我一直试图通过Android从Axis2 Web服务请求数据时阻止KSOAP2调用超时,但一直未能这样做。如何在Android中防止可怕的KSOAP2连接超时

Web服务的背景。

我的Web服务正在Apache Tomcat服务器上运行,用于为站点返回实时信息。当我尝试通过浏览器时,它按预期工作,并在网站上也按预期工作。

的问题

然而,当我试图用同样的方法在我的Android应用程序,有时我会得到下面的堆栈跟踪误差。其他时候请求会成功。有时候,请求会立即超时,而其他时间会在超时前等待一分钟左右。

设备

我走过了三星Galaxy SII(平台2.3.3),并使用WiFi和3G使用具有相同结果的三星Galaxy SI(平台2.2.2)试了一下。但是,通过仿真器(Platform 2.2)使用它时,它永远不会超时。

我的代码

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(); 
    }

我已经更新KSOAP2从2.4到2.5.7,并试图设置超时限制,但我一直不成功如此远。所以要得到我的问题:

有其他人有这个问题,如果是的话,他们如何解决它?

不得不尝试超时用'TIMEOUT = 20000;'在'新HttpTransportSE(URL,60000); ' – Herry 2012-04-13 12:24:53

当超时启动时它会抛出SocketTimeoutException。

你应该抓住它在你的try-catch并处理超时,只要你喜欢

请注意,您不捕捉SocketTimeoutException – user2261183 2013-04-28 11:21:19
