Android Posting to Facebook & Twitter via the URL Method


Hi Guys,

I've recently implemented some post sharing on various social media for in-game rewards to help my app get exposure when released and I'm having some issues with opening the Facebook app.

Example url

This is what I'm trying to achieve.
I would like the URL to open the Facebook app as priority and if the user does not have the app installed then it opens the internet browser.

I have this working fine for Twitter and Google Plus but Facebook always defaults to the browser instead of opening the Facebook app.

Any ideas?
