# Builds the Android app with its core into dist\Firefox-VPN-<version>-android\:
# one APK per ABI (arm64-v8a, armeabi-v7a, x86_64). It first binds the Go
# core into app\android\app\libs\core.aar with gomobile, then builds the
# Flutter app. The version is "major.minor.patch" from app\pubspec.yaml, passed
# to the app (APP_VERSION) and to the core (version.Current).
#
# Needs Go, Flutter, the Android SDK with the NDK named in
# app\android\app\build.gradle.kts, a JDK (JAVA_HOME, else Android
# Studio's), and gomobile and gobind at the x/mobile commit given in
# core\doc\DEVELOPMENT.md.
