  public class SenddataActivity extends Activity {

                if (resEntity != null) {    
                    String r = EntityUtils.toString(resEntity);
                    if(r.startsWith("success")) {
                    Toast.makeText(getApplicationContext(), "data sent", Toast.LENGTH_LONG).show();
                    }
