Problems with Json receiving inner value

Question

I have this code which in turn what it does is to fetch an id from the database but the first value it will fetch is 0 past 1 second it will fetch the correct value tested with a output text .

Example First id it will fetch: 0

After 1 second gets id: 33

I click again to get a close id or 34 it will fetch: 33

After 1 second I get id :34

I used a dialog to try to solve the problem but did not solve.

 JSONObject jsa = null;
    try {
        jsa = new JSONObject(myJSON);


        favId = jsa.getInt("FavoritoId");



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

        dialog.dismiss();
