我寫在裏面我是用谷歌地圖API的Android V2與mapviewballoons庫沿着一個應用程序，所以我有我使用兩個庫在我的Android項目：錯誤充氣類com.readystatesoftware.maps.TapControlledMapView
> android mapviewballoons
> google-play-services_lib
我獲得SHA1指紋又創造了一個Android應用程序圖例，重點for Android應用程序（帶證書）
但每當我跑我的應用程序，我得到不幸的是應用程序已經停止

您實際上不需要'com.readystatesoftware.maps'庫了，如果您正在使用** Map V2 ** – 2013-04-24 11:06:37
是的，我正在使用Map V2，那麼應該用什麼來代替com.readystatesoftware .maps.TapControlledMapView @ Archie.bpgc – 2013-04-24 11:09:01
@ChulbulPandey該庫將在單擊標記時顯示信息窗口。您可以輕鬆地使用[此處]的回電（https://developers.google.com/maps/documentation/android/reference/com/google/android/gms/maps/GoogleMap）。通過[文檔]（https://developers.google.com/maps/documentation/android/）也很重要 – 2013-04-24 11:20:42
