Does this allow installing downloaded APKS files? If so, how do I get that to work -- I can't seem to figure it out.

(I do understand that it allows sharing of already installed apps that are generated from AAB files.)

The current approach does it without root.
How do you do it using root?
Can you please update the code of the sample to have both ways possible?

It'd be so cool to have this app on f-droid. The process isn't overly complicated, but you need to put metadata in a fastlane structure. Thanks so far!

When updating apps through this, it resets the apps data, except if it's not a split apk.
