应用程序在后台时未调用Firebase onMessageReceived

@Override
public void onMessageReceived(RemoteMessage remoteMessage) {
    if (remoteMessage.getData().size() > 0) {
        // 处理数据消息
        String message = remoteMessage.getData().get("message");
        Log.d(TAG, "Message data payload: " + message);
    }
}

public class MyFirebaseMessagingService extends FirebaseMessagingService {
    @Override
    public void onMessageReceived(RemoteMessage remoteMessage) {
        if (remoteMessage.getData().size() > 0) {
            // 处理数据消息
            String message = remoteMessage.getData().get("message");
            Log.d(TAG, "Message data payload: " + message);
        }
    }
}

public class MyJobService extends JobService {
    @Override
    public boolean onStartJob(JobParameters params) {
        // 处理后台任务
        return false;
    }

    @Override
    public boolean onStopJob(JobParameters params) {
        return false;
    }
}
