我正在開發一個Android應用程序，該應用程序使用Google地圖作爲android v2。我遇到的問題是，當我在Eclipse中使用AVD運行它時，我在log cat輸出中沒有收到認證錯誤。Android GoogleMaps API v2 auth錯誤，我在AVD上運行時沒有得到錯誤，但是在我的nexus上7我收到一個auth錯誤
我現在在Android平板電腦測試我的應用程序（的Nexus 7 2013年），我收到執行應用程序時，這個錯誤：
12-12 01:09:13.968: E/Google Maps Android API(14759): Authorization failure. Please see https://developers.google.com/maps/documentation/android/start for how to correctly set up the map.
12-12 01:09:13.968: E/Google Maps Android API(14759): Ensure that the following correspond to what is in the API Console: Package Name: dcs.aber.ac.uk.cs211.group02, API Key: AIzaSyDcnzt6cdjEbCXSCRSTezmUHbaPW679if8, Certificate Fingerprint: 52FDB9ABBBAA062226834E35BF6A39FA2A3E27A7
我試圖回藍的API密鑰，一個在logcat的與google API控制檯中提供的相匹配。
我已經嘗試了幾次乾淨的項目/乾淨安裝在設備上，仍然沒有運氣。應用程序的工作正常，只有地圖沒有。
這裏是我的manifest.xml所有權限似乎沒問題。
