@ohos.app.ability.quickFixManager (quickFixManager)

The quickFixManager module provides APIs for quick fix. With quick fix, you can fix bugs in your application by applying patches, which is more efficient than by updating the entire application.

NOTE

The initial APIs of this module are supported since API version 9. Newly added APIs will be marked with a superscript to indicate their earliest API version. The APIs of this module are system APIs and cannot be called by third-party applications.
