This looks like a project from an L3 who got promoted and immediately left the team afterwards.
While it goes in the graveyard, I don’t know of a single person who ever used this.
I can see the appeal for it in apps like F-Droid and Briar where you might want to share an app that may not be available because of an Internet outage (accidental or deliberate).
When I’m traveling internationally I’m limited to 256kbps unless I buy a local sim. Sending an app without cell needed could be useful. Especially if it’s a big app like the DJI app.
Outside of that… nah. Maybe if you’re in rural Africa where cell service is spotty at best. But even there things have improved dramatically.
Why wouldn’t you use a dedicated APK extraction app of your choice to extract the APK file, then send to another device using a file sharing method of your own choice, be it WLAN-direct or even Bluetooth, instead of using Google’s locked-in proprietary tool?
