# Resource Manager

The Resource Manager 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';
```

## Instruction

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 details about how to reference **context** in the stage model, see [Context in the Stage Model].

```ts
import Ability from '@ohos.application.Ability';
class MainAbility extends Ability {
    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.

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

**Example**
  ```js
  resourceManager.getResourceManager((error, mgr) => {
      if (error != null) {

          return; 
      }
      mgr.getString(0x1000000, (error, value) => {
          if (error != null) {

### getRawFile<sup>(deprecated)</sup>

getRawFile(path: string, callback: AsyncCallback&lt;Uint8Array&gt;): void

Obtains the content of the raw file in the **resources/rawfile** directory. This API uses an asynchronous callback to return the result.

This API is deprecated since API version 9. You are advised to use [getRawFileContent](#getrawfilecontent9) instead.

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

**Parameters**

| Name     | Type                             | Mandatory  | Description                     |
| -------- | ------------------------------- | ---- | ----------------------- |
| path     | string                          | Yes   | Path of the raw file.            |
| callback | AsyncCallback&lt;Uint8Array&gt; | Yes   | Callback used to return the result.|

**Example**
  ```ts
  resourceManager.getResourceManager((error, mgr) => {
      mgr.getRawFile("test.xml", (error, value) => {
          if (error != null) {
              console.log("error is " + error);
          } else {
              let rawFile = value;
          }
      });
  });
  ```


### getRawFile<sup>(deprecated)</sup>

getRawFile(path: string): Promise&lt;Uint8Array&gt;

Obtains the content of the raw file in the **resources/rawfile** directory. This API uses a promise to return the result.

This API is deprecated since API version 9. You are advised to use [getRawFileContent](#getrawfilecontent9-1) instead.

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

**Parameters**

| Name | Type    | Mandatory  | Description         |
| ---- | ------ | ---- | ----------- |
| path | string | Yes   | Path of the raw file.|

**Return value**
| Type                       | Description         |
| ------------------------- | ----------- |
| Promise&lt;Uint8Array&gt; | Promise used to return the result.|

**Example**
  ```ts
  resourceManager.getResourceManager((error, mgr) => {
      mgr.getRawFile("test.xml").then(value => {
          let rawFile = value;
      }).catch(error => {
          console.log("getRawFile promise error is " + error);
      });
  });
  ```


### getRawFileDescriptor<sup>(deprecated)</sup>

getRawFileDescriptor(path: string, callback: AsyncCallback&lt;RawFileDescriptor&gt;): void

Obtains the descriptor of the raw file in the **resources/rawfile** directory. This API uses an asynchronous callback to return the result.

This API is deprecated since API version 9. You are advised to use [getRawFd](#getrawfd9) instead.

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

**Parameters**

| Name     | Type                                      | Mandatory  | Description                              |

| path     | string                                   | Yes   | Path of the raw file.                     |
| callback | AsyncCallback&lt;[RawFileDescriptor](#rawfiledescriptor8)&gt; | Yes   | Callback used to return the result.|

**Example**
  ```ts
  resourceManager.getResourceManager((error, mgr) => {
      mgr.getRawFileDescriptor("test.xml", (error, value) => {
          if (error != null) {
              console.log("error is " + error);
          } else {
              let fd = value.fd;
              let offset = value.offset;
              let length = value.length;
          }
      });
