Re: [android-developers] AppWidgets Disappearing from list in ICS
Hi Kostya,
Sorry for the late reply, it has been a hectic holiday period.
I couldn't get it to cause any problems in the emulator or any warnings on
my Android 2.2 device (Motorola Defy)
I got the user to send me a log file using a logfile capture app. There
was one exception of interest: -

Re: [android-developers] AppWidgets Disappearing from list in ICS
Yep, the user has just replied that he has a Galaxy Nexus and it doesn't have an SD card of course :( Can anyone think of another reason why the Widgets are being removed from the list when deleted from the homescreen? He says that the application still appears in the list of apps, so he isn't accidentally uninstalling. I'm a bit stuck on this one. Thanks!

Re: [android-developers] AppWidgets Disappearing from list in ICS
Ok, the user has responded to me with: - Ok I got the update then I did this added a clock removed that clock went back to widgets, icon for clock still there got as far as tapping add widget got Unfortunately, Launcher has stopped. clock widget now missing from widget list So then i tried rebooting the phone, clock widget still missing So I went through the same process with the bar widget but at the point where it stops I remembered to click Report So for some reason my widgets are causing the Launcher to crash (or the launcher is bugged), has anyone ever caused the launcher to crash when adding widgets? I've asked him which launcher he is using, but I suspect its the default Nexus launcher. I'll do some more googling armed with this extra info, but if it rings any bells with anyone please let me know :) All the best, Ash -- You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Possible to get AppWidget Height?
Hi Folks, I've found that for some Launchers my AppWidgethttps://market.android.com/details?id=sirocco.widgets doesn't format quite correctly as they squash the AppWidgets by 10 or so pixels (to add a page indicator) - e.g. Samsung Galaxy 2 and Sony Experia Arc. They must not provide the same amount of space (even if you consider device independent pixels) as all units use dp. Therefore I need a way to determine the height of an AppWidget. Is there a way?

Re: [android-developers] Android Widget update problem
You need to create a pending intent which will send an event to your widget,
then handle that event in your widget
Intent intent = new Intent(context, MightyToggleWidget.class);
intent.setAction(MY_HANDLE_BUTTON_EVENT_NAME);
PendingIntent pendingIntent = PendingIntent.getBroadcast(context, 0, intent,
0);
views.setOnClickPendingIntent(button, pendingIntent);
This will make the MY_HANDLE_BUTTON_EVENT_NAME event to be broadcast.
Now you need to handle this event in your AppWidgetProvider implementation
...To do this you need to tell Android O/S that your AppWidgetProvider will
handle the event, you do this by adding an entry in the intent-filter
section like so:-
action android:name=MY_HANDLE_BUTTON_EVENT_NAME /
Now you need to actually handle the event. You need to override
AppWidgetProvider's onReceive like so: -
@Override
public void onReceive(Context context, Intent intent) {
super.onReceive(context, intent);
if
(intent.getAction().equals(MY_HANDLE_BUTTON_EVENT_NAME){
doSomething();
}
}
I hope this helps!
All the best,
Ash

[android-developers] Offsetting position of a View in a AppWidget
I am creating an AppWidget that allows users to skin the widget and download from a list of widgets online. I would like to allow skinners to offset the position of the icons vertically. I initally tried calling offsetTopAndBottom on the LinearLayout that holds the icons, this is not allowed as its not supported with RemoteViews. I then had an idea of using 2 Views inside a LinearLayout (on top and below the icon Layout) to squash the icons towards the bottom (if the height of the top layout was set to 0). When I tried to set the height of these views: - views.setInt(R.id.iconMarginTop, setMinimumHeight, offset); it also complained that it wasn't supported with RemoteViews Any ideas what I could do to acheive this offset?

[android-developers] Re: App Widget stops responding to input after all instances are removed and another added
I have found the problem. The onEnabled event gets triggered at the start when the first widget is added. The onDisabled event gets triggered when the last widget is removed, but the onEnabled event does not get triggered when you try to add another first widget. I had code that was similar to the examples in those events. This resulted in the packagemanager unregistering my AppWidgetProvider from receiving these events For more explanation: - http://stackoverflow.com/questions/6917415/app-widget-stops-responding-to-input-after-all-instances-are-removed-and-another Hope this helps some googlers!

[android-developers] App Widget stops responding to input after all instances are removed and another added
I am having trouble when I add a one or more instances of my widget to the
home screen, remove them all, then add another.
Here is the code I use to set the onClick intent for each button (button
is a resource)
protected void matchButtonToAction(Context context, RemoteViews views,
String action, int button) {
Intent intent = new Intent(context, MightyToggleWidget.class);
intent.setAction(action);
PendingIntent pendingIntent = PendingIntent.getBroadcast(context, 0,
intent, 0);
views.setOnClickPendingIntent(button, pendingIntent);
}
This only happens when I remove *ALL* instances and add one. If I add 2,
remove 1 and add 1 it still works.
It is still receiving and reacting to events (such as wifi status changing
or battery events).
Any ideas what could be causing this?
Thanks!
Ash

[android-developers] Avoiding FAILED BINDER TRANSACTION error when updating lots of widget bitmaps
Hi Folks, I am coming across an error when I am updating my RemoteViews in my AppWidget. !!! FAILED BINDER TRANSACTION !!! This is caused because all the changes to the RemoteViews are serialised (e.g. setInt and setImageViewBitmap ). The bitmaps are also serialised into an internal bundle. Unfortunately this bundle has a very small size limit. I cannot use setImageResource as I am hoping to allow the user to download skins for the widget. Can anyone recommend a workaround for this problem? I am already using a new RemoteViews object for each instance of the widget, but a single instance contains too many updates.

Re: [android-developers] Avoiding FAILED BINDER TRANSACTION error when updating lots of widget bitmaps
Hi Kostya, It's not that the single bitmap is too large, it's that I'm updating quite a few bitmaps. The biggest bitmap in PNG form (a lot smaller I know) is only 4KB. I am updating 14 ImageViews in each update. Is there any way to split the update for each widget instance somehow? What are the other methods to push a bitmap into a widget?

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
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.
