# @ohos.resourceManager (Resource Management)

The **resourceManager** module provides APIs to obtain information about application resources based on the current configuration, including the language, region, screen direction, MCC/MNC, as well as device capability and density.

> **NOTE**
>
> The initial APIs of this module are supported since API version 6. Newly added APIs will be marked with a superscript to indicate their earliest API version.

## Modules to Import

```js
import resourceManager from '@ohos.resourceManager';
```

## How to Use

Since API version 9, the stage model allows an application to obtain a **ResourceManager** object based on **context** and call its resource management APIs without first importing the required bundle. This approach, however, is not applicable to the FA model. For the FA model, you need to import the required bundle and then call the [getResourceManager](#resourcemanagergetresourcemanager) API to obtain a **ResourceManager** object.
For details about how to reference context in the stage model, see [Context in the Stage Model](../../application-models/application-context-stage.md).

```ts
import UIAbility from '@ohos.app.ability.UIAbility';
import window from '@ohos.window';

export default class EntryAbility extends UIAbility {
  onWindowStageCreate(windowStage: window.WindowStage) {
    let context = this.context;
    let resourceManager = context.resourceManager;
  }
}
```

## resourceManager.getResourceManager

getResourceManager(callback: AsyncCallback<ResourceManager>): void

Obtains the **ResourceManager** object of this application. This API uses an asynchronous callback to return the result.

**System capability**: SystemCapability.Global.ResourceManager

**Model restriction**: This API can be used only in the FA model.

**Parameters**

| Name     | Type                                      | Mandatory  | Description                           |
| -------- | ---------------------------------------- | ---- | ----------------------------- |
| callback | AsyncCallback<[ResourceManager](#resourcemanager)> | Yes   |Callback used to return the result, which is a **ResourceManager** object.|

**Example**
  ```js
  resourceManager.getResourceManager((error, mgr) => {
    if (error != null) {
      console.error("error is " + error);
      return;
    }
    mgr.getStringValue(0x1000000, (error: BusinessError, value: string) => {
      if (error != null) {
        console.error("error is " + error);
      } else {
        let str = value;
      }
    });
  });
  ```
> **NOTE**<br>In the sample code, **0x1000000** indicates the resource ID, which can be found in the compiled **ResourceTable.txt** file.

> **NOTE**
>
> - The methods involved in **ResourceManager** are applicable only to the TypeScript-based declarative development paradigm.
>
> - Resource files are defined in the **resources** directory of the project. You can obtain the resource ID using **$r(resource address).id**, for example, **$r('app.string.test').id**.
>
> - You can use **.context().resourceManager** to access intra-package resources in an application by resource ID or resource name.
>
> - For cross-package resources within an application, two methods are available for accessing a resource:
by way of a resource object or by creating the context of the corresponding module and accessing the resource through **.context().createModuleContext().resourceManager**.
>
> - For cross-application package resources, use **.context.createModuleContext(bundleName:'bundleName name',moduleName:'module name').resourceManager**. This API can be used only by system applications.
>
> - For details about **Context**, see [Context (Stage Model)] (../../application-models/application-context-stage.md).
