Alright guys, I finally got time to fix this problem once and for all :)

I created more methods for the provider instead of doing everything in onUpdate, one important method needed:

    public static PendingIntent buildButtonPendingIntent(Context context) {
      Intent intent = new Intent();
      intent.setAction("COM_FLASHLIGHT");
      return PendingIntent.getBroadcast(context, 0, intent, PendingIntent.FLAG_UPDATE_CURRENT);
    }

And this method is called through the receiver when the widget is clicked using the code below:

private void turnFlash(Context context) {
    RemoteViews views = new RemoteViews(context.getPackageName(), R.layout.appwidget_layout);
    views.setOnClickPendingIntent(R.id.imageButton,       WidgetProvider.buildButtonPendingIntent(context));
}

That is all, no more hiccups!
