# Expo MediaLibrary (next)

A library that provides access to the device's media library.
Android, iOS, tvOS, Included in Expo Go

> For the complete documentation index, see [llms.txt](/llms.txt). Use this file to discover all available pages.

`expo-media-library` provides access to the user's media library, allowing apps to read existing images and videos, as well as save new ones.

> On Android, full access to the media library (the main purpose of this package) is allowed only for apps that require broad access to photos. See [details on Google Play's Photo and Video Permissions policy](https://support.google.com/googleplay/android-developer/answer/14115180).

## Installation

```sh
npx expo install expo-media-library
```

If you are installing this in an [existing React Native app](/bare/overview), make sure to [install `expo`](/bare/installing-expo-modules) in your project.

## Usage

Add a new asset from the web

```tsx
import { View, Text } from 'react-native';
import { Image } from 'expo-image';
import { useEffect, useState } from 'react';
import { File, Paths } from 'expo-file-system';
import { Asset, requestPermissionsAsync } from 'expo-media-library/next';

export default function SaveToMediaLibraryExample() {
  const [asset, setAsset] = useState<Asset | null>(null);

  const downloadFile = async () => {
    const url = 'https://picsum.photos/200/300';
    const destinationFile = new File(Paths.cache, 'test_image.jpg');
    if (destinationFile.exists) {
      return destinationFile;
    } else {
      return File.downloadFileAsync(url, destinationFile);
    }
  };

  useEffect(() => {
    const downloadAndSaveAsset = async () => {
      const file = await downloadFile();
      const { status } = await requestPermissionsAsync();
      if (status !== 'granted') {
        return;
      }
      const asset = await Asset.create(file.uri);
      setAsset(asset);
    };

    downloadAndSaveAsset();
  }, []);

  return (
    <View>
      {asset ? (
        <>

| Parameter | Type | Description |
| --- | --- | --- |
| `mediaTypes`(optional) | [MediaTypeFilter[]](#mediatypefilter) | Limits the type(s) of media that the user will be granting access to. By default, a list that shows both photos and videos is presented. |

  

Allows the user to update the assets that your app has access to. The system modal is only displayed if the user originally allowed only `limited` access to their media library, otherwise this method is a no-op.

Returns: `Promise<void>`

A promise that either rejects if the method is unavailable, or resolves to `void`.

> **Note:** This method doesn't inform you if the user changes which assets your app has access to. That information is only exposed by iOS, and to obtain it, you need to subscribe for updates to the user's media library using [`addListener()`](#medialibraryaddlistenerlistener). If `hasIncrementalChanges` is `false`, the user changed their permissions.

### `MediaLibrary (next).requestPermissionsAsync(writeOnly, granularPermissions)`

Supported platforms: Android, iOS, tvOS.

| Parameter | Type | Description |
| --- | --- | --- |
| `writeOnly`(optional) | `boolean` | Whether to request write-only access without read permissions. Defaults to `false`. Default: `false` |
| `granularPermissions`(optional) | [GranularPermission[]](#granularpermission) | A list of [`GranularPermission`](#granularpermission) values. This parameter has an effect only on Android 13 and newer. By default, `expo-media-library` will ask for all possible permissions. When using granular permissions with a custom config plugin configuration, make sure that all the requested permissions are included in the plugin. |

  

Asks the user to grant permissions for accessing media in user's media library.

Returns: `Promise<permissionresponse>`

A promise that fulfils with [`PermissionResponse`](#permissionresponse) object.

## Event Subscriptions

### `MediaLibrary (next).addListener(listener)`

Supported platforms: Android, iOS, tvOS.

| Parameter | Type | Description |
| --- | --- | --- |
| `listener` | (event: [MediaLibraryAssetsChangeEvent](#medialibraryassetschangeevent)) => void | A callback that is fired when any assets have been inserted or deleted from the library. On Android it's invoked with an empty object. On iOS it's invoked with [`MediaLibraryAssetsChangeEvent`](#medialibraryassetschangeevent) object. |

  

Subscribes for updates in user's media library.

Returns: `EventSubscription`

An [`EventSubscription`](#eventsubscription) object that you can call `remove()` on when you would like to unsubscribe the listener.

### `MediaLibrary (next).removeAllListeners()`

Supported platforms: Android, iOS, tvOS.

Removes all listeners.

Returns: `void`

### `GranularPermission`

Supported platforms: Android, iOS, tvOS.

Literal Type: `string`

### `MediaLibraryAssetsChangeEvent`

Supported platforms: Android, iOS, tvOS.

An event emitted when assets in the media library change.

| Property | Type | Description |
| --- | --- | --- |
| deletedAssets(optional) | `string[]` | Supported platforms: iOS. Array of asset IDs (`ph://` URIs) that have been deleted from the library. Only populated when `hasIncrementalChanges` is `true`. |
| hasIncrementalChanges | `boolean` | Whether the media library's changes can be described as incremental changes. `true` indicates the changes are described by the `insertedAssets`, `deletedAssets` and `updatedAssets` values. `false` indicates that the scope of changes is too large and you should perform a full assets reload. On Android this is always `false` because the platform does not provide incremental change details. |
| insertedAssets(optional) | `string[]` | Supported platforms: iOS. Array of asset IDs (`ph://` URIs) that have been inserted to the library. Only populated when `hasIncrementalChanges` is `true`. |
| updatedAssets(optional) | `string[]` | Supported platforms: iOS. Array of asset IDs (`ph://` URIs) that have been updated. Only populated when `hasIncrementalChanges` is `true`. |
