AppWidget PendingIntent在啓動器重新啓動後不起作用

我有一個AppWidget，其中有兩個待定目標。他們大部分時間都在工作，但過了一段時間他們停止了迴應。我唯一能指出的一點是，在啓動器重新啓動之後它們已經癱瘓了，也就是我使用了Launcher Pro，並且有時候會調整設置並重新啓動它。之後，他們根本不工作。AppWidget PendingIntent在啓動器重新啓動後不起作用

這裏是我的onRecieve()和onUpdate()方法：

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); 
} 
}

我看了一下把意圖的服務，但已經嘗試和失敗。任何幫助表示讚賞。

什麼是調用`super.onUpdate（）;`？根據源http://androidxref.com/4.4.4_r1/xref/frameworks/base/core/java/android/appwidget/AppWidgetProvider.java#113，它不會執行任何操作。 – faizal 2014-07-16 06:19:17

`appWidgetManager.updateAppWidget（）`不需要在每個小部件的循環中調用。它接受一個整數數組。所以你可以簡單地多次調用`appWidgetManager.updateAppWidget（appWidgetId，top）`而不是`appWidgetManager.updateAppWidget（appWidgetId，top）`。 – faizal 2014-07-16 06:48:50

正如我寫的here你應該只產生一個RemoteView的實例。
