Getting a Background Process Running / Adding a Side-loaded App to the Library

[Joshua Smith]

My application is written using WebXR and viewed using Firefox Reality on the Focus 3 headset. In order to allow offline use, I have a helper app with an embedded web server.

Starting with Android 10, it's not possible for an app to start an activity on boot. (BOOT_COMPLETED is a broadcast event, and broadcast events handlers are not allowed to start activities.)

Any ideas for a workaround for that?

Alternately, I could have the user manually start our process, but our process is not appearing in the Library of things we can run. It *does* appear in the list of things you can run in Kiosk Mode. What's the secret to getting a side-loaded app to appear in the Library?
