OpenHarmony 5.0.1 Release

Version Description

OpenHarmony 5.0.1 Release continuously improves the capabilities of the standard system, rolling out API 13 via quick iteration. Compared with 5.0.0 Release, OpenHarmony 5.0.1 Release has the following new or enhanced features:

The C API capabilities are enriched, including but not limited to application queries of the application framework, ArkTS node customization, preferences data management, file management, AVSession integration, event notification, and toggle queries for Wi-Fi, Bluetooth, and location features, as well as cellular network-related capability and pasteboard management. Other improvements include camera enhancements with a wider range of shooting modes and optimizations to Web component functionalities.

A more detailed description of the enhancements is as follows:

Application Framework

  • New ArkTS and C APIs are introduced for creating application child processes.

  • C APIs are added to obtain application information like the cache path, file encryption settings, and bundle name.

  • Adjustment of application-level font scaling is supported.

ArkUI

  • C API functionalities are enhanced for custom node attributes and ArkTS capabilities to access custom attributes of any target node.

  • The Navigation component now allows for customizable title bar positions and font styles for main titles and subtitle. The NavDestination component allows you to set the style of the bottom toolbar and control its visibility status.

  • Multiple components have been adapted for aging-friendly design, adjusting font sizes and component dimensions in line with system aging-friendly settings. Involved components include Dialog, SeletTitleBar, SwipeRefresher, SplitLayout, ComposeTitleBar, ExceptionPrompt, TreeView, Filter, GridObjectSortComponent, ProgressButton, ToolBar, and TabTitleBar.

  • The RichEditor component has been enhanced with features such as scrollbar visibility settings, image drag-and-drop support, and a more comprehensive set of shortcut keys.

Bundle Manager

  • New C APIs are added to query the MainElement information.

  • Third-party HAR now supports the retrieval of startup want parameters for launching the host application.

Distributed Data Management

AC APIs are added to obtain, store, and delete preferences key-value data.

File Management

  • C APIs are now available for applications to obtain file names (including extensions) or the names of the last folder based on an URI.

  • Backup and restore are now supported for applications leveraging the application clone feature.

Graphics and Window Manager

Graphics

  • C APIs are added to the Pixelmap module for manipulating the color space.

  • NativeImage now provides APIs to define the default read/write mode and preset sizes for geometric shapes.

  • When a UIAbility transitions to the background, animations with a set number of loops stops and invoke a complete callback, whereas those set to loop indefinitely continues regardless of whether the UIAbility is running in the foreground or background.

Window Manager

System applications can now proactively request focus.

Media

Audio

  • C APIs are added to facilitate basic interaction with AVSession.

  • The error codes in the casting scenario are refined.

  • The device information attributes returned during casting are improved.

Camera

  • General lens control features have been expanded to include lens cleanliness checks, tripod detection, and ring light compensation control.

  • Capabilities specific to foldable screen lenses have been introduced, allowing for the reporting of front and rear lens statuses based on the device's folding state and enabling automatic lens switching.

  • The feature of capturing HDR photos in HEIF format is introduced.

  • Cloud-based enhancements for shooting effects are integrated into the system.

  • The video segmentation feature is supported. After a video recording operating, a video is quickly generated for preview purposes, which is subsequently deleted once a high-quality video is processed and stored in Gallery, thereby optimizing preview performance.

  • The system now supports camera metadata detection, which supports detection and reporting of smiles, human faces, human eyes, cat eyes, and dog eyes.

  • The capability of outputting depth stream and photographic depth data is added.

Image

The picture type is added. The picture type allows the decoding of certain images with special information into multi-image objects. Multi-image object encoding and decoding and primary and secondary image management are supported. It applies to JPEG and HEIC images.

Common Event and Notification

  • C APIs are added to query the notification enabling status and subscribe to and unsubscribe from common events.

  • Applications can now start the system's semi-modal notification setting page.

C APIs are added to query the on/off status of geolocation, initiate and terminate location services, and report locations.

Telephony Service

  • C APIs are added to obtain the camping information of cellular networks, including the network registration status and access mode.

  • C APIs are added to obtain information about the default data SIM card.

Power Supply

  • The system can now obtain the current charging current, introducing the nowCurrent API for this purpose.

  • The airplane mode can be associated with temperature control. You can customize a temperature control policy to enable the device to enter the airplane mode.

  • The WorkSource proxy running lock can assist the resource scheduler in power consumption control.

  • Devices in a low-battery state can now automatically transition to a deeper sleep state (S4) after being woken up from a lighter sleep state (S3), facilitating extended standby periods.

Startup

APIs are provided to query distributionOsApiName to obtain API version information.

ArkCompiler

  • ASON can parse strings and return collections.Map.

  • Template-based TaskPool APIs are optimized to refine return value structures, eliminating the need for explicit type conversion.

Known Issues

Table 4 Known issues

Issue No. Issue Description Impact To Be Resolved By
I9SXZ8 There is a low probability that app freezing occurs in libark_jsruntime.so due to THREAD_BLOCK_6S in the com.ohos.contacts process. The application freezes when you open the Contacts application to query call records. This issue can be resolved by restarting the Contacts application. December 15
IA6RH6 There is a high probability that app freezing occurs in libbtframework.z.so due to THREAD_BLOCK_6S in the com.ohos.settings process. The Settings application might not respond. This issue can be resolved by restarting the Settings application. December 15
IASDWO The sliding frame rate for accessing the Weibo home page through a browser is lower than the specification baseline. Browsing experience is affected. December 15
IAZYOO The RK3568 development board frequently encounters freezing issues during the WuKong comprehensive random pressure testing. The SystemUI process fails to log main thread activities for a long period of time, and the absence of multi-modal event distributions on the lock screen side contributes to this problem. This issue can be resolved by pressing the power button. It has limited impact on users, and therefore no specific workaround is necessary. December 15
IANQF3 There is a high probability that the system restarts during the WuKong pressure test. This issue leads to the device restarting
and is currently not preventable.		 December 15
IB4L3E There is a high probability that app freezing occurs in libcamera_framework.z.so due to LIFECYCLE_TIMEOUT in the com.ohos.camera process. This issue is caused by the camera_host process. Restart the app to resolve the issue. December 15
IAP85P There is a low probability that a process with a low startup priority is terminated preferentially, resulting in a system freeze. This can lead to the application being shut down, but restarting the application can address the issue. December 15
I9SXZ8 There is a low probability that app freezing occurs in libark_jsruntime.so due to THREAD_BLOCK_6S in the com.ohos.contacts process. This issue occurs because the Contacts application is stuck in the windowStage.loadContent() API. Restarting the application can resolve the issue. December 15
IB36B2 There is a low probability that a JS crash occurs in the com.ohos.mms process, and the problem stack is identified as close. This issue may cause the Messaging application to exit unexpectedly. Restarting the application can resolve the issue. December 15
