我已經一派，但我並沒有得到任何有用的解決方案。我嘗試增加連接超時但沒有運氣。

真的不知道是什麼原因造成的問題，因爲企業的無線網絡工作正常，但本網站：maps.googleapis.com。

Answer 1

因爲我工作behiend代理我做這個步驟之後，我還沒有得到這個錯誤：

1. 要知道至極代理我背後我用這篇文章https://superuser.com/questions/346372/how-do-i-know-what-proxy-server-im-using

2. 在我去無線&網絡設置仿真器「 - >‘移動網絡’ - >」接入點名稱，我設置了端口的代理名稱，我在WPAD.DAT文件

3. 發現上運行配置> Android應用程序lication> App> Target>其他仿真器命令行選項：-http-proxy http：//：

我希望它能幫助別人！
