I am creating an Android app that uses Twitter4J to read some user info.

This was all working fine, but this evening when I start the app and the user logs on to Twitter I get an exception:

    Twitter twitter = new TwitterFactory().getInstance(twitterID,twitterPassword);
    u = twitter.verifyCredentials();

This throws the following exception on the verifyCredentials() call:

As I mentioned, this has not changed for weeks, but has just suddenly stopped working.. I have also noticed that if I instantiate my Twitter object annonymously (dont pass username and password) then it still allows me to retrieve information/users/statuses from twitter (obviously verifyCredentials() does not work here though as it is an anonymous user)

Has anyone experienced this issue or similar?

Thanks in advance!

    The Twitter API no longer supports Basic Authentication, you must change your application to use OAuth, http://dev.twitter.com/pages/auth_overview , which is built into Twitter4J also.
