AccessToken accessToken = null;
ConfigurationBuilder builder = new ConfigurationBuilder();
					
builder.setOAuthConsumerKey(getConsumerKey(appName));
builder.setOAuthConsumerSecret(getConsumerSecret(appName));
					
Configuration config = builder.build();
OAuthAuthorization oauth = new OAuthAuthorization(config);
accessToken = oauth.getOAuthAccessToken(uid,d_password);

 public AccessToken getOAuthAccessToken(String screenName, String password) throws TwitterException {
        try {
            String url = conf.getOAuthAccessTokenURL();
            if (0 == url.indexOf("http://")) {
                // SSL is required
                // @see https://dev.twitter.com/docs/oauth/xauth
                url = "https://" + url.substring(7);
            }
            oauthToken = new AccessToken(http.post(url, new HttpParameter[]{
                    new HttpParameter("x_auth_username", screenName),
                    new HttpParameter("x_auth_password", password),
                    new HttpParameter("x_auth_mode", "client_auth")
            }, this));
            return (AccessToken) oauthToken;
        } catch (TwitterException te) {
            throw new TwitterException("The screen name / password combination seems to be invalid.", te, te.getStatusCode());
        }
