FirebaseMessagingService onMessageReceived() not executing

Question

我刚开始使用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。

以下是我的火力基础消息服务

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)

应用程序接口：

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

页眉：

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

身体：

{
"to": "<Device FCM token>",
"notification": {
"title": "Demo tittle",
"body": "Demo body",
"mutable_content": true,
},
"data": {
"url": "<media image url>",
"dl": "<deeplink action>"
}
}
