受講しているクラスのグループ プロジェクトに取り組んでいますが、Alarm Manager がインテントを繰り返し起動しない理由がわかりません。ソース コードを上から下まで調べましたが、この問題の原因を特定することはできません。

誰でも修正を推奨できますか？（あるいは出発点？）

// AlarmManager を使用してサービスを開始します

    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

私は同様の問題を抱えており、おそらくあなたにも当てはまります（提供したコードはナビゲートするのがかなり難しいため、わかりにくいです）。

私の問題は、同等と評価されたマネージャーに複数のインテントを適用すると、そのインテントの以前の適用が無効になることでした。等価性の意味については、 http://developer.android.com/reference/android/content/Intent.html#filterEquals(android.content.Intent)を参照してください。例として、URI domy://thing を使用するスケジュールを作成し、インテントごとに異なるエクストラを使用しました (毎回異なる引数で同じアクションを起動する必要があります)。エクストラは同等にカウントされないため、アラームが互いに上書きされていました。

これを回避するために、アラームのキューを別のファイルに保存し、1 つが発火したときに次のアラームを一番上からポップしてマネージャーに入れました。多分それはあなたを助けるでしょう。

更新:公開されている例はありませんが、これを試してください(トリガーはURIと起動する必要がある時間を含む単純なオブジェクトであり、scheduleDbはSQLiteOpenHelperを拡張するクラスです):

  /**
   * 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;
  }

それが役立つことを願っています
