I develop an Android app for people to take pictures, and these pictures must be geolocalized.
If ony the camera app asks for GPS, then the GPS signal is lost every time the user exits the camera app. There are many closed-source apps to "keep" the signal (example: GPS Locker).
So, I would like my app to have such a "GPS fix signal keeper", but with these requirements:
- Running in the background, my own activities should not kick the fix out
- Open source (Apache 2.0 compatible), as I want to integrate it inside my app
- Preferably a library, but an app from which I could copy/paste is OK too
