# 本地构建 LSPosed 模块，不依赖 Android SDK / Gradle / 任何额外下载。
# 工具链: javac + keytool + jarsigner(JDK 自带) + D8(jadx 自带) + aapt2(apktool 自带)
#
# 签名说明: jarsigner 只能做 v1 签名，Android 对 targetSdk>=30 强制要求 v2，
# 所以 Manifest 里 targetSdk 固定为 29。LSPosed 模块不受 targetSdk 影响。
#
# module/stubs 是安全中心类的编译桩（TaskItem/LunchAppItem），只进 javac 的 classpath，
# 不进 dex；运行时由注入到安全中心 ClassLoader 的模块代码直接使用安全中心自己的类。
