- 不试图改变项目本身的目录结构
- 通过添加额外的配置和依赖构建Gradle环境支持
- 会使用脚本移除一些AS不支持的属性和字段，然后利用git本地忽略
- 运行的效果会与原生的还是有些许差异，这是由于脱离源码之后，引用private属性失败所导致的样式差异（如下图）

将具体路径下的代码直接导入到项目中作为Module依赖, 构建的时候可以直接通过implementation project引用，或者也可以gradle build生成aar,再放置到libs文件夹中，作为静态包使用。

在AOSP/android-11/build/target/product/security路径下找到签名证书，并使用 keytool-importkeypair 生成keystore, 执行如下命令：
./keytool-importkeypair -k platform.keystore -p 123456 -pk8 platform.pk8 -cert platform.x509.pem -alias platform
并将以下代码添加到gradle配置中：
signingConfigs {
platform {
storeFile file("platform.keystore")
storePassword '123456'
keyAlias 'platform'
keyPassword '123456'
}
}
buildTypes {
release {
debuggable false
minifyEnabled false
signingConfig signingConfigs.platform
}
debug {
debuggable true
minifyEnabled false
signingConfig signingConfigs.platform
}
}
