Hi,
I wrote an Android widget with alarmmanager as updating process.
Sometimes i've got a nullpointer exception. But all objects are
initialized...
public void UpdateWidget(Context con)
{
//Log.d("berlinClock", "UpdateWidget="+i);
RemoteViews views=new
RemoteViews(con.getPackageName(),R.layout.widgetlayout);
Calendar c = Calendar.getInstance();
int h = c.get(Calendar.HOUR_OF_DAY);
int m = c.get(Calendar.MINUTE);
ComponentName thisWidget = new ComponentName(con,widget.class);
//update views on remoteView
// GOT NULLPOINTER EXEPTION IN FOLLOWING LINE (96)
views.setImageViewResource(R.id.wha1, R.drawable.cgrau);
views.setImageViewResource(R.id.wha2, R.drawable.cgrau);
...
}
Here is the Stacktrace:
