AbilityDelegator

The AbilityDelegator module provides APIs for managing AbilityMonitor instances that are used to monitor the lifecycle state changes of a specified ability. You can use the APIs to add and remove AbilityMonitor instances, wait for an ability to reach the onCreate lifecycle state, set the waiting time, obtain the lifecycle state of an ability, obtain the top ability of the current application, and start an ability.

NOTE

The initial APIs of this module are supported since API version 8. Newly added APIs will be marked with a superscript to indicate their earliest API version.

Modules to Import
