I want to know how the APK installing in Android exactly works. E.g. a downloaded APK is installed when I press 'install' but there is some process, right? I want to know that.
Inside the APK of the game called Mini Militia I found there are three folders inside the assets folder: HD, HDR and SD. The APK installs one of those according to the phone's resolution maybe, I don't know. I edited some files in the HD folder but my phone installs the files from HDR. My mobile is a OnePlus One. I want to know if I could change that.
