java.lang.IllegalStateException: Fragment already added

Hi,

I got this error when I tapped the 5th tab as soon as the UI rendered:

Hi, @siddharth96

That you can not understand that you are using how this library from the error log,
Can you show me all of the parts of the code that sets up the FragmentManager?

[siddharth96]

Hi,

I don't think it's something wrong with your library. I'd overrident the getItem() implementation while extending PagerAdapter, and my implementation was causing this. Fixed my code, and this issue also went away.
I'll close this issue.

Thanks for this awesome library.
Cheers!
