#### 权限列表
## 导入模块
**ohos.permission.RUNNING_LOCK permission**
```js
import featureAbility from '@ohos.ability.featureAbility'
import bundle from '@ohos.bundle'
```
#### 导入模块
Context对象是在featureAbility中创建实例，并通过featureAbility的getContext()接口返回，因此在使用Context时，必须导入@ohos.ability.featureAbility库。示例如下：
```
```js
import featureAbility from '@ohos.ability.featureAbility'
import bundle from '@ohos.bundle'
var context = featureAbility.getContext();
context.getOrCreateLocalDir()
```
