这是登录活动代码 我收到一个错误 找不到符号类 FirebaseInstanceIdService 我附上一张图片供参考

这是我最后一年的项目，它是一个基于聊天的应用程序 由于这个过程，我无法生成 APK 但 Gradle 同步成功。

【问题讨论】：

FirebaseInstanceIdService 已弃用。你应该使用FirebaseMessagingService

这能回答你的问题吗？ FirebaseInstanceIdService is deprecated

【参考方案1】：

开发人员被 FirebaseInstanceIdService 弃用的问题所困扰，那么现在该怎么办？

FirebaseInstanceIdService

这个类已被弃用。 赞成在FirebaseMessagingService 中覆盖onNewToken。实施后，可以安全地删除此服务。 这意味着无需使用 FirebaseInstanceIdService 服务来获取 FCM 令牌。您可以安全地移除 FirebaseInstanceIdService 服务

现在我们需要@Override onNewToken()在“FirebaseMessagingService”中获取Token。

示例代码：

    public class MyFirebaseMessagingService extends FirebaseMessagingService 

        @Override
        public void onNewToken(String s) 
            super.onNewToken(s);
            Log.e("NEW_TOKEN",s);
        

        @Override
        public void onMessageReceived(RemoteMessage remoteMessage) 
            super.onMessageReceived(remoteMessage);
        
     

在androidManifest.xml

    <service
            android:name=".MyFirebaseMessagingService"
            android:stopWithTask="false">
            <intent-filter>
                <action android:name="com.google.firebase.MESSAGING_EVENT" />
            </intent-filter>
    </service>

Get Token in your Activity : .getToken(); 也被弃用，如果你需要在你的 Activity 中获取令牌然后使用如下：

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

         
     );

我希望你能在这里得到你的解决方案。

使用 onComplete(@NonNull Task task) 怎么样？
