body: <p>i m getting this response in a result of GET request to server</p>
  
  <pre><code>{"LL": { "control": "dev/sys/getkey", "value": "4545453030304138303046392035343733373432363020323031332D30322D31312031383A30313A3135", "Code": "200"}}
  </code></pre>
  
  <p>i just want to extract the value of <code>"value"</code> from the above json response.</p>
  
  <p>I m using this code to get this response</p>
  
  <pre><code>findViewById(R.id.button1).setOnClickListener(new OnClickListener() {
  
          @Override
          public void onClick(View v) {
  
              HttpResponse response = null;
              try {
                  HttpClient client = new DefaultHttpClient();
                  HttpGet request = new HttpGet();
                  request.setURI(new URI(
                          "http://192.168.14.247/jdev/sys/getkey"));
                  response = client.execute(request);
              } catch (URISyntaxException e) {
                  e.printStackTrace();
              } catch (ClientProtocolException e) {
                  // TODO Auto-generated catch block
                  e.printStackTrace();
              } catch (IOException e) {
                  // TODO Auto-generated catch block
                  e.printStackTrace();
              }
  
              String responseText = null;
              try {
                  responseText = EntityUtils.toString(response.getEntity());
              } catch (ParseException e) {
                  // TODO Auto-generated catch block
                  e.printStackTrace();
                  Log.i("Parse Exception", e + "");
  
              } catch (IOException e) {
                  // TODO Auto-generated catch block
                  e.printStackTrace();
                  Log.i("IO Exception 2", e + "");
  
              }
  
              Log.i("responseText", responseText);
  
              Toast.makeText(MainActivity.this, responseText + "",
                      Toast.LENGTH_SHORT).show();
  
          }
  
      });
  </code></pre>
  
  <p>my question is that how can i parse this and get the value of only <code>"value"</code> tag.
  thanks</p>
