Question

I want to fetch details of particular objects inside my activity.How can I get it.

Answer 1

Check the following code which receives the JSON array from the server for the given URL (http://tech.queryhome.com/json-request/check-login ) and returns the value of the error (Let me know if looking something different) -

public Boolean check_login(String url)
{
    DefaultHttpClient httpClient = new DefaultHttpClient();
    HttpEntity httpEntity = null;
    HttpResponse httpResponse = null;
    String response = null;
    JSONObject jsonObject;
    Boolean mylogin=false;

    HttpGet httpGet = new HttpGet(url);

    try {
        httpResponse = httpClient.execute(httpGet);

        httpEntity = httpResponse.getEntity();
        response = EntityUtils.toString(httpEntity);
    }
    catch (UnsupportedEncodingException e) {
        e.printStackTrace();
    } catch (ClientProtocolException e) {
        e.printStackTrace();
    } catch (IOException e) {
        e.printStackTrace();
    }


    try {
        jsonObject = new JSONObject(response);
        mylogin = jsonObject.getBoolean("error");
    }
    catch (JSONException e) {
        e.printStackTrace();
    }

    return mylogin;
}
