我使用KSoap從我的android程序訪問.net web服務。當web服務關閉或web服務url錯誤時，我的應用程序崩潰。KSOAP：Android應用程序崩潰時，web服務url是錯的
有人可以告訴我一種方法來處理這個問題。
我的代碼去如下
public String logOut(String prefURL){
String Desc = "logging out";
String NAMESPACE="http://tempuri.org/";
String METHOD_NAME = "Logout";
String SOAP_ACTION = "http://tempuri.org/Logout";
String URL = prefURL+"/Authentication.asmx";
//creating soap object
SoapObject Request = new SoapObject(NAMESPACE, METHOD_NAME);
//adding properties to Request Soap Object
Request.addProperty("resourceID", ResourceID);
Request.addProperty("organisationID", OrganisatoinID);
Request.addProperty("description", Desc);
Request.addProperty("sessionID", SessionID);
Request.addProperty("imei", LoginActivity.deviceid);
Request.addProperty("longtitude", String.valueOf(LoginActivity.RDMSLon));
Request.addProperty("langtitude", String.valueOf(LoginActivity.RDMSLat));
Request.addProperty("deviceType", 4);
//creating soap envelop
SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);
envelope.dotNet=true;
envelope.setOutputSoapObject(Request);
//creating transport object
AndroidHttpTransport androidHttpTransport = new AndroidHttpTransport(URL);
try {
androidHttpTransport.call(SOAP_ACTION, envelope);
SoapPrimitive resultString = (SoapPrimitive)envelope.getResponse();
//jason array stored into a string
jstringarray = String.valueOf(resultString);
Log.v(TAG, "Logout" + jstringarray);
jArray = new JSONArray(String.valueOf(jstringarray));
JSONObject json_data = null;
json_data = jArray.getJSONObject(0);
Status = json_data.getString("Status");
Log.v(TAG, "Logout: "+ Status);
} catch (IOException e) {
e.printStackTrace();
} catch (XmlPullParserException e) {
e.printStackTrace();
} catch (JSONException e) {
e.printStackTrace();
}
return Status;
}
logcat的提取物提前

感謝。
代碼中有很多地方可能會發生崩潰。附上日誌請 – Flavio
我也附上日誌。你現在可以幫忙嗎？謝謝。 –
