    Getting started

    $ npm install @react-native-community/cameraroll --save

    Mostly automatic installation

    $ react-native link @react-native-community/cameraroll && cd ios && pod install

    Manual installation

    iOS

    1. In XCode, in the project navigator, right click LibrariesAdd Files to [your project's name]
    2. Go to node_modules@react-native-community/cameraroll and add RNCCameraroll.xcodeproj
    3. In XCode, in the project navigator, select your project. Add libRNCCameraroll.a to your project's Build PhasesLink Binary With Libraries
    4. Run your project (Cmd+R)<

    Android

    1. Open up android/app/src/main/java/[...]/MainApplication.java
    • Add import com.reactnativecommunity.cameraroll.CameraRollPackage; to the imports at the top of the file
    • Add new CameraRollPackage() to the list returned by the getPackages() method
    1. Append the following lines to android/settings.gradle:
      include ':@react-native-community_cameraroll'
      project(':@react-native-community_cameraroll').projectDir = new File(rootProject.projectDir, 	'../node_modules/@react-native-community/cameraroll/android')
      
    2. Insert the following lines inside the dependencies block in android/app/build.gradle:
        compile project(':@react-native-community_cameraroll')
      

    Migrating from the core react-native module

    This module was created when the CameraRoll was split out from the core of React Native. To migrate to this module you need to follow the installation instructions above and then change you imports from:

    import { CameraRoll } from "react-native";

    to:

    import CameraRoll from "@react-native-community/cameraroll";

    Usage

    CameraRoll provides access to the local camera roll or photo library.

    Permissions

    The user's permission is required in order to access the Camera Roll on devices running iOS 10 or later. Add the NSPhotoLibraryUsageDescription key in your Info.plist with a string that describes how your app will use this data. This key will appear as Privacy - Photo Library Usage Description in Xcode.

    If you are targeting devices running iOS 11 or later, you will also need to add the NSPhotoLibraryAddUsageDescription key in your Info.plist. Use this key to define a string that describes how your app will use this data. By adding this key to your Info.plist, you will be able to request write-only access permission from the user. If you try to save to the camera roll without this permission, your app will exit.

    On Android permission is required to read the external storage. Add below line to your manifest to request this permission on app install.

    <manifest>
    ...
    <uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE"/>
    ...
    <application>
    

    Methods

    Methods

    save()

    Saves the photo or video of a particular type to an album. This function works the same as saveToCameraRoll, but it allows to specify a particular album you want to store the asset to.

    CameraRoll.save(tag, { type, album })

    saveToCameraRoll()

    CameraRoll.saveToCameraRoll(tag, [type]);

    Saves the photo or video to the photo library.

    On Android, the tag must be a local image or video URI, such as "file:///sdcard/img.png".

    On iOS, the tag can be any image URI (including local, remote asset-library and base64 data URIs) or a local video file URI (remote or data URIs are not supported for saving video at this time).

    If the tag has a file extension of .mov or .mp4, it will be inferred as a video. Otherwise it will be treated as a photo. To override the automatic choice, you can pass an optional type parameter that must be one of 'photo' or 'video'.

    Returns a Promise which will resolve with the new URI.

    Parameters:

    Name Type Required Description
    tag string Yes See above.
    type enum('photo', 'video') No Overrides automatic detection based on the file extension.

    deletePhotos()

    CameraRoll.deletePhotos([uri]);

    Requests deletion of photos in the camera roll.

    On Android, the uri must be a local image or video URI, such as "file:///sdcard/img.png".

    On iOS, the uri can be any image URI (including local, remote asset-library and base64 data URIs) or a local video file URI. The user is presented with a dialog box that shows them the asset(s) and asks them to confirm deletion. This is not able to be bypassed as per Apple Developer guidelines.

    Returns a Promise which will resolve when the deletion request is completed, or reject if there is a problem during the deletion. On iOS the user is able to cancel the deletion request, which causes a rejection, while on Android the rejection will be due to a system error.

    Parameters:

    Name Type Required Description
    uri string Yes See above.
