It's pointing me to this code

public static boolean isAuthenticated(SharedPreferences prefs) {

    String token = prefs.getString(OAuth.OAUTH_TOKEN, "");
    String secret = prefs.getString(OAuth.OAUTH_TOKEN_SECRET, "");

    AccessToken a = new AccessToken(token, secret);

    Twitter twitter = new TwitterFactory().getInstance();
    twitter.setOAuthConsumer(Constants.CONSUMER_KEY,
            Constants.CONSUMER_SECRET);
    twitter.setOAuthAccessToken(a);

    try {
        twitter.getAccountSettings();
        return true;
    } catch (TwitterException e) {
        return false;
    }
}

specifically the line

AccessToken a = new AccessToken(token, secret);

It was all working fine when I used the twitter4j 2.1.1 but I had to update for other reasons

Answer 1

Instead of taking OAuth.OAUTH_TOKEN and OAuth.OAUTH_TOKEN_SECRET from prefs, go to your application page in Twitter and create your access token which you can do with a button on the bottom of the Details tab and it will give you the parameters you need.

Use those instead of token and secret strings in your code.

I do not know if this is the healthiest way to solve this problem since we are hard coding these values, but it solved my problem for the time being.

Answer 2

Change

twitter.getAccountSettings();

to

twitter.verifyCredentials();

Worked for me..

[Edit]

Also capture the exception when creating the AccessToken with empty token and secret.
