Twitter4j Android FileNotFoundException by executing “getFollowersIDs” or “getDirectMessages”

Question

I use twitter4j on my Android 1.6 phone to request user related data such as all new direct messages or follower ids. It works fine if I only request trends or other user unrelated information (trends for example) but if I try to query information such as the follower ids or new direct messages twitter4j throws an TwitterException with the following cause

java.io.FileNotFoundException: http://api.twitter.com/1/direct_messages.json

I create an instance of twitter with the following code:

TwitterFactory twitterFax = new TwitterFactory();
twitterInstance = twitterFax.getInstance(USERNAME, USER_PASSWORD);

The exception throws here:

try {

     ResponseList<DirectMessage> directMessages = twitterInstance.getDirectMessages();

     if(directMessages.size() > 0){

        publishProgress(directMessages.toArray());
     }

} catch (TwitterException e) {
    // TODO Auto-generated catch block
    e.printStackTrace();
}

Why does it not work?

The twitter API doesn't support simple authentication anymore (you also didn't verify them as well), use OAuth:
