Thanx in Advance, Goutham

Inside your 2nd activity( i.e the page which u load after the login) create

private class LoginTask extends AsyncTask<String, Void, Boolean> {

@Override
    protected void onPreExecute() {
        super.onPreExecute();
        // show a progress dialog indicating that its loading
    }

    @Override
    protected Boolean doInBackground(String... params) {
            // give your code that has to be loaded.
    }

    @Override
    protected void onPostExecute(Boolean success) {
        super.onPostExecute(success);
        //dismiss your progress dialog
    }
}

And call this LoginTask in your onCreate function of your 2nd activity as:

new LoginTask().execute();

Hope this may solve your issue...

simply show a progress dialog
