这是我的异步任务类：

envelope.setOutputSoapObject(request);

Log.d("SelfCare", "request= " + request);
androidHttpTransport = new HttpTransportSE(URL);
Log.d("SelfCare", "androidHttpTransport= "
+ androidHttpTransport);
androidHttpTransport.call(SOAP_ACTION, envelope);
SoapPrimitive response = (SoapPrimitive) envelope.getResponse();
Log.d("SelfCare", "response= " + response);
/*

*/
String jsonResponse = "";
jsonResponse = response.toString();
// A JSONTokener is needed in order to use JSONObject correctly
JSONTokener jsonTokener = new JSONTokener(jsonResponse);
// Pass a JSONTokener to the JSONObject constructor
JSONObject jsonObj = new JSONObject(jsonTokener);

defaultmsisdn = c.getString("defaultmsisdn");
Log.d("SelfCare", "message= " + message);
Log.d("SelfCare", "sessionid= " + sessionid);
}
/*

} else {
Toast.makeText(getBaseContext(), "Error", Toast.LENGTH_LONG)

} catch (Exception e) {

Toast.makeText(getApplicationContext(), e.getMessage(),
Toast.LENGTH_LONG).show();
e.printStackTrace();
}
return null;
}
@Override

// Log.i(TAG, "onPostExecute");
// tv.setText(fahren + "° F");
pDialog.dismiss();
if (message.equalsIgnoreCase("Login Successful.")) {
if (defaultmsisdn.equalsIgnoreCase("null") && saleid == 0) {
et_username.setText("");

这就是我得到异常的那一行::
androidHttpTransport.call(SOAP_ACTION, envelope);
注意：-我不经常收到异常，但是当我尝试登录我的应用程序和调试我的应用程序时的另一件事，然后在我的 catch 块中会出现此消息java.net.sockettimeoutexception
