How to point my android app outside of Treehouse platform??? PLS HELP!!!

Hey guys, I'm in the middle of the course, and would like to eventually share what I've done in here with other people so I started this course without the Treehouse platform option as tought in this course thinking I would just figure that part out later, but now when I press "play", since the app in not linked to any HTTP address everything crashes. I don't want to buy or even have to manage website, is there any platform where can display my info for free and how can I link my app to where I am in this course (and please don't give me a terminal option it just doesn't work for me, I already tried everything on that side). Is there a way to simply link the app to Google Play (it doesn't needs to be in a commercial section or anything; I just want to put it somewhere out there)??? Thanks for helping out!
