Use this code in your asynchronous class
and you will get the response

try
{
     response = httpclient.execute(httpget);
     Log.e("Response", "Status:[" + response.getStatusLine().toString() + "]");
     Log.e("check",DataUrls.replyforum+DataUrls.strForumId+"?type=application/json");
     HttpEntity entity = response.getEntity();

     if (entity != null) 
     {                                              
        InputStream instream = entity.getContent();
        strResponseReply = RestClient.convertStreamToString(instream);
        Log.i("Result", "Result of converstion: [" + strResponseReply + "]");
        instream.close();
        return result;
     }
 } 
catch (ClientProtocolException e) 
{
     Log.e("REST", "There was a protocol based error", e);
}
catch (IOException e) 
{
     Log.e("REST", "There was an IO Stream related error", e);
}              
}
