private ProgressDialog pDialog;
@Override
protected void onPreExecute() {
super.onPreExecute();
uid = (TextView)findViewById(R.id.uid);
myurl = (TextView)findViewById(R.id.url);

pDialog = new ProgressDialog(MainActivity.this);
pDialog.setMessage("Getting Data ...");

}
@Override
protected JSONObject doInBackground(String... args) {
JSONParser jParser = new JSONParser();
// Getting JSON from URL
JSONObject json = jParser.getJSONFromUrl(url);
return json;

}
@Override
protected void onPostExecute(JSONObject json) {
pDialog.dismiss();
try {


JSONObject myobject = new JSONObject("h0");

int id = myobject.getInt("id");
String myurl= myobject.getString("url");

uid.setText(""+id);
myurl.setText(myurl);

} catch (JSONException e) {
e.printStackTrace();
}
}
}

You are not calling the correct jsonObject, have a look at your code...myObject is new json..so of course it will he empty. You should use json.getJsonObject(h4). I'm answering using mobile so sorry about typos and formatting
