Examples

Package management via command line

Install a package:

pm install [packagename]

List installed packages:

pm list

Package management via source code

Install a package:

#include <pm/PackageManager.h>

PackageManager pm;
InstallParam parms;
pm.installPackage(parms);

Get all package information:

#include <pm/PackageManager.h>

PackageManager pm;
std::vector<PackageInfo> pgInfos;
pm.getAllPackageInfo(&pgInfos);

Uninstall a package:

#include <pm/PackageManager.h>

PackageManager pm;
UninstallParam parms;
pm.uninstallPackage(parms);

Core Classes

PackageManager

Header: #include <pm/PackageManager.h>

The facade class for accessing PMS capabilities on the client side. Main operations:

installPackage(InstallParam) — Install an application package
uninstallPackage(UninstallParam) — Uninstall an application package
getAllPackageInfo(std::vector<PackageInfo>*) — Query all installed package information
getPackageInfo(packageName, PackageInfo*) — Query information for a specific package
getAllPackageName(std::vector<std::string>*) — Query all installed package names
getPackageSizeInfo(packageName, ...) — Query package storage usage
clearAppCache(packageName) — Clear application cache
isFirstBoot() — Query whether this is the first boot

Applications typically construct a PackageManager instance and call the above methods directly. Internally it communicates with PackageManagerService via Binder.

PackageManagerService

Header: #include <pm/PackageManagerService.h>

The server-side implementation class of PMS, registered as a system service. It maintains installed package metadata, performs actual install/uninstall operations, and handles permission and signature verification. Developers generally do not use this class directly.

PackageInfo

Header: #include <pm/PackageInfo.h>

A structure describing the metadata of a single installed package. Main fields include:

packageName / name — Package name and application name
version / priority / appType — Version, priority, and application type
installedPath / installTime / size — Installation path, installation time, and storage size
execfile / entry / manifest — Executable file, entry point, and manifest
activitiesInfo / servicesInfo — Internal Activity and Service lists
shasum — Signature digest
userId / isSystemUI — User ID and whether it is a system UI
windowEnterAnim / windowExitAnim — Window enter/exit animation configuration

Query interfaces of PackageManager return results of this type.

PackageTrace

Header: #include <PackageTrace.h>

A collection of trace macros for PMS, used to trace package management operation paths. Works with openvela trace tools for performance analysis.
