从KSOAP错误的Android通话SOAP服务 [英] Call SOAP service from android with ksoap error
本文介绍了从KSOAP错误的Android通话SOAP服务的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我对谷歌App Engine上运行一个Web服务，我就从Android设备调用可用的服务。我一直遵循与合并有关KSoap2最教程code，但我仍然获得Android的一个例外。这是code：
私有静态字符串METHOD_NAME =的getData;
私人静态字符串SOAP_ACTION =http://example.com/getData;
私人静态字符串WSDL_URL =http://arduino-data-server.appspot.com/FunctionsService.wsdl;
私人静态字符串NAMESPACE =http://example.com/;SoapObject要求=新SoapObject空间（namespace，METHOD_NAME）;SoapSerializationEnvelope信封=新SoapSerializationEnvelope（
SoapEnvelope.VER12）;
envelope.setOutputSoapObject（请求）;HttpTransportSE androidHttpTransport =新HttpTransportSE（WSDL_URL）;
尝试{
androidHttpTransport.call（SOAP_ACTION，信封）;SoapObject结果=（SoapObject）envelope.getResponse（）;
如果（结果！= NULL）{
TextView的T =（TextView中）this.findViewById（R.id.text_view）; t.setText（SOAP响应：\\ n \\ n+ result.getProperty（0）的ToString（））;
}
}赶上（IOException异常五）{
// TODO自动生成catch块
e.printStackTrace（）;
}赶上（XmlPullParserException E）{
// TODO自动生成catch块
e.printStackTrace（）;
}
这就是错误日志：

解决方案
试试吧..
尝试使用下面的code你mainactivityactivity低于在的setContentView（）来避免networkOnmainThread例外。
如果（android.os.Build.VERSION.SDK_INT＆GT; 9）{
。StrictMode.ThreadPolicy政策=新StrictMode.ThreadPolicy.Builder（）permitAll（）建（）;
StrictMode.setThreadPolicy（政策）;
}
不过，在做内部使用的AsyncTask不阻塞主线程后台线程操作重将是巨大的！
和还提到此链接...
I have a webservice running on Google app engine, and i would to call a available service from an android device. I've follow and merge code of most tutorial about KSoap2, but i still obtain an exception on android. this is the code:
private static String METHOD_NAME = "getData";
private static String SOAP_ACTION = "http://example.com/getData";
private static String WSDL_URL = "http://arduino-data-server.appspot.com/FunctionsService.wsdl";
private static String NAMESPACE = "http://example.com/";
SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME);
SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(
SoapEnvelope.VER12);
envelope.setOutputSoapObject(request);
HttpTransportSE androidHttpTransport = new HttpTransportSE(WSDL_URL);
try {
androidHttpTransport.call(SOAP_ACTION, envelope);
SoapObject result = (SoapObject) envelope.getResponse();
if (result != null) {
TextView t = (TextView) this.findViewById(R.id.text_view);
t.setText("SOAP response:\n\n"+ result.getProperty(0).toString());
}
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (XmlPullParserException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
and that's the error log:

解决方案
Try it..
Try using the below code inside your mainactivityactivity below setContentView() to avoid networkOnmainThread exception..
if (android.os.Build.VERSION.SDK_INT > 9) {
StrictMode.ThreadPolicy policy = new StrictMode.ThreadPolicy.Builder().permitAll().build();
StrictMode.setThreadPolicy(policy);
}
But, doing heavy operation inside background thread using AsyncTask without blocking main thread would be great!
