android twitter retrieveRequestToken 401 on request token

Question

I am trying the following sample app for twitter oauth.

http://www.androidsdkforum.com/android-sdk-development/3-oauth-twitter.html

private void askOAuth() {
        try {
            consumer = new CommonsHttpOAuthConsumer(CONSUMER_KEY, CONSUMER_SECRET);
            provider = new DefaultOAuthProvider("http://twitter.com/oauth/request_token",
                                                "http://twitter.com/oauth/access_token",
                                                "http://twitter.com/oauth/authorize");
            String authUrl = provider.retrieveRequestToken(consumer, CALLBACK_URL);
            Toast.makeText(this, "Please authorize this app!", Toast.LENGTH_LONG).show();
            this.startActivity(new Intent(Intent.ACTION_VIEW, Uri.parse(authUrl)));
        } catch (Exception e) {
            Log.e(APP, e.getMessage());
            Toast.makeText(this, e.getMessage(), Toast.LENGTH_LONG).show();
        }
    }

When i run the following code it gives exception as following

"oauth.signpost.exception.OAuthNotAuthorizedException: Authorization failed (server replied with a 401). This can happen if the consumer key was not correct or the signatures did not match."

on this line String authUrl = provider.retrieveRequestToken(consumer, CALLBACK_URL);

I provided the correct 'key' and 'secret' does twitter giving me wrong key and secret ?
