So, it's been a while since I posted this and have been deep inside of the android development environment provided by GMS2. I bought the export module almost two months ago and am about to release a game with a bunch of features people say are messed up or out of date. I can confirm, yes they are out of date, but they are not unusable. I got admob to work perfectly, display regular and test ads, a couple weird bugs but I figured it out. There is very little documentation on it so I was mostly going in blind which is why people have such a hard time with it. As well, I could not do more advanced advertising strategies for example like the video with a reward system. I was however able to run full screen interstitials and banners. GMS2 simply doesn't have the extension updated to allow the use of ads with rewards.
Facebook had some issues at first but I eventually at least got it installed but not working, I had taken a break from it and haven't gone back, but so far so good. Also next to no documentation. The google extension works great as well. I got achievements working, I got leaderboards and logging in working, plenty of really cool interactivity. There is however again, almost no documentation. I had to resort to older forum posts and articles with out of date but similar examples and references but I found my way. The documentation exists, but its got a lot of missing info in it. I have since been able to set up a google account and loaded my game to the beta channel which means I have been able to build an APK. It wasn't easy to track down, but I was able to find it deep inside a folder for my game in the temp directory. I'm hoping the location can be moved in the future for where the apk is loaded to since it couldn't have been in a more confusing area and nobody on the internet knew it was there.
Hopefully this info can help either the hijacker or the staff on something, I'm looking forward to the future android updates as the GMS2 system isn't difficult to use once you know how to use it. In fact I wrote an object which I plan on importing to all of my future games which takes care of setting up ads and achievements as well as leaderboards, all automatically so I don't need to think about it so much anymore. Just know that there is a way and GMS2 is in fact worth it.
