Android ShowleaderboardsUI（）；不起作用

我一直在努力将我的应用程序与google play服务连接起来，我的用户在连接应用程序时遇到了一个问题，但在这之后，我制作了一个带有“ShowleaderboardsUI（）；”的按钮，单击后什么也没有发生。我已将电子邮件添加到测试组

using UnityEngine;
using UnityEngine.UI;
using GooglePlayGames;
using UnityEngine.SocialPlatforms;

public class AchievmentManager : MonoBehaviour
{

    private bool IsConnectedToGoogleServices;

   void Start()
    {
        PlayGamesPlatform.DebugLogEnabled = true;
        PlayGamesPlatform.Activate();
        IsConnectedToGoogleServices = false;
        ConnectToGoogleServices();
    }

 public bool ConnectToGoogleServices()
    {
        if (!IsConnectedToGoogleServices)
        {
            {
                Social.localUser.Authenticate((bool success) =>
                    {
                        IsConnectedToGoogleServices = success;
                    });
            }
        }
        return IsConnectedToGoogleServices;
    }

    public void ToLeaderboard()
    {
        if (Social.localUser.authenticated)
        {
            Social.ShowLeaderboardUI();
        }
        else
        {
            Debug.Log("Unable to connect google play services");
        }
    }
}

您应该尝试将此添加到android mainfest：

 <activity android:name="com.google.games.bridge.NativeBridgeActivity" android:theme="@android:style/Theme.Translucent.NoTitleBar.Fullscreen" />

您可以在Assets/Plugins/Android/AndroidMainfest.xml中创建自定义mainfest
