-This module provides the following common ability-related functions:
-- [Caller](#caller): implements sending of sequenceable data to the target ability when an ability (caller ability) invokes the target ability (callee ability).
-- [Callee](#callee): implements callbacks for registration and deregistration of caller notifications.
+- [Caller](#caller): an object returned by [startAbilityByCall](js-apis-inner-application-uiAbilityContext.md#uiabilitycontextstartabilitybycall). The CallerAbility (caller) uses this object to communicate with the CalleeAbility (callee).

 ## Obtaining the Sandbox Path
-For the FA model, the sandbox path of a bundle can be obtained using the APIs in [Context](js-apis-inner-app-context.md). For the stage model, the sandbox path can be obtained using the attribute in [Context](js-apis-ability-context.md#abilitycontext). The following describes how to obtain the sandbox path.

+# @ohos.file.picker (Picker)
+
+> **NOTE**
+>
+> The initial APIs of this module are supported since API version 9. Newly added APIs will be marked with a superscript to indicate their earliest API version.
+
+**Picker** encapsulates system applications, such as **PhotoViewPicker**, **DocumentViewPicker**, and **AudioViewPicker**, and provides capabilities of selecting and saving images, videos, documents, and audio clips. The application can select the picker as required.
+
+## Modules to Import
+```js
+import picker from '@ohos.file.picker';
+```
+
+## PhotoViewPicker
+
+Provides APIs for selecting and saving images and videos. Before using the APIs of **PhotoViewPicker**, you need to create a **PhotoViewPicker** instance.
+
+**System capability**: SystemCapability.FileManagement.UserFileService
+
+**Example**
+
+```ts
+let photoPicker = new picker.PhotoViewPicker();
+```
+
+### select
+
+select(option?: PhotoSelectOptions) : Promise<PhotoSelectResult>
+
+Selects one or more images or videos in a **photoPicker** page. This API uses a promise to return the result. You can pass in **PhotoSelectOptions** to specify the media type and the maximum number of files to select.
+
+**System capability**: SystemCapability.FileManagement.UserFileService
+
+**Parameters**
+
+| Name | Type   | Mandatory| Description                      |
+| ------- | ------- | ---- | -------------------------- |
+| option | [PhotoSelectOptions](#photoselectoptions) | No  | Options for selecting images or videos.|

+**Return value**
+
+| Type                           | Description   |
+| ----------------------------- | :---- |
+| Promise<[PhotoSelectResult](#photoselectresult)> | Promise used to return information about the images or videos selected.|
+
+**Example**
+
+```ts
+async function example() {
+  try {  
+    let PhotoSelectOptions = new picker.PhotoSelectOptions();
+    PhotoSelectOptions.MIMEType = picker.PhotoViewMIMETypes.IMAGE_TYPE;
+    PhotoSelectOptions.maxSelectNumber = 5;
+    let photoPicker = new picker.PhotoViewPicker();
+    photoPicker.select(PhotoSelectOptions).then((PhotoSelectResult) => {
+      console.info('PhotoViewPicker.select successfully, PhotoSelectResult uri: ' + JSON.stringify(PhotoSelectResult));
+    }).catch((err) => {

 # @system.vibrator (Vibrator)
 
-
 The **Vibrator** module provides APIs for controlling LED lights and vibrators. You can use the APIs to query the LED light list, turn on and off the LED light, query the vibrator list, query the vibrator effect, and trigger and turn off the vibrator.
 
 Misc devices refer to LED lights and vibrators on devices. LED lights are mainly used for indication (for example, indicating the charging state) and blinking (such as tri-colored lights). Vibrators are mainly used in scenarios such as the alarm clock, power-on/off, and incoming call vibration.
 
 
 > **NOTE**
-> - The initial APIs of this module are supported since API version 4. Newly added APIs will be marked with a superscript to indicate their earliest API version.
+> - The initial APIs of this module are supported since API version 3. Newly added APIs will be marked with a superscript to indicate their earliest API version.
 > - The APIs of this module are no longer maintained since API version 8. You are advised to use [`@ohos.vibrator`](js-apis-vibrator.md) instead.
 > - This module requires hardware support and can only be debugged on real devices.
