-- The **queryBundleActiveStates**, **queryBundleStateInfos**, and **queryBundleStateInfoByInterval** APIs used for device usage statistics are system APIs. Before calling these APIs, you need to apply for the **ohos.permission.BUNDLE_ACTIVE_INFO** permission.
-- This permission is not required for calling **queryCurrentBundleActiveStates**, **queryAppUsagePriorityGroup**, and **isIdleState**, which are third-party APIs.
