        jcenter()
        maven { url 'https://devrepo.kakao.com/nexus/content/groups/public/' }
    }
}

• Add Kakao Initialization

public class MainActivity extends BridgeActivity {
    private CallbackManager callbackManager;

    @Override
    public void onCreate(Bundle savedInstanceState) {
      super.onCreate(savedInstanceState);
      // 카카오
+      KakaoSdk.init(this, getString(R.string.kakao_app_key);
    }
}

• Add kakao string variables

<string name="kakao_app_key">{NATIVE_APP_KEY}</string>
<string name="kakao_scheme">kakao{NATIVE_APP_KEY}</string>

IOS

• Add kakao values and schemes to info.plist

<dict>
  <array>
     <dict>
	<key>CFBundleURLSchemes</key>
   	<array>
	    <string>kakao{NATIVE_APP_KEY}</string>
	</array>
     </dict>

     <string>kakaolink</string>
     <string>storylink</string>
     <string>kakaotalk</string>
  </array>
</dict>

• Add initial kakao codes to AppDelegate.swift

import UIKit
import Capacitor
import KakaoSDKAuth
import KakaoSDKCommon

@UIApplicationMain
class AppDelegate: UIResponder, UIApplicationDelegate {
  
  ...
  
  func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {
        // Override point for customization after application launch.
    
    	// Initialize Kakao
+       let key = Bundle.main.infoDictionary?["KAKAO_APP_KEY"] as? String
+       KakaoSDK.initSDK(appKey: key!)
        return true
  }
  
  ...
  
  func application(_ app: UIApplication, open url: URL, options: [UIApplication.OpenURLOptionsKey: Any] = [:]) -> Bool {
        // Called when the app was launched with a url. Feel free to add additional processing here,
        // but if you want the App API to support tracking app url opens, make sure to keep this call
    
    	// Need for Login with KakaoTalk
+       if (AuthApi.isKakaoTalkLoginUrl(url)) {
+           return AuthController.handleOpenUrl(url: url)
+       }
        
        return ApplicationDelegateProxy.shared.application(app, open: url, options: options)
  }
  
  ...
}
