[-> VirtualCore : installApp

VirtualCore -> VAppManagerService : installApp
activate VAppManagerService

    VAppManagerService -> VAppManagerService: install
    activate VAppManagerService
        VAppManagerService -> PackageParserCompat : parsePackage
        activate PackageParserCompat
        deactivate PackageParserCompat

        note over VAppManagerService
        接下来创建client应用需要的相关数据结构，并在VA的data目录下
        为client创建data目录，与系统中该应用的data目录隔离
        endnote

        VAppManagerService -> VEnvironment : getDataAppPackageDirectory(pkg.packageName)
        activate VEnvironment
        deactivate VEnvironment

        VAppManagerService -> NativeLibraryHelperCompat : copyNativeBinaries
        activate NativeLibraryHelperCompat
        deactivate NativeLibraryHelperCompat

        VAppManagerService -> AppSetting : new AppSetting()
        activate AppSetting
        VAppManagerService <-- AppSetting : appSetting:AppSetting

        note over VAppManagerService
        接下来构造AppSetting数据结构，其中包括：
        String packageName;
        String apkPath;
        String libPath;
        String odexDir;
        boolean dependSystem;
        int appId;
        public PackageParser parser;
        endnote

        deactivate AppSetting

        VAppManagerService -> StaticBroadcastSystem : startApp
        note over StaticBroadcastSystem
        在这里处理client的静态广播接收器，核心思想是对Clientd每个
        static broadcast receiver分别注册一个动态广播接收器到VA
        应用（VA服务进程）。
        注意，VA会修改receiver的IntentFilter的ACTION。
        并且在这里设计了黑名单机制过滤ACTION。
        endnote
        activate StaticBroadcastSystem
        deactivate StaticBroadcastSystem

        VAppManagerService -> VAppManagerService : notifyAppInstalled
        activate VAppManagerService
        deactivate VAppManagerService

    deactivate VAppManagerService

VirtualCore <-- VAppManagerService
deactivate VAppManagerService

[<- VirtualCore
deactivate VirtualCore
