getState() method of ServiceState when a onServiceStateChanged
(ServiceState serviceState) callback is invoked:

public class ServiceStateListener extends PhoneStateListener{
@Override
public void onServiceStateChanged(ServiceState serviceState) {
switch(serviceState.getState()){
case ServiceState.STATE_IN_SERVICE:
Log.i(Listener, In Service);
break;
case ServiceState.STATE_EMERGENCY_ONLY:
Log.i(Listener, Emergency);
break;
case ServiceState.STATE_OUT_OF_SERVICE:
Log.i(Listener, Out Of Service);
break;
case ServiceState.STATE_POWER_OFF:
Log.i(Listener, Phone Off);
break;
}
}

But if you explicitly create a ServiceState object and try to get it's
state. It's always Out Of Service (returns 1), no matter what state
your phone is in right now:

@Override
public void onCreate() {
ServiceState serviceState = new ServiceState();
Log.i(onCreate, Integer.toString(serviceState.getState()));
}

I don't have much experience with Android. Any help is appreciated.

[android-developers] Question about emulator and accented character input

2010-01-06 Thread Daniel Sternbergh

I'm puzzled by the difference between the accented characters that are
available on a long keypreess on the soft keyboard that pops up within
the device in the emulator, and those which are available on a long
keypress on the soft keyboard in the emulator itself.  The behavior
that I see is that the device's soft keyboard presents a subset of the
options -- for example, the Latin IME offers 7 alternates for a but
the keyboard offers 9.

The characters that I'm particularly interested (vowel with macron) in
are found in the keyboard's larger set but not in the IME's subset,
but I haven't been able to find any information on why the IME
provides only a subset, and whether the larger set is accessible to
devices with a physical keyboard, only to those devices, and not to
devices with only the IME/soft keyboard.

[android-developers] Re: Using an image in a listview

What does your getView code look like. Are re-inflating your row view
every time it's called, are there multiple views for the rows etc?

 Hi all,

 for my app i'm using a listview to display rss news articles. All goes
 well, and the implementation is almost done. But when using my app,
 i'm not really satisfied with the smoothness and user experience of
 it. The main problem is that when i scroll through the listview, which
 contains an image for each row in the listview, the scrolling isn;t
 smooth, it executes the getview override every time. I already threw
 out the holder startegy, as it slowed the scrolling...

 any thoughts?

 Thanx,

[android-developers] How to delete applications from the Android simulator.

2010-01-06 Thread John Gaby

I know that this is probably a stupid question, but I am completely
new to Android development.  I have worked through a number of the
examples, and now have a bunch of apps on my simulated phone.  I would
like to remove some of those apps (to reduce the clutter), but cannot
figure out how to do it.  If I click on the app icon and hold down the
mouse button, the screen changes to the main screen, and there appears
to be a trash can at the bottom.  However, dragging the icon to the
trash can seems to have no effect.

Thanks.

[android-developers] OpenGL fixed point vs. floating point

2010-01-06 Thread Peter Eastman

OpenGL ES allows values to be specified in either fixed point or
floating point format, but I haven't been able to find any information
about how this is actually implemented on Android devices.  Are there
actually two different pipelines, one for fixed point and one for
floating point?  If so, what happens if you mix and match them, such
as specifying your matrix in floating point but your vertices in fixed
point?  Alternatively, does it implement everything with just one
format internally, and convert the other format to it as necessary?
If so, then you presumably get the best performance if you always
specify values in the internal format so as to avoid conversions.  How
then can I determine which format is used internally?

I notice that the Matrix and Visibility classes only accept floating
point values for matrices.  Should I interpret that as a
recommendation to use floating point for matrices?

Re: [android-developers] Re: Nexus 2.1 one sale, WHERE is the SDK!

2010-01-06 Thread David Sauter

 Reading the numerous N1 reviews over the last day, one recurring theme
 is (now that there's finally Android hardware to equal the iPhone) the
 app catalog is the major drawback to the platform. IOW, pissing off
 developers is the last thing Google should be doing right now.

Amusingly enough it's the defenses that Android has because it can
multitask that are killing high end development for it.  16MB heap
renders the phone just about useless for the high end stuff.

[android-developers] Re: scaling game images according display sizes

2010-01-06 Thread Andrea

Hi Robert, thanks for the reply.
Ok the images are loaded as Bitmaps (not drawable) and drawed on the
onDraw(Canvas c) method of a view. Inside that method I invalidate()
all the view. So the game runs as fast as it can. The game is using
dirty rects technique to redraw only the portions of the screen that
need to be changed. Here is the simply code structure:

//on a view
private void onDraw(Canvas c){

   //do staff

   invalidate();
}

if you need some other info, tell me it.

a.p.

  Hi
  I developed a game with the g1 in my mind. Now I want to support large

  double the images to support new screens, the apk would be too heavy
  (about 13mb, i think) so I'm wondering to know if scaling images at
  runtime by myself (without compatibility mode) maybe the best way for
  supporting larger screens. Someone tried this solution? Compatbility
  mode does a great work in scaling images but it slows down drastically
  the framerate (i think because the scale operation is made every time
  an image is used/moved and not only once on the load of the image
  itself).
