Permissions

iOS

ios/Podfile

  target 'routine' do
    config = use_native_modules!

    permissions_path = '../node_modules/react-native-permissions/ios'
    pod 'Permission-PhotoLibrary', :path => "#{permissions_path}/PhotoLibrary/Permission-PhotoLibrary.podspec"

    ...

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.

Android

Permission is required to read and write to the external storage.

On Expo, follow the guide here for requesting the permission.

On react-native-cli or ejected apps, adding the following lines will add the capability for the app to request the permission. Find more info on Android Permissions here.

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