[英]There is limitation in the use of Windows Azure Mobile with Android service that start at boot?
我編寫了一個與Windows Azure移動服務進行通信的Android應用程序,該應用程序通常在設備和android Azure數據庫之間發送數據,但是當我插入相同的代碼時,啟動時自動啟動的服務無法運行。 我在啟動時啟動的Android服務沒有問題。 Windows Azure Services Android服務沒有問題。
但是,當兩者(服務在啟動時啟動Android + Windows Azure Services)都無法運行時。
我需要幫助!

錯誤Exception.toString = com.microsoft.windowsazure.mobileservices.MobileServiceException:處理請求時出錯。 Exception.getCause = java.net.UnknownHostException:bn7.azure-mobile.net Exception.getStackTrace = [Ljava.lang.StackTraceElement; @ 40519770
正如錯誤描述已經說明的那樣,您在解決移動服務URL而不是移動服務本身時遇到了問題。
我的建議是,您的Android設備在啟動完成事件中沒有建立的Internet連接。 實例化MobileServiceClient
之前,請嘗試檢查Internet連接, 這是相應的代碼。 如果這是問題,請嘗試延遲實例化或等待直到服務中的連接。
