<resources>
  <!-- Existing strings ... -->
  <string name="facebook_app_id">YOUR_FB_APP_ID</string>

4. Add the following to your android/app/src/main/AndroidManifest.xml file (as is, don't replace anything):

<manifest ...>
  <application ...>
    <!-- Existing data ... -->

    <!-- Facebook App ID and Client Token -->
    <meta-data
        android:name="com.facebook.sdk.ApplicationId"
        android:value="@string/facebook_app_id" />
    <meta-data
        android:name="com.facebook.sdk.ClientToken"
        android:value="@string/facebook_client_token" />
    <meta-data android:name="com.facebook.sdk.AutoInitEnabled" android:value="true"/>

</manifest>

5. Add or update your ios/App/App/AppDelegate.swift with the following (as is, don't replace anything):

import FBSDKCoreKit

@UIApplicationMain
class AppDelegate: UIResponder, UIApplicationDelegate {
  var window: UIWindow?

    func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {
        // Initialize the Facebook SDK (reads FacebookAppID from Info.plist)
        ApplicationDelegate.shared.application(application, didFinishLaunchingWithOptions: launchOptions)

        Settings.shared.isAutoLogAppEventsEnabled = true
        Settings.shared.isAdvertiserIDCollectionEnabled = true

        // Uncomment this to enable verbose output of Facebook SDK to XCode console
        /* Settings.shared.loggingBehaviors = Set([
            .appEvents, .networkRequests, .informational,
            .graphAPIDebugInfo, .graphAPIDebugWarning, .developerErrors
        ]) */

        return true
    }

    func applicationDidBecomeActive(_ application: UIApplication) {
      // Sends the built-in "Activate App" event (shows in Test Events)
      AppEvents.shared.activateApp()
    }
}
