Android Question App mock or fake location

[AlpVir]

Does anyone know of an app that allows you to manage "mock locations" (or fake locations) with Android 13 (and later) and upload a GPX track, fooling other apps into thinking they're following that route and not the GPS satellite system?
I tried to develop one, but gave up due to the limitations of the new API and Google restrictions.
In fact, if anyone can give me some info, I might resume the project I abandoned.
Again: with the ability to upload a GPX track.
Thanks for your attention.

I can't help you if you need to do this in a real device. But if it's for development purposes you can use Android emulator for this. Works fine.
