Question

又是我即使我的应用程序已经连接到Firebase，我似乎也找不到它的令牌。任何形式的帮助将不胜感激。

下面是代码

Answer 1

在您的onNewToken(String)类上覆盖FirebaseMessagingService：

@Override
public void onNewToken(String token) {
    super.onNewToken(token);
    // Your code here
}

Answer 2

onNewToken仅在生成新令牌时被调用。 Firebase不会在每次打开应用程序时创建新令牌。在您的MainActivity的onCreate中添加

FirebaseInstanceId.getInstance().getInstanceId().addOnSuccessListener(this,  new OnSuccessListener<InstanceIdResult>() {                    
            @Override
            public void onSuccess(InstanceIdResult instanceIdResult) {
                  String token = instanceIdResult.getToken();
                  Log.d("MyFirebaseToken", token);

            }});

在Logcat Android Studio上找不到令牌
