Installation in bare React Native projects

For bare React Native projects, you must ensure that you have installed and configured the expo package before continuing.

Add the package to your npm dependencies

npm install -S @adesso-gcc/expo-camera

Configure for iOS

Add NSCameraUsageDescription and NSMicrophoneUsageDescription keys to your Info.plist:

<key>NSCameraUsageDescription</key>
<string>Allow $(PRODUCT_NAME) to use the camera</string>
<key>NSMicrophoneUsageDescription</key>
<string>Allow $(PRODUCT_NAME) to use the microphone</string>

Run npx pod-install after installing the npm package.

Configure for Android

This package automatically adds the CAMERA permission to your app. If you want to record videos with audio, you have to include the RECORD_AUDIO.

<!-- Added permissions -->
<uses-permission android:name="android.permission.CAMERA" />

<!-- Optional permissions -->
<uses-permission android:name="android.permission.RECORD_AUDIO" />

Adjust the android/build.gradle to add a new maven block after all other repositories as described below:

allprojects {
    repositories {

        // * Your other repositories here *

        // * Add a new maven block after other repositories / blocks *
        maven {
            // expo-camera bundles a custom com.google.android:cameraview
            url "$rootDir/../node_modules/expo-camera/android/maven"
        }
    }
}

The sourcecode for cameraview can be found at expo/cameraview.
