@ohos.multimedia.systemSoundManager (System Sound Management)

The systemSoundManager module provides basic capabilities for managing system sounds, including setting and obtaining system ringtones and obtaining a player to play the system ringtone.

NOTE

The initial APIs of this module are supported since API version 10. Newly added APIs will be marked with a superscript to indicate their earliest API version.

The APIs provided by this module are system APIs.

System capability: SystemCapability.Multimedia.SystemSound.Core

Name	Value	Description
RINGTONE_TYPE_DEFAULT	0	Default ringtone type.
RINGTONE_TYPE_MULTISIM	1	Multi-SIM ringtone type.

systemSoundManager.getSystemSoundManager

getSystemSoundManager(): SystemSoundManager

Obtains a system sound manager.

System API: This is a system API.

System capability: SystemCapability.Multimedia.SystemSound.Core

Return value

Type	Description
SystemSoundManager	System sound manager obtained.

Example

let systemSoundManagerInstance: systemSoundManager.SystemSoundManager = systemSoundManager.getSystemSoundManager();

SystemSoundManager

Provides APIs to manage system sounds. Before calling any API in SystemSoundManager, you must use getSystemSoundManager to create a SystemSoundManager instance.

setSystemRingtoneUri

setSystemRingtoneUri(context: Context, uri: string, type: RingtoneType, callback: AsyncCallback<void>): void

Sets a URI for the system ringtone. This API uses an asynchronous callback to return the result.

System API: This is a system API.

System capability: SystemCapability.Multimedia.SystemSound.Core

Parameters

Name	Type	Mandatory	Description
context	Context	Yes	Application context.
uri	string	Yes	URI of the system ringtone. For details, see media.AVPlayer.
type	RingtoneType	Yes	Type of the system ringtone.
callback	AsyncCallback<void>	Yes	Callback used to return the result.

Example

import { BusinessError } from '@ohos.base';

let context: Context = this.context;
let uri = 'file://data/test.wav'; // Set the URI of the target ringtone file.
let type: systemSoundManager.RingtoneType = systemSoundManager.RingtoneType.RINGTONE_TYPE_DEFAULT;

systemSoundManagerInstance.setSystemRingtoneUri(context, uri, type, (err: BusinessError) => {
  if (err) {
    console.error(`Failed to set system ringtone uri. ${err}`);
    return;
  }
  console.info(`Callback invoked to indicate a successful setting of the system ringtone uri.`);
});

setSystemRingtoneUri

setSystemRingtoneUri(context: Context, uri: string, type: RingtoneType): Promise<void>

Sets a URI for the system ringtone. This API uses a promise to return the result.

System API: This is a system API.

System capability: SystemCapability.Multimedia.SystemSound.Core

Parameters

Name	Type	Mandatory	Description
context	Context	Yes	Application context.
uri	string	Yes	URI of the system ringtone. For details, see media.AVPlayer.
type	RingtoneType	Yes	Type of the system ringtone.

Return value

Type	Description
Promise<void>	Promise used to return the result.

Example

import { BusinessError } from '@ohos.base';

let context: Context = this.context;
let uri = 'file://data/test.wav'; // Set the URI of the target ringtone file.
let type: systemSoundManager.RingtoneType = systemSoundManager.RingtoneType.RINGTONE_TYPE_DEFAULT;

systemSoundManagerInstance.setSystemRingtoneUri(context, uri, type).then(() => {
  console.info(`Promise returned to indicate a successful setting of the system ringtone uri.`);
}).catch ((err: BusinessError) => {
  console.error(`Failed to set the system ringtone uri ${err}`);
});

getSystemRingtoneUri

getSystemRingtoneUri(context: Context, type: RingtoneType, callback: AsyncCallback<string>): void
