我已經開始創建一個使用Google Map Api V2的演示應用程序,我遵循Google指南http://developer.android.com/google/play-services/maps.html & http://www.truiton.com/2013/05/android-mapfragment-example/。Google Map API版本2無法聯繫Google服務器
地圖活動正在加載,但實際谷歌地圖沒有加載,並顯示錯誤消息:
10月6日至18日:19:23.717:I /谷歌地圖的Android API(29990):無法聯繫Google服務器。連接建立後將進行另一次嘗試。
06-18 10:19:38.903:E谷歌地圖Android API(29990):無法加載地圖。聯繫Google服務器時出錯。這可能是一個身份驗證問題(但可能是由於網絡錯誤)。
可能的錯誤是由於造成的事實,我對3G /邊緣比4G網絡或Wifi慢,又是可能導致連接超時???
下面是我的活動:
