+# 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'
+```
+## defaultAppMgr.ApplicationType
+
+Enumerates the application types.
+
+**System capability**: SystemCapability.BundleManager.BundleFramework

+
+## defaultAppMgr.isDefaultApplication
+
+isDefaultApplication(type: string): Promise\<boolean>
+
+Checks whether this application is the default application of a system-defined application type. This API uses a promise to return the result.
+
+**System capability**: SystemCapability.BundleManager.BundleFramework
+
+**Parameters**
+
+| Name         | Type    | Mandatory  | Description                                     |
+| ----------- | ------ | ---- | --------------------------------------- |

+
+**Example**
+
+```js
+defaultAppMgr.isDefaultApplication(defaultAppMgr.ApplicationType.BROWSER)
+.then((data) => {
+    console.info('Operation successful. IsDefaultApplication ? ' + JSON.stringify(data));

+});
+```
+
+## defaultAppMgr.isDefaultApplication
+
+isDefaultApplication(type: string, callback: AsyncCallback\<boolean>): void
