当设备处于待机状态时,android tv无法接收fcm消息

我们知道,电视没有系统栏,所以我只发送数据信息,当信息应用程序在前台、后台甚至不运行时,它就会工作。但当我按“电源”键(电源即时开启)时,设备将进入待机模式(str standby),我可以保证消息已成功发送:

{
 "to" : "xxx",
 "collapse_key" : "tv",
 "priority": "high",
 "content_available":true,
 "data" : {
     "body" : "wake up"
 }
}

{
    "multicast_id": xxx,
    "success": 1,
    "failure": 0,
    "canonical_ids": 0,
    "results": [
        {
            "message_id": "xxx"
        }
    ]
}

我可以看到日志:

broadcast intent callback: result=CANCELLED forIntent { act=com.google.android.c2dm.intent.RECEIVE flg=0x10000000 pkg=com.tcl.fcmapp (has extras) }

当电视处于待机状态时,我通过以下方法唤醒设备:

/**
 * Called when message is received.
 *
 * @param remoteMessage Object representing the message received from Firebase Cloud Messaging.
 */
@Override
public void onMessageReceived(RemoteMessage remoteMessage) {
    Log.d(TAG, "From: " + remoteMessage.getFrom());

    // Check if message contains a data payload.
    if (remoteMessage.getData().size() > 0) {
        Log.d(TAG, "Message data payload: " + remoteMessage.getData());
        wakeUpScreen();
    }
}

private void wakeUpScreen() {
    PowerManager pm = (PowerManager) getSystemService(Context.POWER_SERVICE);
    @SuppressLint("InvalidWakeLockTag") PowerManager.WakeLock wakeLock = pm.newWakeLock
            (PowerManager.SCREEN_BRIGHT_WAKE_LOCK, "LiveTV");
    wakeLock.setReferenceCounted(false);
    try {
        wakeLock.acquire();
    } catch (Exception e) {
        e.printStackTrace();
    }
}

我读过有关FCM的文档,上面说FCM支持唤醒设备,那么我的使用方式有什么问题吗?
