The code in Launcher looks up the widget info object by the widget id. Does
your code properly handle that?
Here is my code from a widget config activity:
Intent resultValue = new Intent();
resultValue.putExtra(AppWidgetManager.EXTRA_APPWIDGET_ID, mAppWidgetId);
setResult(RESULT_OK, resultValue);
finish();
Where mAppWidgetId is initialized inside onCreate:
Intent intent = getIntent();
Bundle extras = intent.getExtras();
if (extras != null) {
mAppWidgetId = extras.getInt(AppWidgetManager.EXTRA_APPWIDGET_ID,
AppWidgetManager.INVALID_APPWIDGET_ID);
}
FWIW, I can't get your widget to crash on a Galaxy Nexus with 4.0.1, tried
both the switcher bar and the clock, but I did get a bunch of these in the
logcat when creating the clock:
