Sorry if this question is obvious. But I wasn´t able to find an answer to my question. How do I manage to make an android apk that runs on a lot of devices. Currently I´m using ASTC textures. They work great on my device. For the store I have chosen multy format to support all other devices. But my app gets really big then. Do I need to make a build for each texture format?
Do you have a good guide for android packaging and distributing? I only find unity tutorials everywhere. 
I followed the mobie performance wikis here. But performance is not my issue here. The game runs smoothly with 60 fps.
