我无法使用setExact（）重复设置AlarmManager

Question

我尝试使用setExact设置重复的AlarmManager。在活动中：

AlarmManager alarmManager = (AlarmManager) getSystemService(Context.ALARM_SERVICE);
Intent intent = new Intent(this, AlarmReceiver.class);
intent.setAction(ACTION_ALARM_RETRY);
PendingIntent sender = PendingIntent.getBroadcast(this, 0, intent, PendingIntent.FLAG_CANCEL_CURRENT); 
alarmManager.setExact(AlarmManager.RTC_WAKEUP, 7000, sender);`

在我的行动之后接收器中我有：

public void onReceive(Context context, Intent intent){
  //Here are my operations...
  AlarmManager alarmManager = (AlarmManager) context.getSystemService(Context.ALARM_SERVICE);
  Intent intent = new Intent(context, AlarmReceiver.class);
  intent.setAction(ACTION_ALARM_RETRY);
  PendingIntent sender = PendingIntent.getBroadcast(context, 1, intet, PendingIntent.FLAG_CANCEL_CURRENT); 
  alarmManager.setExact(AlarmManager.RTC_WAKEUP, 7000, sender);
}

但它一直重复，没有最模糊的停顿...... 求救！
