通知的警报管理器工作不正常

Question

我在Android中使用了报警管理器来显示一些通知，但它不能正常工作。

我的活动代码是：

Intent i = new Intent(this, AlarmBroadcastReceiver.class);
PendingIntent pendingIntent = PendingIntent.getBroadcast(this, 0, i, 0);
AlarmManager alarmManager = (AlarmManager)this.getSystemService(Context.ALARM_SERVICE);
alarmManager.cancel(pendingIntent);
alarmManager.setExact(AlarmManager.RTC_WAKEUP, System.currentTimeMillis() + (int) (10*60 * 1000),
pendingIntent);

15分钟后接收通知的代码是：

AlarmManager am = (AlarmManager) context.getSystemService(Context.ALARM_SERVICE);
Intent intent = new Intent(context, AlarmBroadcastReceiver.class);
PendingIntent pi = PendingIntent.getService(context, 0, intent, 0);
am.cancel(pi);
am.setExact(AlarmManager.ELAPSED_REALTIME_WAKEUP,
SystemClock.elapsedRealtime() +
(int) ( 5*60 * 1000), pi);

在使用服务时使用这种类型的AlarmManager，而不需要更改getBroadCast的getService。有时接收器不呼叫，当应用程序在后台时，也会在一些设备中产生问题

Intent intent = new Intent(myContext, SetAlarmService.class);
intent.putExtra("salah",i);
intent.putExtra("repeat",HowManyTimeRepeatAlarm);
PendingIntent pendingIntent = PendingIntent.getService(
myContext, i, intent, 0);
AlarmManager alarmManager = (AlarmManager) myContext.getSystemService(ALARM_SERVICE);
// alarmManager.cancel(pendingIntent);
alarmManager.setRepeating(AlarmManager.RTC_WAKEUP, reset_cal.getTimeInMillis(),60000 * 2 ,
pendingIntent);
