Fetch_User_Data.php Şöyledir hardcoding Testi

 User returnedUser=null; 
     try { 

      post.setEntity(new UrlEncodedFormEntity(dataToSend)); 

      HttpResponse httpResponse = client.execute(post); 

      HttpEntity entity = httpResponse.getEntity(); 

      String result = EntityUtils.toString(entity); 
//until here hardcoding fills correctly returnedUser 
      JSONObject jObject = new JSONObject(result); 
returnedUser = new User("hello", 42, user.username, user.password); 
// this is hardcoded string that let returnedUser ==null 
// so perhaps problem is in jObject    

if (jObject.length() != 0){ 
       Log.v("happened", "2"); 
       String name = jObject.getString("name"); 
       int age = jObject.getInt("age"); 

       // returnedUser = new User(name, age, user.username, user.password); 
      } 



     } catch (Exception e) { 
      e.printStackTrace(); 
     } 

     return returnedUser; 
    }

Çok üzgünüm. Sorun bir çift hafta boyunca beni delirtmiş olsa bile basitti! ... "Fetch_User_Data.php" dosyasını getirme bak ve sonra "FetchUserData.php" olarak arayıp yapılabilir olacakları dize bakmak
