> 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.  
> The APIs of this module can be used only in the FA model.

## Modules to Import

```js
import featureAbility from '@ohos.ability.featureAbility'
```

## Usage

The **Context** object is created in a **featureAbility** and returned through its **getContext()** API. Therefore, you must import the **@ohos.ability.featureAbility** package before using the Context module. An example is as follows:

```js
import featureAbility from '@ohos.ability.featureAbility'
var context = featureAbility.getContext();
context.getOrCreateLocalDir()
```
