3# build-android.sh — empaca un crate Llimphi-Android como APK firmado.
4#
5# Uso:
6#   ./build-android.sh <crate-dir> [arch] [profile]
7#
8#   crate-dir : path al Cargo.toml del crate Android (cdylib + android_main)
9#   arch      : arm64 | x64           (default arm64)
10#   profile   : release | debug       (default release)
11#
12# Requisitos:
13#   - rustup target add aarch64-linux-android x86_64-linux-android
14#   - cargo install xbuild       (binario `x`)
15#   - cargo install cargo-ndk    (opcional, sólo si querés build sin APK)
16#   - NDK r27+ en $ANDROID_NDK_HOME
17#   - Android SDK en $ANDROID_HOME (cmdline-tools + build-tools)
18#   - PEM dev en $LLIMPHI_PEM (se crea automáticamente la primera vez)
19#
20# Resultado:
21#   target/x/<profile>/android/<crate>.apk   — APK firmado v2, instalable con
22#                                              `adb install -r <apk>`.
