50.android 13的PackageManagerService相关的解析部分说明
InitAppsHelper.java 系统预置应用管理器, scanSystemDirs函数负责扫描传递过来的system/system_ext/odm/oem/vendor/product分区下的应用文件进行开机安装。获取其PackagePartitions.java中静态内部类SystemPartition的app目录以及priv-app目录调用InstallPackageHelper进行扫描安装 initNonSystemApps是安装/data/app目录下的app
PackageSessionVerifier.java 安装会话的验证
VerificationParams.java 安装会话的验证。主要是验证版本号差异，
PackageManagerShellCommand.java 继承自ShellCommand pm脚本是通过cmd package "$@" 执行的，其中package代表在ServiceManager注册的服务名
PackageHandler.java 处理分发PackageManager的消息，比如INIT_COPY/POST_INSTALL 其中post_install是安装完成的标志，会调用InstallPackageHelper中的handlePackagePostInstall发出package_addded广播
PackageInstallerSession.java 安装会话的服务端
InstallPackageHelper.java 负责安装流程处理包 负责处理多个安装请求
InstallParams.java 安装参数，带安装参数信息，在收到来自PackageHandler的INIT_COPY的msg时开启安装 该MSG由PackageInstallerSession.java监听PackageSessionVerifier的verify调用时执行onVerificationComplete()方法中的install方法
