Samples

The following samples written in ArkTS are added.

Table 4 New samples

Subsystem	Name	Introduction
Common event and notification subsystem	Event Notification	This sample shows the in-process event notification. After a user selects an offering and submits an order, the selected offering is displayed in the order list.
Data management subsystem	Cross-Application Data Sharing	This sample implements cross-application data sharing. It provides contacts (data provider) and contacts assistant (data user). Contacts support functionalities such as adding, deleting, modifying, and querying contacts data. Contacts assistant supports contacts data synchronization and merging of duplicate data.
Resource scheduler subsystem	Agent-Powered Scheduled Reminder	This sample uses agent-powered scheduled reminder to create three types of scheduled reminders: alarm clocks, calendar events, and countdown timers. Agent-powered scheduled reminder ensures that the timing and pop-up notification functions will be performed by the system service agent in the background when the application is frozen or exits.
File management subsystem	Storage Space Statistics	This sample uses the application package management, application space statistics, and volume management modules to implement the viewing of storage space information of the current device, all installed applications, and all available volumes.
Window manager	Screenshot	This sample uses the screenshot, window, and display modules to take screenshots, switch the privacy window, and query the privacy window, in sequence.
Bundle management framework	Multi-HAP	This sample shows the development of multi-HAP. The sample app includes one entry HAP and two feature HAPs. The two feature HAPs provide audio and video playback components, respectively. The two components are also used in the entry component.
Ability framework	Ability Launch Mode	This sample shows how to implement the standard, singleton, and specified ability launch modes in the stage model.
Resource management	Application Theme Switch	This sample creates the dark and light folders at the same level as the base folder to configure resources related to the dark and light themes. The custom theme file is configured in the ThemeConst file to implement multi-theme switching by controlling variables.
