all: native app

# Provision the pinned toolchain (JDK, Go, Android SDK+NDK, Gradle) into
# $HOME/toolchains. One-time; then `. $HOME/toolchains/env.sh` before building.
setup:
	sh ci/setup-toolchain.sh

# Native executables, shipped inside the APK as lib*.so.
native: rsync rsh

# Real rsync, cross-compiled from pinned source via the Android NDK.
rsync:

# Go SSH transport, cross-compiled to Bionic PIE via the NDK (needs the NDK,
# like rsync). rsh logic is verified host-side by `make test`.

# Android app. Consumes the native libs from app/src/main/jniLibs. Uses the
# pinned system gradle; run from the repo root where settings.gradle lives. No
# wrapper jar is committed; gradle/wrapper/gradle-wrapper.properties only pins
# the version for F-Droid's gradlew, which refuses to build without it.
