我正在使用IntentService准备闹钟，并在其中使用setAlarmClock来设置闹钟。 IntentService始终在适当的时间运行并设置警报（图标将显示），但警报将在100次中工作约99次。当一个警报失败时，每次警报都会发生类似的Intent在您完全关闭应用程序之前会失败（requestsCode中PendingIntent的内容无关紧要。无论如何，在预定的闹钟时间之前的微秒，这称为：
09-19 16:10:59.996 1374-2126/? V/AlarmManager: Expired Alarm result :4
09-19 16:11:00.046 1374-2126/? D/VirtualScreenPolicy: applyVirtualScreenAttrs attrs=VirtualScreenAttrs{mDisplayId=0, mBaseDisplayId=0, mBaseActivity=false}

09-19 16:11:00.116 23354-23354/? I/CocktailBarPositionManager: updateAlphaScreenPosition position is dirty 0
如果有效，最终会调用Activity生命周期方法（onCreate，onResume，onStart ...）：
09-19 16:45:00.048 1366-2124/? V/WindowManager: addAppToken: AppWindowToken{d09214481 token=Token{fb31868 ActivityRecord{8afbf8b u0 com.simplyneededapps.ridealarm/.MapAlarm t2738}}} to stack=2 task=2738 at 1
如果它没有运行Activity生命周期方法永远不会被调用，那就是：
09-13 10:05:00.379 1366-2124/? I/WindowManager: Screenshot max retries 4 of Token{d83f8b2 ActivityRecord{b762abd u0 com.simplyneededapps.ridealarm/.MainActivity t2491}} appWin=Window{6dec0a u0 d0 com.simplyneededapps.ridealarm/com.simplyneededapps.ridealarm.MainActivity} drawState=4

在我的IntentService中：
@Override
protected void onHandleIntent(Intent intent) {
//about 200 lines setting up the alarm
AlarmManager alarmMgr;
PendingIntent pIntent;
alarmMgr = (AlarmManager) context2.getSystemService(Context.ALARM_SERVICE);
Intent intent2 = new Intent(context2, MapAlarm.class);
intent2.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK | Intent.FLAG_ACTIVITY_CLEAR_TASK);
intent2.putExtra("id",id)
pIntent = PendingIntent.getActivity(context2, (int) id, intent2, PendingIntent.FLAG_UPDATE_CURRENT);
if(Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
AlarmManager.AlarmClockInfo alarmClockInfo = new AlarmManager.AlarmClockInfo(next,pIntent);
alarmMgr.setAlarmClock(alarmClockInfo,pIntent);
}else{
alarmMgr.setExact(AlarmManager.RTC_WAKEUP, next, pIntent);
}
stopService(intent);
}
有没有办法始终确保始终调用onCreate或至少onResume，无论如何？我仍然无法确定直接原因所以任何和所有的帮助将不胜感激！
