OpenHarmony 3.1.1 Release

Version Description

OpenHarmony 3.1.1 Release provides the following enhancements over OpenHarmony 3.1 Release:

Enhanced basic capabilities for the standard system

System service management is enhanced to support group verification. Power management now supports brightness adjustment and battery information query. The Misc services subsystem supports HTTP file download APIs.

The location service subsystem now implements basic positioning APIs. The window manager subsystem supports setting of window properties. The multimedia subsystem provides APIs related to audio focus and audio decoding.

Network management supports Ethernet connections. WebSocket JS APIs are added, which are compatible with the \@system.fetch and \@system.network APIs.

Enhanced distributed capabilities for the standard system

Distributed data management is now compatible with the \@system.storage APIs.

Enhanced application framework capabilities for the standard system

Bundle management supports application-specific installation status query. The common event and notification subsystem provides APIs for sending and canceling notifications.

The Feature Ability (FA) model supports ability-level screen orientation query and setting, lock screen display, and screen-on during ability startup. DFX features, such as Application Not Response and suspension detection for an application’s main thread, are added. More basic capabilities are added for FA widgets.

Enhanced application capabilities for the standard system

The Contacts application allows third-party applications to invoke the system call capability, so end users can use the basic communication capabilities of devices.
