android - Android：警报管理器和意图过滤器不起作用

Question

所以我设置了一个触发意图的警报。我还有一个广播监听器，它有一个意图过滤器来捕捉该意图，但由于某种原因它不起作用。我不确定问题出在哪里（发送或接收或两者兼而有之）。

发送代码：

Intent reminderIntent = new Intent();
reminderIntent.setAction(INTENT_ACTION_ALARM); //INTENT_ACTION_ALARM is String "intent_myaction_alarm"

PendingIntent pendingIntent = PendingIntent.getBroadcast(context, 0, reminderIntent, 0);

Calendar time = Calendar.getInstance();
time.setTimeInMillis(System.currentTimeMillis());

alarmManager.set(AlarmManager.RTC, time.getTimeInMillis(), pendingIntent);

接收代码：

IntentFilter intentFilter = new IntentFilter();
intentFilter.addAction(INTENT_ACTION_ALARM);

alarmReceiver = new BroadcastReceiver() {
  @Override
  public void onReceive(Context context, Intent intent) {
          // DO SOMETHING
   } 
};

context.registerReceiver(alarmReceiver, intentFilter);
