AppWidget PendingIntent not working after Launcher

问题:

I have an AppWidget with 2 pending intents. They work most of the time, but after a while they stop responding. Only thing I have been able to pinpoint is that they are crippled after a Launcher restart, i.e. I use Launcher Pro, and sometimes fiddle with settings and have to restart it. After that they don't work at all.

Here are my onRecieve() and onUpdate() methods:

   public void onReceive(Context context, Intent intent)
{
    super.onReceive(context, intent);
    String action = intent.getAction();
    if(action.equals("android.tristan.widget.digiclock.CLICK"))
    {
        PackageManager packageManager = context.getPackageManager();
        Intent alarmClockIntent = new Intent(Intent.ACTION_MAIN).addCategory(Intent.CATEGORY_LAUNCHER);

        String clockImpls[][] = {
                {"HTC Alarm Clock", "com.htc.android.worldclock", "com.htc.android.worldclock.AlarmClock" },
                {"Standar Alarm Clock", "com.android.deskclock", "com.android.deskclock.AlarmClock"},
                {"Froyo Nexus Alarm Clock", "com.google.android.deskclock", "com.android.deskclock.DeskClock"},
                {"Moto Blur Alarm Clock", "com.motorola.blur.alarmclock",  "com.motorola.blur.alarmclock.AlarmClock"}
        };

        boolean foundClockImpl = false;

        for(int i=0; i<clockImpls.length; i++) {
            String vendor = clockImpls[i][0];
            String packageName = clockImpls[i][1];
            String className = clockImpls[i][2];
            try {
                ComponentName cn = new ComponentName(packageName, className);
                ActivityInfo aInfo = packageManager.getActivityInfo(cn, PackageManager.GET_META_DATA);
                alarmClockIntent.setComponent(cn);
                foundClockImpl = true;
            } catch (NameNotFoundException e) {
                Log.d(LOGTAG, "Error," + vendor + " does not exist");
            }
        }

        if (foundClockImpl) {
        Vibrator vibrator = (Vibrator) context.getSystemService(Context.VIBRATOR_SERVICE);
        vibrator.vibrate(50);
        final RemoteViews views = new RemoteViews(context.getPackageName(), layoutID);
        views.setOnClickPendingIntent(R.id.TopRow, PendingIntent.getActivity(context, 0, new Intent(context, DigiClock.class).setFlags(Intent.FLAG_ACTIVITY_NEW_TASK), PendingIntent.FLAG_UPDATE_CURRENT));
        AppWidgetManager.getInstance(context).updateAppWidget(intent.getIntArrayExtra(AppWidgetManager.EXTRA_APPWIDGET_IDS), views);
        alarmClockIntent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
        context.startActivity(alarmClockIntent);       
   }
    }
}

        public void onUpdate(Context context, AppWidgetManager appWidgetManager, int[] appWidgetIds) {
super.onUpdate(context, appWidgetManager, appWidgetIds);
    context.startService(new Intent(UpdateService.ACTION_UPDATE));
    context.startService(new Intent(context, ScreenUpdateService.class));
    final int Top = appWidgetIds.length;
    final int Bottom = appWidgetIds.length;
    for (int i=0; i<Top; i++)
    {
    int[] appWidgetId = appWidgetIds;
    final RemoteViews top=new RemoteViews(context.getPackageName(), layoutID);
    Intent clickintent=new Intent("android.tristan.widget.digiclock.CLICK");
    PendingIntent pendingIntentClick=PendingIntent.getBroadcast(context, 0, clickintent, 0);
    top.setOnClickPendingIntent(R.id.TopRow, pendingIntentClick);
    appWidgetManager.updateAppWidget(appWidgetId, top);
}
for (int i=0; i<Bottom; i++)
{
    int[] appWidgetId = appWidgetIds;
    RemoteViews bottom=new RemoteViews(context.getPackageName(), layoutID);
    Intent clickintent=new Intent("android.tristan.widget.digiclock.CLICK_2");
    PendingIntent pendingIntentClick=PendingIntent.getBroadcast(context, 0, clickintent, 0);
    bottom.setOnClickPendingIntent(R.id.BottomRow, pendingIntentClick);
    appWidgetManager.updateAppWidget(appWidgetId, bottom);
}
}

I have read about putting the intents in a service, but have tried and failed. Any help is appreciated.

As I've written here you should only produce a single instance of the RemoteView.
