如果活动被杀死，警报manager不起作用

Question

我有一个使用用户输入的日历(存储在对象中(的日历的警报器，我的目标是从本日历中进行schelude通知，如果应用程序运行所有内容都很好，但是如果它运行良好，则被扫除了通知不会出现的恢复应用程序。我的代码是：

Intent intent = new Intent(getApplicationContext(), EventReciver.class);
PendingIntent pendingIntent = PendingIntent.getBroadcast(this,0, intent,0);
Calendar calendar = Calendar.getInstance();
Calendar horaInicial = materiaBuffer.getHoraInicial(); //Take Calendar from materiaBuffer object
calendar.set(Calendar.HOUR_OF_DAY, horaInicial.get(Calendar.HOUR_OF_DAY));
calendar.set(Calendar.MINUTE, horaInicial.get(Calendar.MINUTE));
pendingIntent = PendingIntent.getBroadcast(this, i, intent, PendingIntent.FLAG_UPDATE_CURRENT);
alarmManager.set(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(), pendingIntent);

在AndroidManifest中，我只是更改：

<receiver android:name=".etc.EventReciver" android:process=":remote"></receiver>

我的EventReciver：

public class EventReciver extends BroadcastReceiver{
  @Override
  public void onReceive(Context context, Intent intent) {
      Log.i("Lauri", "EventReciver");
      // I removed the code for the notification, it works fine
  }
}

任何人可以帮忙吗？

我在lolipop上对其进行了测试。此代码正常运行，甚至应用程序也没有运行

Calendar calendar = Calendar.getInstance();
calendar.set(Calendar.HOUR_OF_DAY, 10);
calendar.set(Calendar.MINUTE, 27);
calendar.set(Calendar.SECOND, 0);
AlarmManager alarmManager = (AlarmManager) getSystemService(Context.ALARM_SERVICE);
Intent intent = new Intent(this, AlarmReceiver.class);
PendingIntent pendingIntent = PendingIntent.getBroadcast(this, 0, intent, PendingIntent.FLAG_UPDATE_CURRENT);
alarmManager.set(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(), pendingIntent);

在maifest

中

<receiver
  android:name=".AlarmReceiver"
  android:enabled="true"
  android:exported="true" />

接收器类

public class AlarmReceiver extends BroadcastReceiver {
@Override
public void onReceive(Context context, Intent intent) {
    System.out.println("Alarm Received");
    Toast.makeText(context, "Alerm Received", Toast.LENGTH_SHORT).show();
    NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(context)
            .setSmallIcon(R.mipmap.ic_launcher)
            .setPriority(NotificationCompat.PRIORITY_HIGH)
            .setContentTitle("Alarm")
            .setContentText("This code works!")
            .setAutoCancel(true);
    NotificationManager notificationManager =
            (NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);
    notificationManager.notify(0, notificationBuilder.build());
 }
}
