2# Glue the two halves of the frq Android app into an APK.
3#
4# libvidya.so the C ABI on Rust/egui, cross-compiled by buck2, and the
5# NativeActivity's own library (it holds android-activity's
6# glue, so it owns the event loop)
7# libjoltapp.so vidya's android/jolt_main.c plus frq's Jolt boot image,
8# dlopened by the above

10# through onActivityResult and a NativeActivity has nowhere to
11# deliver that

13# Neither half is built here beyond that last link: the UI library comes from
14# vidya's `just ffi-android` and the boot image from build-jolt-boot.sh. Both
15# native pieces are vidya's — only the boot image is frq's.
