Ошибка при вызове веб-сервисов

Question

Я начинаю как в андроидах, так и в веб-службах (на основе Java). Что я пытался сделать, так это запросить один из методов из веб-службы, который не требует каких-либо параметров для первоначального тестирования и поймать ответ в logcat или простое текстовое представление. Сначала он дал мне ошибку аутентификации, снабженный базовой аутентификации HTTP к веб-службам, как это требуется то же самое, а затем

, когда я запустил программу снова начал бросать исключение после этой строки, где я звонил:

httpTransport.call(SOAP_ACTION, envelope); 

Ошибка я получаю:

04-26 10: 10: 12,945: I/System.out (322): org.xmlpull.v1.XmlPullParserException: неожиданный тип (позиция: TEXT enter code here 04-26 10: 10: 12.945: I/System.out (322): ------ = _ Part_56. .. @ 5:13 в java.io.InputStreamReader@40580270)

Я много искал и даже искал почти все вопросы в стеке над потоком. но не нашел полезного решения, поэтому снова поднимал этот вопрос. пожалуйста, пройти через код и дайте мне знать, где я буду неправильно

Answer 1

Попробуйте этот код

try { 
       HttpTransportSE androidHttpTransport = new HttpTransportSE(URL); 

       androidHttpTransport.call(SOAP_ACTION, envelope); 

       SoapObject result = (SoapObject) envelope.bodyIn; 

       if (result != null) { 

       tvResult.setText(result.getProperty0).toString()); 

       } else { 

        tvResult.setText("No Output"); 
       } 

      } catch (Exception e) { 
       // TODO: handle exception 
       e.printStackTrace(); 
       tvResult.setText(e.toString()); 
      } 

надеюсь, что это поможет полностью.
