I’ve got LineageOS 18.1 running on my phone, together with microG and fdroid + FDroidPrivilegedExtension.
Before building I applied this patch with
patch -p1 -i /home/username/Documents/projects/FP4-lineageos/microgpatches/android_frameworks_base-R.patch
as described here.
Then I included these packages by adding
<project path="vendor/partner_gms" name="lineageos4microg/android_vendor_partner_gms" remote="github" revision="master" />
to my roomservice.xml file.
I also added two environment variables:
export WITH_GMS=true
export CUSTOM_PACKAGES="GmsCore GsfProxy FakeStore MozillaNlpBackend NominatimNlpBackend com.google.android.maps FDroid FDroidPrivilegedExtension"
Although I’m not sure if the latter is necessary for the build.
MicroG’s self-check reports that everything is fine.
The phone warns me about using test keys (duh).
The only thing that’s different is that the camera looks worse than before - 12MP instead of 48MP and no access to the wide-angle camera. I’m thinking about bundling their camera app as a system app and seeing if it works.
