Yesterday OpenHarmony 3.2 Beta 3 version was released for the developers. The version is based on Beta 2 and comes with the following three improvements.

  • Extension of basic capabilities of standard systems
  • Extension of the framework for the development of standard system applications
  • Improved distributed capabilities of traditional systems

Check out the full OpenHarmony 3.2 Beta 3 details below.

Extension of basic capabilities of standard systems:

The pan sensor offers a motor priority management function. Multimode input provides features such as mouse style and speed settings, mouse notification event enhancements, application launch configuration sequences, and keyboard and mouse traversal.

Misc service adds basic module functionality like clipboard, upload and download, screen lock and input method framework.

The kernel subsystem adds memory pressure notifications to AMS, recycling priority management to support resident system services, and recycling priority management to support basic capabilities such as B. Differentiation of the extension status.

DFX supports mixed JS/native stack printing with faultloggerd, whitelist management of hilog domains and log statistics functions, advanced hisysevent and hiappeventssh event functions, and optimized hidumper memory classification information.

The unit testing framework added parameterized data-driven functions, the UI testing framework added the interface for throwing and complex gestures like two-finger pinch functions. Xdevice added the ability to collect device DXF logs after task execution is complete.

Added support for ES2021 in strict mode, modular support, runtime debugging and optimization improvements, bytecode hot reloading, cross-platform support, etc. when compiling and running.

Account service added a user identity authentication service. The authority service has added support for precise positioning or fuzzy positioning, and other features have been improved and a privacy management service has been added.

The media subsystem supports audio decoding, audio encoding, video decoding, native video encoding interface, supports playback audio and video synchronization and boot time optimization, supports video hardware encoding and decoding functions based on the HDI codec interface, supports distributed audio, volume, device status management, device monitoring and transmission functions, support for distributed camera preview, photo and video recording.

Extensions of the framework for the development of standard system applications:

Added DLP for events and notifications, added support for sending notifications from subsystems.

Supports web view copy and paste, supports basic audio and video playback, supports two-way HTTPS authentication and other functions.

Meta-capacity has added permissions checking and rectification, starting rules, quick repairs, and maps that can be split and combined.

Improved ArkUI component capabilities, expanded resource and media query capabilities, optimized memory and performance, DFX capabilities, and enhanced toolchain capabilities.

DeviceProfile adapts to the automatic synchronization strategy of distributed databases and completes the collection of information.

Package management added support for thumbnails and preview extensions. Some features have additional support for clipping configuration, foolproof mechanism and default application-specific skill management. The installation process supports the hap package without decompression and supports a fast repair mechanism.

System service management supports cross-device loading of system services, restarting of basic processes and recovery mechanisms, distributed component management supports cross-device multi-user calls, and the migration framework supports single-instance-ability migration.

Improved distributed capabilities of standard systems

Distributed database supports cross-device and cross-application sharing, RDB supports remote query/database encryption capabilities, and supports application avatars. KVDB supports backup recovery/conditional synchronization/device online priority and centralized synchronization of system data.
