I’m looking for install FM Radio app (com.android.fmradio) on another Android distros, most of all on MIUI, but I don’t find an APK out.
It’s an original AOSP package and also is on LineageOS and eOS. But not on Google Play nor F-Droid.
You can get sources here : https://gitlab.e.foundation/e/os/android_packages_apps_FMRadio
Also, someone who has a FM-enabled device could extract the APK from system apps
I own one such device, but ROM is only Pie not Q or R.
You can also download a Q ROM image for a FM-enabled device, and unpack it to get the APK.
