Android Question Download assets via OKHttp2 or similar to reduce APK size

unzip it to the assets folder

You can not write to Assets folder. It is readonly. You need to extract them on another Path.

OK so I it would be acceptable for me to put the files in File.DirInternal so the next time the user loads the app, the files are still there. Only if they uninstall will they lose the assets.

In addition to studying

I will look at

to try to achieve this.

I don't know your app so my comment could be wrong, but from a user perspective the huge space occupied by your app stays the same whether you attach those 2000 files to the apk itself or you download them on a second time.
Why not park them on a server and download just what's needed or what the user selects?

On its start the app could download from a server an updated list of files (e.g. songs' titles) and show it to the user. Then the user highlights what he/she would like to download and your app uses FTP or Download itself to copy from server to device what is asked. You can easily keep track of what was already downloaded so next time your "complete" list could highlight those files already on the device (not needing a new download).

ps: I know that nowadays 50MB is not considered a huge amount of space but I'm old enough to still consider bit coding in order to save a few bytes..

pps: take in consideration that a single download operation (the zip file) could be less demanding on the server than hundreds of small downloads. And the number of expected users and the possibility they download at the same time is to be considered too. I guess that your final decision should depend on the very nature of your project.
