Any sample android code of Twitter Cards...? It is difficult to me

[changyoonjai]

I did not have experience to HTTP for android. So I use twitter4j.

==================== only twitter4j ================

I did finish simple works (OAuth, updateStatus …).

Now, I need to link to my app using Twitter Cards.

But I do not know what method I should call, like updateStatus(String status).

=============================================

I need sample code of Twitter Cards. It is difficult to me
