Get JSON Data from URL Using Android?

Question

I am trying to get JSON data by parsing login url with username and password. I have tried by using below code but I can't get any responses. Please help me.

I am using HTTP Process and API level 23.

I need to parse my URL and get below Response

{     "response":{                 "Team":"A",                 "Name":"Sonu",                 "Class":"First",               },                 "Result":"Good", } 

Below My code :

public class LoginActivity extends Activity {      JSONParser jsonparser = new JSONParser();     TextView tv;     String ab;     JSONObject jobj = null;     @Override     protected void onCreate(Bundle savedInstanceState) {         super.onCreate(savedInstanceState);         setContentView(R.layout.login);          new retrievedata().execute();      }      class retrievedata extends AsyncTask<String, String, String>{          @Override         protected String doInBackground(String... arg0) {             // TODO Auto-generated method stub             jobj = jsonparser.makeHttpRequest("http://myurlhere.com");              // check your log for json response             Log.d("Login attempt", jobj.toString());              try {                 ab = jobj.getString("title");             } catch (JSONException e) {                 // TODO Auto-generated catch block                 e.printStackTrace();             }             return ab;         }         protected void onPostExecute(String ab){              tv.setText(ab);         }      }  }

Easy way to get JSON especially for Android SDK 23:

public class MainActivity extends AppCompatActivity {  Button btnHit; TextView txtJson; ProgressDialog pd;  @Override protected void onCreate(Bundle savedInstanceState) {     super.onCreate(savedInstanceState);     setContentView(R.layout.activity_main);      btnHit = (Button) findViewById(R.id.btnHit);     txtJson = (TextView) findViewById(R.id.tvJsonItem);      btnHit.setOnClickListener(new View.OnClickListener() {         @Override         public void onClick(View v) {             new JsonTask().execute("Url address here");         }     });   }   private class JsonTask extends AsyncTask<String, String, String> {      protected void onPreExecute() {         super.onPreExecute();          pd = new ProgressDialog(MainActivity.this);         pd.setMessage("Please wait");         pd.setCancelable(false);         pd.show();     }      protected String doInBackground(String... params) {           HttpURLConnection connection = null;         BufferedReader reader = null;          try {             URL url = new URL(params[0]);             connection = (HttpURLConnection) url.openConnection();             connection.connect();               InputStream stream = connection.getInputStream();              reader = new BufferedReader(new InputStreamReader(stream));              StringBuffer buffer = new StringBuffer();             String line = "";              while ((line = reader.readLine()) != null) {                 buffer.append(line+"\n");                 Log.d("Response: ", "> " + line);   //here u ll get whole response...... :-)               }              return buffer.toString();           } catch (MalformedURLException e) {             e.printStackTrace();         } catch (IOException e) {             e.printStackTrace();         } finally {             if (connection != null) {                 connection.disconnect();             }             try {                 if (reader != null) {                     reader.close();                 }             } catch (IOException e) {                 e.printStackTrace();             }         }         return null;     }      @Override     protected void onPostExecute(String result) {         super.onPostExecute(result);         if (pd.isShowing()){             pd.dismiss();         }         txtJson.setText(result);     } } }
