Android apks might not contain the game

This is just a FYI ticket, feel free to close if you don't see this in scope for this project.

Usecase: Using this tool to create a backup of ones whole Humble Library

Unfortunately, some Android apks downloaded from Humble only contain a downloader (see F-Droid's explanation of this feature) and not the whole game. I neither know how to detect this (without either launching the apk or by dissecting the apk with something like apktool) nor how to fetch the obb files automatically...

Games which do this:

• Grim Fandango Remastered (was at least in "Humble Mobile Bundle - Great Adventures" and "Humble Mobile Bundle 17")

(might add to this issue if I find more)

This is pretty common as an apk normally should not be larger than 2GB(An apk is a zip archive which has a hard limit to 2(4?)GB). If it is, then it should be split up into obb files, but installing obb is not possible when you sideload, so having the downloader handle it for you makes this possible.
