JS API 7 new interface

JS API 7 adds nearly 6000 interfaces , covering distributed data management subsystem, telephone service subsystem, image and graphics subsystem, etc., allowing developers to develop fully functional user applications through JS API.

JS API 7 focuses on adding the following 4 interfaces:

The new interface of the public basic library: including the capabilities of Parcel, URL, and codec library.

New window/webgl interface for graphics and image subsystem: Provides the basic capabilities of WebGL rendering. Developers can develop games and window applications based on WebGL. The new interface of the telephone service subsystem: Provides telephone service capabilities based on the cellular network, including various modules such as SIM card, network search, SMS, cellular data, call management, and network management.

The new interface of the multimedia subsystem: It mainly includes media capabilities such as audio and video, media library, image codec, etc., which supports the commercial appeal of X1 Gallery, and simultaneously helps HarmonyOS’s northward ecological expansion.
