android深度睡眠对广播有什么影响吗,为什么WakefulBroadcastReceiver不能将我的设备从深度睡眠中唤醒？...

我正在使用唤醒服务的WakefulBroadcastReceiver唤醒我的设备。该服务启动一个活动，并在最后通知WakefulBroadcastReceiver结束作业。我做了一个日志文件，我什么都看不到。当我解锁设备时，几秒钟后，活动即开始。当我设置闹钟时，为什么不做？为什么WakefulBroadcastReceiver不能将我的设备从深度睡眠中唤醒？

Manifest包含BroadcastReceiver和Service声明和WAKE_LOCK权限。

这里是WakefulBroadcastReceiver：

public class AlarmBroadcastReceiver extends WakefulBroadcastReceiver {

public AlarmBroadcastReceiver() {

Logging.logToFile("Construct broadcast receiver");

}

@Override

public void onReceive(Context context, Intent intent) {

Intent service = new Intent(context, AlarmService.class);

startWakefulService(context, service);

Logging.logToFile("Started wakeful broadcast receiver");

}

}

这里是服务类：

public class AlarmService extends IntentService {

public AlarmService() {

super("AlarmService");

Logging.logToFile("Started intent service");

}

@Override

protected void onHandleIntent(Intent intent) {

Logging.logToFile("Handle intent service");

Intent service = new Intent(this, WakeUpActivity.class);

service.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK | Intent.FLAG_ACTIVITY_CLEAR_TASK);

startActivity(service);

AlarmBroadcastReceiver.completeWakefulIntent(intent);

}

@Override

public void onDestroy() {

super.onDestroy();

Logging.logToFile("Destroy intent service");

}

}

这里是我的日志：

编辑：这是我如何设置闹钟：

Intent intent = new Intent(SmartClockActivity.this, AlarmBroadcastReceiver.class);

PendingIntent pendingIntent = PendingIntent.getBroadcast(SmartClockActivity.this, 0, intent, 0);

AlarmManager alarmManager = (AlarmManager) getSystemService(ALARM_SERVICE);

alarmManager.set(AlarmManager.RTC_WAKEUP, cal.getTimeInMillis(), pendingIntent);

+1

请包括你如何设置报警 –
