@ohos.bundleState (Device Usage Statistics) (System API)

This module provides APIs for collecting statistics on device usage.

System applications can call these APIs to implement the following features:

Query the usage duration in different time segments, events (foreground, background, start and end of continuous tasks), and the number of notifications, on a per application basis.
Query the bundle group information of the invoking application itself.
Query the idle status of applications, including the invoking application itself.

NOTE

This module is deprecated since API version 9. You are advised to use @ohos.resourceschedule.usageStatistics (Device Usage Statistics) (System API) instead.

The initial APIs of this module are supported since API version 7. Newly added APIs will be marked with a superscript to indicate their earliest API version.

This topic describes only system APIs provided by the module. For details about its public APIs, see @ohos.bundleState.
