This steps works fine for android 9

Would it be possible if you posted a detailed step by step of how did you made it work? did you have to build any apk from source? I would like to try it on Android 10 (LineageOS 17.1)

this app doesn't have to be in priv-app or platform signature so allowing this perms isn't needed at all

[sirtoobii]

@erfanoabdi can you please elaborate this a bit more. To my understanding, it has to be in priv-app, otherwise the app is unable to register it self as a system-wide location provider..

[erfanoabdi]

yeah, just placed it on /system/app/ and everything works fine (all checks passed) (had to add package name to config_locationProviderPackageNames as well)
