應用程序需要谷歌遊戲安裝應用程序崩潰時播放

Question

你好我有試圖在Android應用程序中使用LeaderBoards。

____________________________EDIT________________________________________________

好了，現在我想請點擊此鏈接Guide

我創建測試新的項目。我有像Giude一樣的代碼。

如果希望登錄顯示爲Google遊戲下載彈出窗口...好吧，下載它。

但如果我再次打開應用程序應用程序崩潰。我不知道爲什麼。 （我在電話號碼模擬器中啓動應用程序）

您有什麼想法嗎？ [我有一個新的項目只有來自指南的代碼。 + basegameUtils]

我發現我的錯誤..

我是沒有這個

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

在 <application></application>

，這是一個問題。
