I want to create apk files for the games I’ve purchased on Google Play. If I use the Google Files apps, it won’t compress the whole game into apk (for example, APK file size for ‘Bendy and the Ink Machine’ is only ~2mB.) For now, only local backup seems to be the functional method.
Use an alternative app store such as aurora -> https://auroraoss.com/
If you log in with your google credentials, it will show as paid, and allows you to download the installer from the context menu in the top right corner (click on.the three dots and go to “manual download”).
