安装的应用程序崩溃时应用程序需要 Google Games Play

Question

您好，我正在尝试在 Android 应用中使用排行榜。

____________________________编辑________________________________________________

好的，现在我尝试点击此链接Guide

我创建新项目进行测试。我有类似 Giude 的代码。

如果要登录显示弹出用于下载谷歌游戏...好的，下载它。

但是如果我再次打开应用，应用就会崩溃。我不知道为什么。 （我在手机号启动应用，模拟器）

你有什么想法吗？ [我有一个新项目，只有指南中的代码。 + basegameUtils]

public class MainActivity extends Activity implements
        GoogleApiClient.ConnectionCallbacks,
        GoogleApiClient.OnConnectionFailedListener, View.OnClickListener {

我发现我的错误..

我没有这个

<meta-data android:name="com.google.android.gms.games.APP_ID"
        android:value="@strings/app_id" />

在<application></application>
