create facebook event in an android app

I am new to android, I want only to create a Facebook event from the app that I am going to develop. Later I will be adding the feature to invite friends. I would like to display the invitation as a notification or in any good way.

I did so much research on internet but could not find the solution.

I will really appreciate any solutions...

Thank you!
