# UltrafastSecp256k1 -- Android Build Script
|
|
# ============================================================================
|
|
# Builds native libraries for all Android ABIs using the Android NDK.
|
|
#
|
|
# Prerequisites:
|
|
# - Android NDK installed (r25+ recommended)
|
|
# - Set ANDROID_NDK_HOME or ANDROID_NDK environment variable
|
|
# - CMake 3.18+ and Ninja
|
|
#
|
|
# Usage:
|
|
# ./build_android.sh # Build all ABIs (arm64, armv7, x86_64, x86)
|
|
# ./build_android.sh arm64-v8a # Build ARM64 only
|
|
# ./build_android.sh armeabi-v7a # Build ARMv7 only
|
|
# ./build_android.sh x86_64 # Build x86_64 (emulator)
|
|
# ANDROID_MIN_SDK=21 ./build_android.sh # Override minimum SDK
|
