報警管理器不會反覆執行

Question

我正在爲我正在參加的課程開展一個小組項目，我們似乎無法弄清楚爲什麼我們的報警管理器不會反覆激發意圖。我們從上到下挑選了源代碼，似乎無法隔離此問題的根源。

任何人都可以推薦一個修補程序嗎？ （？或者一個起點）

//使用AlarmManager

啓動服務

Calendar cal = Calendar.getInstance(); 
    cal.add(Calendar.SECOND, 10); 
    Intent intent = new Intent(Rules.this, LMW.class); 
    PendingIntent pintent = PendingIntent.getService(Rules.this, 0, intent, 
      0); 
    AlarmManager alarm = (AlarmManager) getSystemService(Context.ALARM_SERVICE); 
    alarm.setRepeating(AlarmManager.RTC_WAKEUP, cal.getTimeInMillis(), 
      7 * 1000, pintent); 


    // Start 2nd service using AlarmManager 
    Intent intent2 = new Intent(Rules.this, KillTimer.class); 
    PendingIntent pintent2 = PendingIntent.getActivity(Rules.this, 0, intent2, 
      0); 
    AlarmManager alarm2 = (AlarmManager) getSystemService(Context.ALARM_SERVICE); 
    alarm.setRepeating(AlarmManager.RTC_WAKEUP, cal.getTimeInMillis(), 
      120 * 1000, pintent2); // here

Answer 1

我有類似的問題，也許它適用於你（很難說，因爲你提供的代碼很難導航）。

我的問題是，將多個意圖應用到經理評估爲相等，覆蓋了該意圖的以前的應用程序。請參閱http://developer.android.com/reference/android/content/Intent.html#filterEquals(android.content.Intent)以瞭解我的意思是等同。作爲一個例子，我有一個使用URI domy：//東西的時間表，每個意圖都有額外的變化（我需要每次都用不同的參數激發相同的動作）。附加功能不等同，所以我的報警被對方覆蓋。

爲了解決這個問題，我在一個單獨的文件中存儲了一個警報隊列，當一個人發射時，從頂部彈出下一個，並將其放入管理器中。也許這會幫助你。

UPDATE： 沒有例子公開可見的，但試試這個（觸發器是包含一個URI，它需要被解僱時的簡單對象，scheduleDb是擴展SQLiteOpenHelper類）：

/** 
    * Pops the next trigger off the queue, adds it to the alarm manager, and 
    * stores it in the DB in case we need to cancel it later. 
    */ 
    private void scheduleNextTrigger() { 
    Log.d(TAG, "Popping next trigger off queue"); 
    Optional<Trigger> nextTrigger = scheduleDb.getNextTrigger(); 

    if (!nextTrigger.isPresent()) { 
     Log.d(TAG, "Trigger queue is empty"); 
     return; 
    } 
    Trigger trigger = nextTrigger.get(); 
    Log.d(TAG, "Scheduling new trigger " + trigger); 
    PendingIntent operation = createPendingIntent(trigger); 
    long timestamp = trigger.getTimestamp(); 

    // Ensure the next item is in the future 
    if (timestamp > clock.currentTimeMillis()) { 
     Log.v(TAG, "Found valid trigger: " + trigger); 
     alarmManager.set(AlarmManager.RTC_WAKEUP, timestamp, operation); 
    } 
    scheduleDb.setScheduledTrigger(trigger); 
    } 

    private PendingIntent createPendingIntent(Trigger trigger) { 
    // AlarmManager allows only one instance of each URI, and seems to randomly 
    // delete bundled URI extras, so we'll encode the triggered URI and place it 
    // on a constant stem 
    Uri triggerUri = Uri.parse(TRIGGER_URI + "?" + Uri.encode(trigger.getUri())); 

    Intent triggerIntent = new Intent(Intent.ACTION_VIEW, triggerUri); 
    triggerIntent.setFlags(Intent.FLAG_ACTIVITY_NO_HISTORY); 
    Log.d(TAG, "Created trigger intent " + triggerIntent); 

    PendingIntent operation = PendingIntent.getService(this, 0, triggerIntent, 0); 

    return operation; 
    } 

希望這有助於
