Unable to compile afservice

[fadookie]

These sample projects are using an ancient version of Gradle and AGP. To get them to build locally using my Oracle jdk-17.0.5 I had to upgrade Gradle to 7.3.3 and AGP to com.android.tools.build:gradle:7.2.0. I am then able to build Application target from Android studio, but when I try to build afservice I get the following errors which all say Not sure how to convert a Cursor to this method's return type (absolute paths have been redacted):
