DllNotFoundException：gpg

Question

我和一个朋友正在用Unity for Android开发游戏，我们想在Google Play游戏服务中加入一些排行榜，但无法使登录生效。

我们使用Google Play游戏插件的最小示例项目中的脚本MainGui进行登录。 当我们按下验证按钮时，它会一直说“正在验证”：

if (!Social.localUser.authenticated)
        {
            // Authenticate
            mWaitingForAuth = true;
            mStatusText = "Authenticating...";
            Social.localUser.Authenticate((bool success) =>
            {
                mWaitingForAuth = false;
                if (success)
                {
                    mStatusText = "Welcome " + Social.localUser.userName;
                }
                else
                {
                    mStatusText = "Authentication failed.";
                }
            });
        }

在logcat中查看，有一个错误：

E/Unity: DllNotFoundException: gpg

我们一直在寻找时间，并尝试了其他答案，并删除了插件并将其重新添加到项目中，检查了api密钥，是从其他计算机上构建的，等等。
