# Cross-compile the bundled Nym SOCKS5 sidecar (nym-socks5-client) for Android.
# scripts/android.sh copies the result into the APK's jniLibs as
# libnym_socks5_client.so so Goblin can launch the mixnet client on-device.
#
# Usage: NYM_SRC=../nym scripts/nym-android.sh [v7|v8|x86|all]
#   NYM_SRC  path to the Nym workspace checkout (default: ../nym)
# Requires: ANDROID_NDK_HOME, rustup android targets, cargo-ndk.
#
# Note: the sidecar is patched to use preconfigured webpki roots on Android
# (common/http-api-client/src/registry.rs) — the default rustls platform
# verifier needs the app's JNI context, which a standalone process lacks.
