Resource Scheduler Subsystem Changelog

c1.resource schedule.1 Background Application Control Changed

Access Level

Other

Change Reason

After the continuous task of an audio playback application is stopped, the application still plays audio streams, affecting system running.

Change Impact

Applications that use audio resources improperly in the background will be forcibly terminated by the system.

Start API Level

Change Since

OpenHarmony SDK 5.0.0.22

Key API/Component Changes

Before the change: If the audio stream type is STREAM_USAGE_MEDIA or SREAM_USAGE_UNKNOWN, the application will be forcibly terminated by the system.

After the change: The system forcibly terminates the application regardless of the audio stream type used by the application.

Change plan: In this version, the log “Audio cannot be used after being frozen. The system will kill the UID” will be recorded. From the next version, the application will be forcibly terminated.

Adaptation Guide

To use audio resources in the background, an application must request a continuous task. When it no longer requires the audio resources, it should release the continuous task and audio resources in a timely manner.

For details about how to request a continuous task, refer to the following guide: https://gitee.com/openharmony/docs/blob/master/en/application-dev/task-management/continuous-task.md
