• 下载源码（清华源）

    curl https://mirrors.tuna.tsinghua.edu.cn/git/git-repo -o repo
    chmod +x repo
    echo "export REPO_URL='https://mirrors.tuna.tsinghua.edu.cn/git/git-repo'" >> ~/.bashrc
    source ~/.bashrc
    repo init -u https://mirrors.tuna.tsinghua.edu.cn/git/AOSP/platform/manifest -b android-10.0.0_r36 # 下载android10源码
    repo sync -c
    source build/envsetup.sh
    lunch sdk-eng # 设置成sdk构建
  

• 修改Aapt构建文件Android.bp

  • 修改androidfw的构建文件，让它支持静态库构建， frameworks\base\libs\androidfw\Android.bp，target.android.static设置成true
  • 修改Aapt构建文件frameworks\base\tools\aapt\Android.bp，增加：

    cc_library_shared {
        name: "libaapt_shared",
        
        // 系统不允许链接或者缺失函数符号的库改成静态链接
        static_libs: [
            "libandroidfw",
            "libexpat",
            "libziparchive",
            "libbase",
            "libpng",
        ],
    
        // 大多数系统自带动态库
        shared_libs: [
            "libz",
            "liblog",
            "libcutils",
            "libutils",
        ],
        cflags: [
            "-Wno-format-y2k",
            "-Wno-error=implicit-fallthrough",
        ],
    
        srcs: [
            "AaptAssets.cpp",
            "AaptConfig.cpp",

    }
    
    cc_binary {
        name: "aapt_andr",
    
        srcs: ["Main.cpp"],
        use_version_lib: true,
        
        static_libs: [
            "libandroidfw",
            "libexpat",
            "libziparchive",
            "libbase",
            "libpng",
        ],
    
        shared_libs: [
            "libaapt_shared",
            "libz",

            "libcutils",
            "libutils",
        ],
    }

• 构建 make aapt_andr

• 构建其它CPU架构的可执行文件
