Twitter integration with bb
 

Hi,

i m using following code to integrate twitter in my bb app. This code verify credentials but doesnt redirect to login page. To do so, i tried using this after verify credentials but still it doesnt open twitter login screen:-
user=m.getUserAccount();
m.follow(user);


package com.frt.util;

import java.io.IOException;

import net.rim.device.api.ui.component.Dialog;

import com.twitterapime.rest.Credential;
import com.twitterapime.rest.TweetER;
import com.twitterapime.rest.UserAccount;
import com.twitterapime.rest.UserAccountManager;
import com.twitterapime.search.LimitExceededException;
import com.twitterapime.search.Tweet;
import com.twitterapime.xauth.Token;


public class TwitterIntegration {

private static UserAccount user;

public static void integrate() {


Token token = new Token(TOKEN_ACCESS, TOKEN_SECRET);

Credential c = new Credential(USER_NAME, CONSUMER_KEY, CONSUMER_SECRET,token);

UserAccountManager m = UserAccountManager.getInstance(c);

try {

if(m.verifyCredential()){
Dialog.alert("You are now logged in");

Tweet t = new Tweet("Hi!!! This is my first tweet via Twitter API ME.");
TweetER ter = TweetER.getInstance(m);
t = ter.post(t);
}
else
Dialog.alert("User name and/or password are invalid!");
} catch (IOException e) {
// TODO Auto-generated catch block
Dialog.alert(e.getMessage());
} catch (LimitExceededException e) {
// TODO Auto-generated catch block
Dialog.alert(e.getMessage());
}
}
}

any one hv any idea how it will open twitter login screen?
