Guys, i found a way to install it on the newer android devices.
step 1: install RAR and Install Adastra (Windows version)
Step 2: open RAR and find your Adastra, then, hold down on it, and choose "Execute here"
Step 3: install Joi play, and the Renpai plugin for Joi play, both can be found here: https://joiplay.net/ you dont have to click the link if you don't trust me, just find joiplay on google.
step 4: click "add game" > "choose" > "Download" > "Adastra-17-win" > "Adastra.py" what happens next is just asking you a few questions on how you want to edit the game, don't worry about it, you can put random stuff, it won't affect a thing. Then, you have the game in, if you have any troubles at all, reply to this comment, there is a 90% chance I'll respond.
Also, i used this strategy to get games like Grove on my android device, love how i learned this from others, knowledge is to be shared with other people!
Also, if you're wondering, the apps look like this:
