关于android：重写onNewToken并从Firebase错误中获取令牌


Overriding onNewToken and getting tokens from firebase errors

我想找回我的令牌，而我正在做很多示例
在FirebaseMessagingService上，我有这个

1
2
3
4
5
 @Override
    public void onNewToken(String token) {
        super.onNewToken(token);
        Log.e("Refreshed token:",token);
    }

我得到了错误

Method does not override method from it's superclass

当然super.onNewToken(token)有错误

cannot resolve method

在我的mainactivity上，我在OnCreate()里面有这个

1

FirebaseInstanceId.getInstance().getInstanceId().addOnSuccessListener( MyActivity.this,  new OnSuccessListener<InstanceIdResult>() {
     @Override
     public void onSuccess(InstanceIdResult instanceIdResult) {          
           String newToken = instanceIdResult.getToken();    
     }
 });

我得到的错误是：

Cannot resolve getInstanceId()

无法解析InstanceIdResult

不能
解析getToken()

并且Method不会覆盖它的方法

superclass
