Re: [android-developers] Avoiding FAILED BINDER TRANSACTION error when updating lots of widget bitmaps
Hi, I have the same problem using setImageURI. The problem seems to be worse than just a scaling issue. It seems that some vendors have fixed this bug for some of their devices. I have a HTC Sensation that doesn't scale the image set through setImageURI. All other devices I know do. For me the only workaround for this is to measure the applied scaling by instantiating an ImageView that consumes a sample image from my ContentProvider. The extra scaling for the images that has to be applied can be calculated by comparing the ImageViews size to the original size of the sample image. Fixing this bug wouldn't change anything for the next 2 years as most of us developers want to support not only the last generation of Android devices ;) Greetings Michael Am Freitag, 17.

Re: [android-developers] Avoiding FAILED BINDER TRANSACTION error when updating lots of widget bitmaps
I think I found the problem...and it looks like it's an Android bug.
Drawable.createFromStream() doesn't take as parameter a Resources object,
and later it calls Drawable.createFromResourceStream() passing 'null' as
the Resources parameter.
From my understanding the resources are then used to ensure that the
drawable will set its target density correctly, but by being 'null' some
default density is used.

Re: [android-developers] Avoiding FAILED BINDER TRANSACTION error when updating lots of widget bitmaps
Hi, I'm encountering exactly the same problem,however I'm not getting my failed bind transaction immediately, it looks like it happens after a certain amount of widget updates. The initial size is small enough to succeed and the image size is small ( I'm always updating a small single image ~ 4K). In order to to conserve resources I'm not inflating my widget on each update instead I'm using the same RemoteViews only updating the image, for example: // Use cached value. RemoteViews returnValue = mRemoteViewCreator.getRemoteView(); returnValue.setImageViewBitmap(R.id.imgTextWithImage, myImg); ... appWidgetManager.updateAppWidget(thisWidget, returnValue); Couple of questions: 1. Does it make sense to update the widget this way ? Is it really faster ? 2. How do I know what is size that is transferred through the IPC mechanism ?

Re: [android-developers] Avoiding FAILED BINDER TRANSACTION error when updating lots of widget bitmaps
It is actually 1MB. The most common reason for this error is a too large IPC. As a quick test, you could try removing half the bitmaps or so and see if it works. If so, the issue is almost certainly an IPC that is too large. If that is the case, you just need to reduce the amount of data being sent over.

Binder data size limit is 512K, IIRC, so it should be enough for the update. Are you sure the failed transaction is not caused by bad data in RemoteViews (references to views that don't exist, etc.) that cause the remote side (Launcher) to crash? What are the other methods to push a bitmap into a widget? Anything I could search for? ImageView can grab images from a Uri, and supports content:// and file:// style Uris. -- Kostya Thanks for your help!

Re: [android-developers] Avoiding FAILED BINDER TRANSACTION error when updating lots of widget bitmaps
Hi Kostya / Dianne,
Thanks for the replies. As Dianne suggested, removing half the bitmaps does
indeed make it work.
I can't really reduce the amount of bitmaps, so I am trying to use the
setImageURI on ImageView. Unfortunately I am getting permission denied
errors.
Here is the test code I used: -
File file = new File(context.getFilesDir().getAbsolutePath()
+ /skins/Minimal/flight_on.png);
if (file.exists()){
Uri uri = Uri.fromFile(file);
Log.i(LOGTAG, uri.toString());
views.setUri(R.id.buttonSound, setImageURI, uri);
}
The file *does* exist and I get the following log message: -
08-01 17:19:20.304: INFO/WidgetTest(4563):
file:///data/data/sirocco.widgets/files/skins/Minimal/flight_on.png
I didn't think I would have permission problems with the widget's own files.
Is there a problem with accessing these files from a widget (actually a
private service class within the widget)?
Thanks again for your help
All the best,
Ash

Re: [android-developers] Avoiding FAILED BINDER TRANSACTION error when updating lots of widget bitmaps
Those files aren't be accessed by you, they are being opened by another app
(the launcher) when it applies your RemoteViews to the widget it is
displaying.

Re: [android-developers] Avoiding FAILED BINDER TRANSACTION error when updating lots of widget bitmaps
Ah ok, I copy the files over into the skins directory in my configuration activity. I currently use normal java.io.FileOutputStream objects, should I be using context.openFileOutput with MODE_WORLD_READABLEhttp://developer.android.com/reference/android/content/Context.html#MODE_WORLD_READABLE set? -- You received this message because you are subscribed to the Google Groups Android Developers group.

Re: [android-developers] Avoiding FAILED BINDER TRANSACTION error when updating lots of widget bitmaps
Thanks Kostya and Dianne, setUri works as expected. I had to create the files using context.openFileOutput. Unfortunately that means I loose the ability to use directories. I can't see a Java way to set permission on files, it can be done with native methods, but that seems like overkill. I'll do some more googling. Thanks again for the help, I was worried that this problem might have been a show-stopper. Ash -- You received this message because you are subscribed to the Google Groups Android Developers group.

Re: [android-developers] Avoiding FAILED BINDER TRANSACTION error when updating lots of widget bitmaps
Well, there is File.setReadable, which is supposed to be able to change the permissions, but I've never tried it myself 01.08.2011 22:05, Ash McConnell пишет: Thanks Kostya and Dianne, setUri works as expected.
