java - FirebaseMessagingService onMessageReceived() 未执行

Question

我刚刚开始使用 Firebase Cloud Messaging，并在 Manifest 中设置了所有依赖项、Firebase 服务及其服务标签。

从控制台发送消息时，会检测到目标用户，但应用程序不会收到通知。 所以我在 onMessageReceived() 上设置了一个断点。但它并没有被激发。

下面是我的 firebase 消息服务

public class MyFirebaseMessagingService extends FirebaseMessagingService {
private static final String TAG = "MyFirebaseMessagingServ";

@Override
public void onMessageReceived( RemoteMessage remoteMessage) {
    super.onMessageReceived(remoteMessage);
    String notificationBody = "";
    String notificationTitle = "";
    String notificationData = "";

    try{

        notificationData = remoteMessage.getData().toString();
        notificationTitle = remoteMessage.getNotification().getTitle();
        notificationBody = remoteMessage.getNotification().getBody();

    }
    catch (NullPointerException e){
        Log.e(TAG, "onMessageReceived: NullPointerException: " + e.getMessage() );

    }

    NotificationHelper.displayNotification(getApplicationContext(), notificationTitle, 
    notificationBody);
    Log.d(TAG, "onMessageReceived: data: " + notificationData);
    Log.d(TAG, "onMessageReceived: Notification body : " + notificationBody);
    Log.d(TAG, "onMessageReceived: notification title: " + notificationTitle);
}

if you are using firebase terminal you will face the issue so you can use notification API (use data message)

API:

https://fcm.googleapis.com/fcm/send

标题:

"Content-Type": "application/json",
"Authorization": "key=<Server_key>"

正文:

{
    "to": "<Device FCM token>",
    "notification": {
      "title": "Demo tittle",
      "body": "Demo body",
      "mutable_content": true,
      },

   "data": {
    "url": "<media image url>",
    "dl": "<deeplink action>"
      }
}
