+## Modules to Import
+
+```js
+import featureAbility from '@ohos.ability.featureAbility'
+import bundle from '@ohos.bundle'
+```
+
+The **Context** object is created in a **featureAbility** and returned through its **getContext()** method. 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()
+```
+
+## Context.getOrCreateLocalDir(callback: AsyncCallback<string>)
+
