CarPackageManagerService is mainly used in car usage scenarios and expands some package management-related interfaces. Including the black and white list mechanism, which is mainly for security reasons, the application in the car has stricter restrictions. Combined with user experience constraints, there is a better constraint for applications running on Android Automotive OS.
1. Introduction
CarPackageManagerService is a key component of the Android Automotive platform that manages the installation, uninstallation, and management of in-car applications. Compared with the traditional PackageManagerService, CarPackageManagerService differs in the following aspects:
Car application management: CarPackageManagerService specializes in the management of car applications. It provides functionality specific to the vehicle environment, such as automatically managing the availability of applications based on vehicle status (e.g. driving state, parked state), limiting the operation of applications, or displaying specific in-vehicle applications.
Security and permission management: CarPackageManagerService provides special handling of security and permission management in the automotive environment. It restricts access to in-vehicle applications, ensuring only authorized applications can access specific vehicle functions and sensitive information.
User interface adaptation: CarPackageManagerService provides specialized interface adaptation functions to adapt to the display and input requirements of the vehicle. It can display a user interface suitable for driving scenarios on the in-vehicle screen and support specific input devices in the vehicle, such as buttons, dials or touch screens.
Car application updates: CarPackageManagerService supports automatic updates of in-car applications. It can control the automatic update policy of applications based on device settings to ensure that vehicle systems always use the latest application versions.
