我是Android的新手，我創建了一個小應用程序並調用了Web方法。 它始終可以正常工作，但是突然停止工作，無法連接到WS。 我正在使用KSOAP2。 我能夠通過瀏覽器訪問WS。 我沒有對代碼進行任何更改。在交付時，它運行正常，一切正常。

版本-GingerBread，使用Eclipse，WS是asmx。 我正在使用2.6.5 jar的KOSAP2 ..請幫助我非常關鍵

代替

 Object result = (Object)envelope.getResponse();

嘗試使用

 SoapPrimitive result = (SoapPrimitive) envelope.getResponse();
