本人用alarmmanager设置了定时任务，但是锁屏的时候根本不会执行。查了大量资料，还是无法解决，有好的办法吗？(测试手机:华为相关代码如下：

if (Build.VERSION.SDK_INT >= 19) {
                            mAlarmManager.setExact(AlarmManager.RTC_WAKEUP,
                                    course.getStartTime().getTimeInMillis(),
                                    vibrationPI);
                            mAlarmManager.setExact(AlarmManager.RTC_WAKEUP,
                                    course.getEndTime().getTimeInMillis(),
                                    normalPI);
                        } else {
                            mAlarmManager.set(AlarmManager.RTC_WAKEUP,
                                    course.getStartTime().getTimeInMillis(),
                                    vibrationPI);
                            mAlarmManager.set(AlarmManager.RTC_WAKEUP,
                                    course.getEndTime().getTimeInMillis(),
                                    normalPI);
                        }

public class SetVibrationService extends IntentService {
    private static final String NAME = "SetVibrationService";
    private static final int NOTIFICATION_ID = 1;
    public SetVibrationService() {
        super(NAME);
    }
    @Override
    protected void onHandleIntent(Intent intent) {
        AudioManager audioManager =
                (AudioManager) getSystemService(Context.AUDIO_SERVICE);
        audioManager.setRingerMode(AudioManager.RINGER_MODE_VIBRATE);
        audioManager.setStreamVolume(AudioManager.STREAM_MUSIC, 0, 1);
        NotificationUtil.
                sendNotification(this, NOTIFICATION_ID, R.string.vibrate_service_notification_text);
        Log.d("ApplicationLog", "VibrateService" + new Date());
    }
}

public class SetNormalService extends IntentService {
    private static final String NAME = "SetNormalService";
    private static final int NOTIFICATION_ID = 2;
    public SetNormalService() {
        super(NAME);
    }
    @Override
    protected void onHandleIntent(Intent intent) {
        AudioManager audioManager =
                (AudioManager) getSystemService(Context.AUDIO_SERVICE);
        audioManager.setRingerMode(AudioManager.RINGER_MODE_NORMAL);
        audioManager.setStreamVolume(AudioManager.STREAM_MUSIC, 2, 1);
        NotificationUtil.
                sendNotification(this, NOTIFICATION_ID, R.string.normal_service_notification_text);
        Log.d("ApplicationLog", "NormalService" + new Date());
    }
}

解决方案

本人用过华为pad 他的闹钟最低间隔时间好像是5秒用的是audioManager.setRepeating 同样的代码在小米手机上可行（锁屏睡眠后正常运行，本人设置的是1秒一次）

你这个不会执行本人估计是还没执行到定时那去就睡眠了睡眠后线程，服务都挂起了估计是一直没有执行到开启闹钟那里。
