我一直試圖通過Android從Axis2 Web服務請求數據時阻止KSOAP2調用超時,但一直未能這樣做。如何在Android中防止可怕的KSOAP2連接超時
Web服務的背景。
我的Web服務正在Apache Tomcat服務器上運行,用於爲站點返回實時信息。當我嘗試通過瀏覽器時,它按預期工作,並在網站上也按預期工作。
的問題
然而,當我試圖用同樣的方法在我的Android應用程序,有時我會得到下面的堆棧跟蹤誤差。其他時候請求會成功。有時候,請求會立即超時,而其他時間會在超時前等待一分鐘左右。
設備
我走過了三星Galaxy SII(平臺2.3.3),並使用WiFi和3G使用具有相同結果的三星Galaxy SI(平臺2.2.2)試了一下。但是,通過仿真器(Platform 2.2)使用它時,它永遠不會超時。
我的代碼
String NAMESPACE = "http://service.domain.ie";
String URL = "http://www.myhost.com/axis2/services/RealTime?wsdl";
String METHOD_NAME = "getStationData";
String SOAP_ACTION = "RealTime";
SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME);
request.addProperty("stationType", getStationType());
request.addProperty("stationApiCode", getApiCode());
SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);
envelope.dotNet = true;
envelope.setOutputSoapObject(request);
HttpTransportSE androidHttpTransport;
SoapObject response = null;
try {
androidHttpTransport = new HttpTransportSE(URL,60000); // Tried Setting the Timeout to 1 Minute
androidHttpTransport.debug = true;
androidHttpTransport.call(SOAP_ACTION,envelope);
response = (SoapObject)envelope.bodyIn;
} catch (IOException e) {
e.printStackTrace();
} catch (XmlPullParserException e) {
e.printStackTrace();
}

我已經更新KSOAP2從2.4到2.5.7,並試圖設置超時限制,但我一直不成功如此遠。所以要得到我的問題:
有其他人有這個問題,如果是的話,他們如何解決它?
不得不嘗試超時用'TIMEOUT = 20000;'在'新HttpTransportSE(URL,60000); ' – Herry 2012-04-13 12:24:53
