Caldroid with default PageViewer Fragments

[PietroAvolio]

Hi, I'd like to use a caldroid embedded fragment in my app, in the second tab of a viewpager that already contains a fragment in the first tab.

I'm getting a lot of errors and i don't know how to move to fix that but i really want to use this calendar.

Here there's a paste of my actual code:

This is the default code generated when you create a new activity in ecplise. I'm new to android so sorry if this is a dumb question.
