GcmListenerService客户端通知

Question

我正在尝试使用gcm在Android设备上推送通知。到目前为止，我已经向gcm注册并向我的后端发送了必要的信息，以便向构建200响应的gcm服务器发送帖子请求。除了客户端接收消息之外，所有步骤都已合并。我收不到消息。这里显示的是我的gcm监听器类：

import com.google.android.gms.gcm.GcmListenerService;

public class MyGcmListenerService extends GcmListenerService {

    public static final int MESSAGE_NOTIFICATION_ID = 435345;

    private static final String TAG = "MyGcmListenerService";

    @Override
    public void onMessageReceived(String from, Bundle data) {
        String message = data.getString("message");
        Log.d(TAG, "From: " + from);
        Log.d(TAG, "Message: " + message);

        sendNotification(from,message);

    }

    private void sendNotification(String title, String body) {
        Context context = getBaseContext();
        NotificationCompat.Builder mBuilder = new NotificationCompat.Builder(context)
                .setSmallIcon(R.mipmap.ic_launcher).setContentTitle(title)
                .setContentText(body);
        NotificationManager mNotificationManager = (NotificationManager) context
                .getSystemService(Context.NOTIFICATION_SERVICE);
        mNotificationManager.notify(MESSAGE_NOTIFICATION_ID, mBuilder.build());
    }

}
