build-termux.sh

#!/usr/bin/env bash
# StreamClip Build Script for Termux/proot Ubuntu (aarch64)
# 在手机本地（Termux + proot ubuntu）上构建 APK，构建产物直接落在 sdcard 上
#
# Usage: ./build-termux.sh [debug|release] [full|github|store]
#   默认: debug full
#
# 要求环境：
#   /usr/lib/jvm/java-21-openjdk-arm64    (Gradle 9.4 daemon 用)
#   $HOME/android-sdk                      (含 build-tools/35.0.0 aarch64 + platforms/android-36)
#
# release 签名所需环境变量：
#   STREAMCLIP_KEYSTORE   keystore 路径
#   KEY_ALIAS             key alias（默认 pisces312）
#   KEY_STORE_PASSWORD    keystore 密码
