@exodus/react-native-image-picker 🎆

A React Native module that allows you to select a photo/video from the device library or camera.

Installation

yarn add @exodus/react-native-image-picker

New Architecture

To take advantage of the new architecture run-

iOS

RCT_NEW_ARCH_ENABLED=1 npx pod-install ios

Android

Set newArchEnabled to true inside android/gradle.properties

Pre-Fabric (AKA not using the new architecture)

npx pod-install ios

Post-install Steps

iOS

Add the appropriate keys to your Info.plist depending on your requirement:

Requirement	Key
Select image/video from photos	NSPhotoLibraryUsageDescription
Capture Image	NSCameraUsageDescription
Capture Video	NSCameraUsageDescription & NSMicrophoneUsageDescription

Android

No permissions required (saveToPhotos requires permission check).

Note: This library does not require Manifest.permission.CAMERA, if your app declares as using this permission in manifest then you have to obtain the permission before using launchCamera.

Targeting Android API Levels Below 30

If your app's minSdkVersion is set to below 30 and it does not already include or depend on androidx.activity:activity:1.9.+ or a newer version, you'll need to add the following line to the dependencies section of your app/build.gradle file to ensure support for the backported AndroidX Photo Picker:

dependencies {
    ...
    implementation("androidx.activity:activity:1.9.+")
    ...
}

Additionally, you may need to update your AndroidManifest.xml to trigger the installation of the backported Photo Picker. For reference, you can check the example app's configuration in example/android/app/src/main/AndroidManifest.xml and example/android/app/build.gradle.

For more details, consult the Android documentation on AndroidX Photo Picker: https://developer.android.com/training/data-storage/shared/photopicker
