@ohos.wantAgent (WantAgent)

The WantAgent module provides APIs for creating and comparing WantAgent objects, and obtaining the user ID and bundle name of a WantAgent object.

NOTE

The APIs of this module are supported since API version 7 and deprecated since API version 9. You are advised to use @ohos.app.ability.wantAgent instead. Newly added APIs will be marked with a superscript to indicate their earliest API version.

Modules to Import

import WantAgent from '@ohos.wantAgent';

WantAgent.getWant

getWant(agent: WantAgent, callback: AsyncCallback<Want>): void

Obtains the Want in a WantAgent object. This API uses an asynchronous callback to return the result.

System capability: SystemCapability.Ability.AbilityRuntime.Core

System API: This is a system API and cannot be called by third-party applications.

Parameters

agent WantAgent Yes WantAgent object.
callback AsyncCallback<Want> Yes Callback used to return the Want.

Example

import WantAgent, { WantAgent as _WantAgent} from '@ohos.wantAgent';
import Want from '@ohos.app.ability.Want';

WantAgent.equal

equal(agent: WantAgent, otherAgent: WantAgent, callback: AsyncCallback<boolean>): void

Checks whether two WantAgent objects are equal to determine whether the same operation is from the same application. This API uses an asynchronous callback to return the result.

System capability: SystemCapability.Ability.AbilityRuntime.Core

Parameters

Name Type Mandatory Description
agent WantAgent Yes The first WantAgent object.
otherAgent WantAgent Yes The second WantAgent object.
callback AsyncCallback<boolean> Yes Callback used to return the result.

Example

import WantAgent, { WantAgent as _WantAgent} from '@ohos.wantAgent';
import { BusinessError } from '@ohos.base';

// WantAgent object
let wantAgent1: _WantAgent;
let wantAgent2: _WantAgent;

// getWantAgent callback
function getWantAgentCallback(err: BusinessError, data: _WantAgent) {
	console.info('==========================>getWantAgentCallback=======================>');
    if (err.code == 0) {
    	wantAgent1 = data;
        wantAgent2 = data;
    } else {
        console.error('getWantAgent failed, error: ' + JSON.stringify(err));
        return;
    }

    // equal callback
    let equalCallback = (err: BusinessError, data: boolean) => {
        console.info('==========================>equalCallback=======================>');
    }
    WantAgent.equal(wantAgent1, wantAgent2, equalCallback)
}

WantAgent.getWantAgent({
    wants: [
        {
            deviceId: 'deviceId',
            bundleName: 'com.neu.setResultOnAbilityResultTest1',

    ],
    operationType: WantAgent.OperationType.START_ABILITIES,
    requestCode: 0,
    wantAgentFlags:[WantAgent.WantAgentFlags.UPDATE_PRESENT_FLAG]
}, getWantAgentCallback)

WantAgent.equal

equal(agent: WantAgent, otherAgent: WantAgent): Promise<boolean>

Checks whether two WantAgent objects are equal to determine whether the same operation is from the same application. This API uses a promise to return the result.

System capability: SystemCapability.Ability.AbilityRuntime.Core

Parameters

Name Type Mandatory Description
agent WantAgent Yes The first WantAgent object.
otherAgent WantAgent Yes The second WantAgent object.

Return value

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

	console.info('==========================>getWantAgentCallback=======================>');
    wantAgent1 = data;
    wantAgent2 = data;
    if (data) {
        WantAgent.equal(wantAgent1, wantAgent2).then((data) => {
