I just wanted to point out that the setup (https://github.com/LordZoltan/PagerSlidingTabStrip.Net/wiki/Using-and-customising-PagerSlidingTabStrip.Net) shows the xml as having
app:should_expand="true"
when really it should be
app:shouldExpand="true"
It shows the correct value below, but I didn't see that until later. :)
