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

Name Type Description
BROWSER string Default browser.
IMAGE string Default image viewer.
AUDIO string Default audio player.
VIDEO string Default video player.
PDF string Default PDF reader.
WORD string Default Word viewer.
EXCEL string Default Excel viewer.
PPT string Default PowerPoint viewer.

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
type string Yes Type of the target application. It must be set to a value defined by ApplicationType.

Return value

Type Description
Promise<boolean> Promise used to return the result. If the application is the default application, true is returned; otherwise, false is returned.

Example

defaultAppMgr.isDefaultApplication(defaultAppMgr.ApplicationType.BROWSER)
.then((data) => {
    console.info('Operation successful. IsDefaultApplication ? ' + JSON.stringify(data));
}).catch((error) => {
    console.error('Operation failed. Cause: ' + JSON.stringify(error));
});

defaultAppMgr.isDefaultApplication

isDefaultApplication(type: string, callback: AsyncCallback<boolean>): void

Checks whether this application is the default application of a system-defined application type. This API uses an asynchronous callback to return the result.

System capability: SystemCapability.BundleManager.BundleFramework

Parameters

Name Type Mandatory Description
type string Yes Type of the target application. It must be set to a value defined by ApplicationType.
callback AsyncCallback<boolean> Yes Callback used to return the result. If the application is the default application, true is returned; otherwise, false is returned.

defaultAppMgr.isDefaultApplication(defaultAppMgr.ApplicationType.BROWSER, (err, data) => {
    if (err) {
        console.error('Operation failed. Cause: ' + JSON.stringify(err));
        return;
    }
    console.info('Operation successful. IsDefaultApplication ? ' + JSON.stringify(data));
 });

defaultAppMgr.getDefaultApplication

getDefaultApplication(type: string, userId?: number): Promise<BundleInfo>

Obtains the default application based on a system-defined application type or a file type that complies with the media type format (either specified by type or subtype). This API uses a promise to return the result.

Required permissions: ohos.permission.GET_DEFAULT_APPLICATION

System capability: SystemCapability.BundleManager.BundleFramework
