Twitter.Authorize Won't Show Me Nothing

I'm developing a program using App Inventor that will tweet stuff.

I've assigned a button(btLogin) to authenticate with开发者_如何学运维 Twitter, using TwitterAPI.Authorize() and another button to check when it is authorized. If it throws me the even IsAuthorized it will display a label saying that. The problem is that when I click on the login button, nothing happens and when I click on the check button nothing happens too. What should I do?

Make sure you're following the full OAuthentication process. An example flow of the process can be seen here.
