錯誤使用kso​​ap2

Question

我想我的應用程序連接到我的ASP創建，目前在localhost運行的Web服務的Android應用程序連接到ASP .NET Web服務。該應用程序試圖訪問採用3個整數的Coordonate方法。

我所提供的代碼和logcat的。我不得不提到，我是網絡服務的新手。

任何幫助將不勝感激！乾杯!

代碼：

Answer 1

嘗試在以下符合你係統的IP地址替換本地主機。

private static final String URL = "http://localhost:49934/Service1.asmx"; 

這可能對你有幫助。

至於即使你是在模擬器同一系統上運行然後測試也都asp.net和Android有本地主機不同的IP在某些情況下也許10.0.2.2。

Answer 2

我以前也有過類似的問題。請看How to call a local .NET web service from an Android Application。

希望它有幫助
