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
Carry OpenSSL into the APK 7ef496a nandi 19d ago12# libssl.so OpenSSL, because the platform's own is not ours to load: an
13# libcrypto.so app's linker namespace refuses /system/lib64/libssl.so, and
14# without one there is no TLS at all on the phone

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