 With device usage statistics APIs, you can have a better understanding of the application, notification, and system usage. For example, in application usage statistics, you can query the application usage, event log, and bundle group.

+# DefaultAppManager
+
+The **DefaultAppManager** module provides APIs to query whether the current application is the default application of a specific type.
+
+> **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.
+
+## Modules to Import
+
+```
+import defaultAppMgr from '@ohos.bundle.defaultAppManager'
