... which is in turn caused by a crash:

That is, updateAppWidget starts writing the RemoteViews object into a
Parcel, and crashes. Obviously the onUpdate() never returns, thus the ANR.
This runs on a separate thread, as can be seen further in the stack trace:
07-14 10:30:36.796: ERROR/AndroidRuntime(12077): at
com.hyves.android.widget.HyvesWidgetService.run(HyvesWidgetService.java:

07-14 10:30:36.796: ERROR/AndroidRuntime(12077): at
java.lang.Thread.run(Thread.java:1096)
Either it's really a threading problem, or else some data related to
RemoteViews is null (such as updateViews.setTextViewText(R.id.xxx,
null), or even the RemoteViews object itself is null). The latter one
should be easy to check by stepping through in the debugger.

Hmm yeah,.. im trying to make a simple widget now and adding more
stuff.
However maybe this output from LogCat also helps:
07-14 15:57:58.845: ERROR/ActivityManager(59): ANR in

07-14 15:57:58.845: ERROR/ActivityManager(59): Reason: Broadcast of

This should only happen if onUpdate() of your AppWidgetProvider is
taking too long. This may be tied to some of the funky thread locking
you're trying to do.
