我正在尝试按照本指南https://developers.google.com/games/services/training/signin实施Google Play服务登录但是当活动开始时，我收到此错误：

如果您的包名或app_id不可用，则会抛出错误！
当您想要实施Google Play服务时，您必须在Google Play中创建应用，获取app_id并指定包名称; 如果没问题，那么您将更改您的应用程序的软件包名称是您自己的软件包名称（与您在Developer Console中注册的名称相同）就像com.example。*。 您将修改res / values / ids.xml或其他文件中的app_id;
你可以获得更多帮助 https://github.com/playgameservices/android-samples 部分＆＃34;修改ID，编译和运行＆＃34;非常有用。
祝你好运！答案 1 :(得分：1)
确保您在清单中使用了正确版本的APP_ID。
对于访问GameHelper.CLIENT_APPSTATE的客户，您需要
<meta-data android:name="com.google.android.gms.appstate.APP_ID"
android:value="@string/app_id" />
对于访问GameHelper.CLIENT_SNAPSHOT的人，您需要
<meta-data android:name="com.google.android.gms.games.APP_ID"
android:value="@string/app_id" />
保存游戏快照是一项旨在取代appstate的新功能，但是这种错误条件在从一个迁移到另一个时很容易运行。与说明您应该查看错误日志的异常相反，实际上没有日志条目显示在抛出异常之前的任何错误。

你不应该使用BaseGameActivity作为内部类。您应该从库中引用它。 Follow this link and follow the steps 1-8 under "Setting up your game project"
编辑：
首先，在项目中引用 BaseGameUtils 库。
现在看看这段代码：
import com.google.example.games.basegameutils.BaseGameActivity;
public class Test extends BaseGameActivity { //contained in the library
// override unimplemented methods here.
}
这就是你真正需要的。
