# Build OpenPay JNI library for all Android ABIs and stage into the
|
|
# Kotlin module's jniLibs directory.
|
|
#
|
|
# Output layout:
|
|
# kotlin/openpay/src/main/jniLibs/arm64-v8a/libop_ffi_jni.so
|
|
# kotlin/openpay/src/main/jniLibs/armeabi-v7a/libop_ffi_jni.so
|
|
# kotlin/openpay/src/main/jniLibs/x86/libop_ffi_jni.so
|
|
# kotlin/openpay/src/main/jniLibs/x86_64/libop_ffi_jni.so
|
|
#
|
|
# Prerequisites:
|
|
# - Android NDK r25 or later (set ANDROID_NDK_HOME or
|
|
# ANDROID_NDK_ROOT, or pass --android-platform to cargo-ndk).
|
|
# - rustup target add aarch64-linux-android armv7-linux-androideabi \
|
|
# x86_64-linux-android i686-linux-android
|
|
# - cargo install cargo-ndk
|
|
#
|
|
# Usage:
|
|
# bash scripts/build-android.sh [--release|--debug] [--min-sdk N]
|
|
#
|
|
# The four ABIs map to the Android ABI conventions per Android Developer
|
|
# documentation (developer.android.com/ndk/guides/abis):
|
|
# arm64-v8a — modern 64-bit ARM (all current Android devices)
|
|
# armeabi-v7a — older 32-bit ARM (pre-2019 devices)
|
|
# x86_64 — emulator on Intel/AMD Macs and Linux dev hosts
|
|
# x86 — older 32-bit emulator (rarely used; included for completeness)
