Answer 1

As you have seen in your logcat 1576-1576/com.example.neshat.androidhive2 D/RegisterActivity﹕ Register Response: which is the result of Log.d(TAG, "Register Response: " + response.toString());, response is an empty string, so your app will get org.json.JSONException: End of input at character 0 of at the line JSONObject jObj = new JSONObject(response);.

You should check response is not null and not an empty string first.
