我正在使用喚醒服務(wù)的WakefulBroadcastReceiver喚醒我的設(shè)備。該服務(wù)啟動一個活動，并在最后通知WakefulBroadcastReceiver結(jié)束作業(yè)。我做了一個日志文件，我什么都看不到。當(dāng)我解鎖設(shè)備時，幾秒鐘后，活動即開始。當(dāng)我設(shè)置鬧鐘時，為什么不做？為什么WakefulBroadcastReceiver不能將我的設(shè)備從深度睡眠中喚醒？

Manifest包含BroadcastReceiver和Service聲明和WAKE_LOCK權(quán)限。

這里是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");

}

}

這里是服務(wù)類：

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");

}

}

這里是我的日志：

編輯：這是我如何設(shè)置鬧鐘：

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

請包括你如何設(shè)置報警 –

@DavidMedenjak，完成。 –
