[android-developers] Re: How many threads can be created or how to avoid thread leak
This almost sounds like it should be a Service. The thread will only
run when you're Activity is running (basically) and isn't guaranteed
to be kept around once the Activity is cleaned up. You may want a
Service running that can handle this and then you'll have much more
control over it. Will you be handing incoming messages the same way?

[android-developers] Re: save image in Database
I handled this by saving the image to the ContentProvider android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI and then saving the created URI to the database along with my item.

[android-developers] Re: ImageButton caching images when using Uri
Sorry to talk t myself on this thread, but in case anyone else runs
into this problem in 1.0R1, the current workaround is to set the
ImageURI to null and then back to the URI after saving the image.

No one else has seen anything like this? Is there a way to enter this
as a bug against the Android codebase? I haven't actually seen the
open source part of this yet (I'd actually try and fix it if it was

[android-developers] ImageButton caching images when using Uri
I'm seeing some caching problems when using an ImageButton with a Uri
and I'm not sure if there's a flag that needs set somewhere or not.
I'm using the button to add an icon to an item in one of my
applications, exactly like it's being used for the Contact application
(which I don't think the source is available for). I'm using the CROP
trick seen in this application:
http://code.google.com/p/apps-for-android/source/browse/trunk/Photostream/src/com/google/android/photostream/ViewPhotoActivity.java
Specifically, I'm calling the image picker and then the crop like so:
protected OnClickListener cmdIconListener = new OnClickListener() {
// @Override
public void onClick(View arg0) {
Intent i = new
Intent("android.intent.action.GET_CONTENT");
i.setType("image/*");
startActivityForResult(i, AddTea.ADD_ICON);
}
};
protected void onActivityResult(int requestCode, int resultCode,
Intent data){
// See which child activity is calling us back.
switch (requestCode) {
case AddTea.ADD_ICON:
// This is the standard resultCode that is sent back if the
// activity crashed or didn't doesn't supply an explicit
result.
if (resultCode != RESULT_CANCELED){
Intent i = new Intent("com.android.camera.action.CROP");
i.setClassName("com.android.camera",
"com.android.camera.CropImage");
i.setData(data.getData());
Log.d(TAG, "path: " + data.getData().getPath());
i.putExtra("noFaceDetection", true);
i.putExtra("outputX", iconWidth);
i.putExtra("outputY", iconHeight);
i.putExtra("aspectX", iconWidth);
i.putExtra("aspectY", iconHeight);
i.putExtra("scale", true);
if(iconUri == null){
ContentValues values = new ContentValues();
values.put(android.provider.MediaStore.Images.Media.TITLE, name + "
Icon");
values.put(android.provider.MediaStore.Images.Media.BUCKET_ID,
"STeaP_Tea_Timer_Icons");
values.put(android.provider.MediaStore.Images.Media.BUCKET_DISPLAY_NAME,
"STeaP Tea Timer Icons");
iconUri =
getContentResolver().insert(android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI,
values).toString();
}
i.putExtra("output", Uri.parse(iconUri));
startActivityForResult(i, CROP_ICON);
}
break;
case AddTea.CROP_ICON:
if (resultCode != RESULT_CANCELED){
Log.d(TAG, "Data String: " + iconUri);
showIconButton(iconUri);
}
default:
break;
}
}
protected void showIconButton(String iconUri){
if(iconUri != null){
ImageButton iconField = (ImageButton)
findViewById(R.id.iconButton);
Log.d(TAG, "iconUri: " + iconUri);
iconField.setImageURI(Uri.parse(iconUri));
iconField.invalidate();
}
}
So if the item doesn't have an icon, set one in the ContentProvider
and save the iconUri. If it does, just overwrite it with the new
cropped image.
This works fine if the item never had an icon. It shows in the
ImageButton when the Activity returns. However, if the item already
had an icon, my Activity still shows the old icon, even though it was
overwritten. It seems that if the ImageButton gets the same Uri back,
even if I wrote a new image to it, it doesn't redraw, even if I tell
it to invalidate(). If I relaunch my Activity, the new image shows up
just like I expected. Funny enough, the Pictures application doesn't
see any images I created until I restart the emulator, which also
doesn't seem ideal!
So, is there anyway to handle this caching of the Uri? I seems like
the ContentProvider should be doing this when I write a new image to
it, but it doesn't seem to be. Also, before anyone suggests, I tried
deleteing the entry in the ContentProvider and making a new one and
that seems to partially work. It partilly works because, if the Uri
we get back it new, the view does refresh with this new Uri. However,
if the icon was the last picture to be saved to the ContentProvider,
say item 10, then the ContentProvider will delete item 10 and the
reuses 10 as the next id! So I'm back where I started and the
ImageButton shows the old icon.
Any help in kicking the ContentProvider of ImageButton into shape
would be appreciated.

[android-developers] Re: Test Location Providers in 1.0
That looks to be the case. It never made sense to me that we would have TestProvider code all through the app anyway. To test Location aware apps now, don't do anything special in your code (code it like you would for a real production application), but in Eclipse, open the Emulator Control view to send GPS lat and long. The docs say you can use a 'geo' app in the tools folder in the SDK, but it doesn't seem to exist yet. http://code.google.com/android/toolbox/apis/lbs.html On Sep 24, 5:21 am, Guillaume Perrot <[EMAIL PROTECTED]> wrote: > I was wondering too, I had to disable this function from my > application... > It seems we can only use DDMS or telnet to simulate location now. > > On 24 sep, 08:34, Reto Meier <[EMAIL PROTECTED]> wrote: > > > The ability to create and configure mock location providers that was > > added in Beta 0.9 doesn't seem available in 1.0. > > > Has this functionality been moved / renamed or has it been dropped > > entirely for version 1?
