How to get Json Response by hitting Url

public class MainActivity extends Activity {

String url = "http://api.androidhive.info/contacts/";

String jsonResponse = "";

@Override

protected void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

setContentView(R.layout.activity_main);

new Response().execute();

}

class Response extends AsyncTask<Void, Void, Void> {

@Override

protected Void doInBackground(Void... params) {

try {

DefaultHttpClient httpClient = new DefaultHttpClient();

HttpPost httpPost = new HttpPost(url);

HttpResponse httpresponse = httpClient.execute(httpPost);

HttpEntity entity = httpresponse.getEntity();

jsonResponse = EntityUtils.toString(entity);

} catch (ClientProtocolException e) {

// TODO Auto-generated catch block

e.printStackTrace();

} catch (IOException e) {

// TODO Auto-generated catch block

e.printStackTrace();

}

return null;

}

}

}

Note:

• Network operations should not be in userthread so that you have to use either async task or thread handler structure
• Internet permission should be mentioned in android manifest file
