AsyncTask.doInBackground does not receive a call 2.3, working with 4.0+

Question

I have this AsyncTask:

public static void login(final String email, final String password,
            final String token, final SocketHandler handler) {
        execute(new AsyncTask<Void, Void, Void>() {

            @Override
            protected Void doInBackground(final Void... params) {
                Log.d("ACEPTAR", "DOINBACKGROUND");
                String url = handler.servidor.getUrl();
                url += "/login-usuario";
                String str;
                try {
                    str = postResponseFromServer(url, "mail", email, "pass",
                            password, "tipo", "1", "token", token);
                    Log.d("ACEPTAR", str);
                    final CustomJSONObject object = new CustomJSONObject(str);
                    final CustomJSONObject object2 = new CustomJSONObject();
                    object2.put("datos", object);
                    final CustomJSONArray array = new CustomJSONArray();
                    array.put(object2);
                    handler.on("resultado-login", array);
                } catch (final Exception ex) {
                    ex.printStackTrace();
                    handler.on("error-login", new CustomJSONArray());
                }
                return null;
            }
        });
    }

    @SuppressLint("InlinedApi")
    private static void execute(final AsyncTask<Void, Void, Void> task) {
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.HONEYCOMB) {
            task.executeOnExecutor(AsyncTask.SERIAL_EXECUTOR);
        } else {
            task.execute();
        }
    }

I try to do it on 3G, it always works. Then I connect to Wi-Fi. AsyncTask is called in 4.0+, but not in 2.3.7 -.

Did I miss something?

Try creating a separate thread and do your stuff there, post your results using Activity.runInUiThread (). See if there are problems with this. If there are no problems, this may be due to some AsyncTask errors.
