我正在尝试使用Google Play游戏服务制作简单的游戏，但是我无法登录到Google Play游戏。
我收到了这个错误：
登录失败。请检查您的网络连接并重试。
我有MainActivity和三个片段（MainFragment、GameFragment和ResultFragment）。
MainFragment是主菜单的片段，在那里用户有按钮可以点击来开始游戏。
授权？
我已经在Google Play开发者控制台中链接和授权了我的游戏的SHA-1。
由于我使用Android Studio，我的包名看起来像是：aplikacijezaandroid.thebuttonchallenge，并且我在Google Play开发者控制台上添加了两个应用程序版本。
因此，我有com.aplikacijezaandroid.thebuttonchallenge和aplikacijezaandorid.thebuttonchallenge。
应用程序ID？
我将应用程序ID和排行榜ID添加到strings.xml中，并将meta标签添加到Android清单中。
我在AndroidManifest.xml中添加了Internet权限。
测试？
我使用物理设备从Android Studio测试和调试应用程序，当然在Google Play开发者控制台中添加了自己的Gmail作为测试用户。
这是我的AndroidManifest.xml
