Doesn't request background location permission in Android 10

[eplinux]

In Android 10, a new location permission was introduced. Therefore, apps have to request android.permission.ACCESS_BACKGROUND_LOCATION in order to access location when running in background. Manually allowing the backend to access background location via local terminal doesn't seem to work.

A workaround is proposed by adding this permission to the AndroidManifest.xml:

microg/GmsCore#986

How did you install Ichnaea ?

I used one of those bundles : https://github.com/FriendlyNeighborhoodShane/MinMicroG_releases

I first installed it from Magisk and got the same error as you.

I then deinstalled the Magisk module, and installed MinMicroG via TWRP and voilà, problem solved ! :-)
