How to update UserTimeline once posted Tweet?

android

#1

At the moment I have the following in order to post a tweet.

    final Intent intent = new ComposerActivity.Builder(this)
            .session(session)
            .createIntent();
    startActivity(intent);

How do I do something once the tweet has been sent/completed?
Example, make a toast or update the timeline.

Any assistance would be great, thanks in advance.
