@ohos.app.ability.application (Application) (System API)

You can use this module to create a Context.

NOTE

The initial APIs of this module are supported since API version 12. Newly added APIs will be marked with a superscript to indicate their earliest API version. The APIs of this module can be used only in the stage model.

Modules to Import

import { application } from '@kit.AbilityKit';

application.createModuleContext¹²⁺

createModuleContext(context: Context, bundleName: string, moduleName: string): Promise<Context>

Creates the context for a module.

NOTE

• Since API version 18, the context can obtain the process name of the current application. The processName property in the context created by createModuleContext is the same as the processName property in the input parameter Context. The values of other properties are obtained based on the input parameters Context, bundleName, and moduleName.

• This API requires multiple bundle information queries and loads all resources of the specified module, which can be quite slow. To optimize performance, you are advised to cache the created context during the first use to prevent repeated calls for context creation.

Atomic service API: This API can be used in atomic services since API version 12.

System capability: SystemCapability.Ability.AbilityRuntime.Core

System API: This is a system API.

        console.info('createModuleContext success!');
