есть проблема в pasrsing "картинки", в вашем коде, пытаются получить «изображения» из js, т. е. js.getString ("картинки"); но нет никакой строки изображений в «js», см. мой ответ. –

Вот ваша проблема

for(int k = 0; k < hostimage_arr.length(); k++) 
{ 
    //Add this line 
    JsonObject innerObj=hostimage_arr.getJsonObject(k); 
    String image = js.getString("images"); // change it to innerObj.getString("images"); 
    if (_jArrImg.length() ==0) { 
     det_img.add("https://s3-ap-southeast-1.amazonaws.com/nanoweb/hostguesthome/uploadedfile/hostImages/user_12707aaf22_original.jpg"); 

    } 


    if (j==0) { 
     det_img.add("https://s3-ap-southeast-1.amazonaws.com/nanoweb/hostguesthome/uploadedfile/hostImages/"+image); 
    }

Ваш второй jsonarray (getuserlistdata) находится в объекте данных. но вы пытаетесь получить от userinfo jsonarray. удалите петлю usserarr, она решит вашу проблему.

Userarr=jsonObj.getJSONObject("data").getJSONArray("userinfo"); 

       // looping through All Contacts

Снимите петлю

   for (int i = 0; i < Userarr.length(); i++) {

    JSONObject c = Userarr.getJSONObject(i); 

        String Fname=c.getString("firstname"); 
        Fname_arr.add(Fname); 
        Log.v("Fname",Fname); 

      //change this 

      JSONArray _jArrImg = jsonObj.getJSONObject("data").getJSONArray("getuserlistdata"); 

     for (int j = 0; j < _jArrImg.length(); j++) { 
          JSONObject js = _jArrImg.getJSONObject(j); 

          JSONArray hostimage_arr = c.getJSONArray("hostImage"); 
          for(int k = 0; k < hostimage_arr.length(); k++) 
          { 
        // you are try get image from js object create a new object 
           JSONObject hostimage = hostimage_arr.getJSONObject(k); 
           String image = hostimage.getString("images"); 

           if (_jArrImg.length() ==0) { 

            det_img.add("https://s3-ap-southeast-1.amazonaws.com/nanoweb/hostguesthome/uploadedfile/hostImages/user_12707aaf22_original.jpg"); 

           } 


           if (j==0) { 
            det_img.add("https://s3-ap-southeast-1.amazonaws.com/nanoweb/hostguesthome/uploadedfile/hostImages/"+image); 
           } 

          }

Изменить этот код с кодом:

Проблема: Вы пытаетесь получить "images" от js объекта.

JSONArray hostimage_arr = c.getJSONArray("hostImage"); 
     for (int k = 0; k < hostimage_arr.length(); k++) { 
      JSONObject jImage = _jArrImg.getJSONObject(j); // Add this line 
      String image = jImage.getString("images"); // Update this line 

      if (_jArrImg.length() == 0) { 

       det_img.add("https://s3-ap-southeast-1.amazonaws.com/nanoweb/hostguesthome/uploadedfile/hostImages/user_12707aaf22_original.jpg"); 

      } 

      if (j == 0) { 
       det_img.add("https://s3-ap-southeast-1.amazonaws.com/nanoweb/hostguesthome/uploadedfile/hostImages/" 
         + image); 
      } 
     }

Вам нужно сделать другой jsonobject для получения различного массива из вашего ответа.

JSONObject jsonObjgetuserlistdata = response.getjObj(); 
JSONObject jobj , iobjimage; 

JSONArray jsonQueryArray = new JSONArray(jsonObjQuery .getString("getuserlistdata")); 
JSONArray jsonTeacherArray = new JSONArray(jsonObjTeacher .getString("teacher")); 

    for (int i = 0; i < jsonObjgetuserlistdata .length(); i++) { 
      jobj = jsonObjgetuserlistdata .getJSONObject(i); 
      JSONArray jsonImageArray = new JSONArray(jobj .getString("hostImage")); 

         for (int j = 0; j < jsonImageArray .length(); j++) { 
           iobjimage= jsonQuestionArray.getJSONObject(j); 
           image = iobjimage.getString("images" 
          } 
    }

Используйте библиотеку Gson для этого. Проверьте, пожалуйста, следующую ссылку: https://github.com/google/gson

Для этого вам просто нужно создать java pojo для вашего ответа.

и вызовите следующий метод:.

новый Gson() fromJson (UserString, YourResponsePojo.class) это вернет ваш объект ответа
