Since there are 34 "Gain Priv" listed on that page for Android (many versions) in 2017, and well over 200 listed for 2016, I would imagine with those as a starting point it might not be too hard to look for likely candidates that have been weaponized (or have working proof of concept code) if you search around a bit. It's not exactly
easy, but given the huge number of exploits to work with, it would probably yield something without too much work.
I did notice that the entries there include whether there's a known metasploit module, which none that I looked at had one shown there. I googled metasploit and android and found some video tutorial for hacking a Android phone using metasploit from early 2017[1], so maybe that will help you. In any case, good luck if you try.
