# @ohos.resourceManager (Resource Manager)

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';

export default class EntryAbility extends UIAbility {
    onWindowStageCreate(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.

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

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

**Parameters**

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

**Example**
  ```js
  resourceManager.getResourceManager((error, mgr) => {
      if (error != null) {
          console.log("error is " + error);
          return; 
      }
      mgr.getString(0x1000000, (error, value) => {
          if (error != null) {
              console.log("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.
