around this issue 1- You have to learn HTTP CONNECTION using any library i recommend Volley for you here the the link
2- You have to learn JsonObject and JsonArray here
code :
   RequestQueue queue = Volley.newRequestQueue(this);// this = context
    final String url = yourURL
    // prepare the Request
    JsonArrayRequest getRequest = new JsonArrayRequest(Request.Method.GET, url, null,
            new Response.Listener<JSONArray>()

                public void onResponse(JSONArray response) {
                    //Log.d(TAG, "Login Response: " + response.toString());
                    // displayToast(R.string.toast_email_success);
                    if (response != null) {
                        try {

                            JSONArray JA = response;
                            int [] id = new int[JA.length()];
                            String [] name = new String[JA.length()];
                            String [] premalink = new String[JA.length()];
                            String [] descreption = new String[JA.length()];
                            String [] price_html = new String[JA.length()];
                            String [] stock_status = new String[JA.length()];
                            int [] stock_quantity = new int[JA.length()];
                            String [] image_src = new String[JA.length()];

                            for (int i = 0; i < JA.length(); i++) {
                                JSONObject JO = (JSONObject) JA.get(i);
                                JSONArray JA_inside_image = new JSONArray(JO.getJSONArray("images"));
                                    JSONObject JO_inside = (JSONObject) JA_inside_image.get(0);

                                if(JO.get("id")!=null) {
                                    id[i] = JO.getInt("id");
                                if(JO.get("name")!=null) {
                                    name[i]="Not Available Name";
                                if(JO.get("permalink")!=null) {

                                    premalink[i]="Not Available Link";
                                if(JO.get("description")!=null) {

                                    descreption[i]="Not Available Descreption";

                                if(JO.get("price_html")!=null) {

                                    price_html[i]="Not Available Link";

                                if(JO.get("stock_status")!=null) {

                                    stock_status[i]="Not Available Status";

                                if(JO.get("stock_quantity")!=null) {



                        } catch (JSONException e)




                    else {

                        Toast.makeText(getApplicationContext(), "Sorry Somesthing 

Wrong Happend try again later", Toast.LENGTH_LONG).show();
                new Response.ErrorListener()
                    public void onErrorResponse(VolleyError error) {

//                        Log.d("Error.Response", error.getLocalizedMessage());

Porting REST API connection code to Android NDK in c++

By : user2497437

hope this fix your issue I'm doing the EXACT same thing, and trust me: if you have no previous C++ experience, this might be a bit too costly for little benefit.
In my case, after some profiling, I reordered things around and had an initial jump in performance only by dropping DOM and using SAX. All the rest is only making things marginally better, like processing the response while packets are still being transmitted (i.e. not wait for the full response to start processing), and multiplexing requests on the same thread instead of starting a new thread for each.

Remove an application connection from SUP server when the application uninstalls from an android Device

I hope this helps . No, you can't.
When you uninstall an application, its process is killed (if it was running) and the application folder is deleted. Why does the connection has to be removed ?

Best way to model Android REST connection

By : Richard

Does that help You are describing tools that already exist. My favorite happens to be Retrofit but there are others out there. Retrofit can handle the success and fail responses and even map JSON directly to a POJO.
My API client
code :
public class ApiClient {

private static ApiInterface sApiInterface;

public static ApiInterface getApiClient(Context context) {

    //build the rest adapter
    if (sApiInterface == null) {
        final RestAdapter restAdapter = new RestAdapter.Builder()
        sApiInterface = restAdapter.create(ApiInterface.class);
    return sApiInterface;

public interface ApiInterface {

    void getProgram(@Path("id") int id, RetrofitCallback<Program> callback);

public class RetrofitCallback<S> implements Callback<S> {
private static final String TAG = RetrofitCallback.class.getSimpleName();

public void success(S s, Response response) {


public void failure(RetrofitError error) {
    Log.e(TAG, "Failed to make http request for: " + error.getUrl());
    Response errorResponse = error.getResponse();
    if (errorResponse != null) {
        Log.e(TAG, errorResponse.getReason());
        if (errorResponse.getStatus() == 500) {
            Log.e(TAG, "Handle Server Errors Here");
public class Program {
private doublea.models.Airtime Airtime;
private String id;
private String title;
private String shortName;
private String fullDescription;
private String shortDescription;
private doublea.models.Image Image;
private String imageName;
private List<Host> hosts = new ArrayList<Host>();
private List<Category> categories = new ArrayList<Category>();
private List<Airtime> airtimes = new ArrayList<Airtime>();

/** Getters and Setters */

public Program() {
private void executeProgramApiCall(int programId) {
    ApiClient.getApiClient(this).getProgram(programId, new RetrofitCallback<Program>() {

        public void success(Program program, Response response) {
            super.success(program, response);

may help you . Ankur, I had the same problem but replacing localhost with worked for me. Also make sure you have added the line
