Expo Configuration

Android - Configure Custom URL Scheme

Add the following to app.json:

app.json

[
  "@react-native-kakao/core",
  {
    "nativeAppKey": "{{native app key}}",
    "android": {
      "forwardKakaoLinkIntentFilterToMainActivity": true
    }
  }
],

This adds an intent-filter to MainActivity so that tapping a KakaoTalk button configured with the app's scheme launches MainActivity.

AndroidManifest.xml

 <activity android:name=".MainActivity" ...>
   ...
   <intent-filter>
     <action android:name="android.intent.action.VIEW"/>
     <category android:name="android.intent.category.DEFAULT"/>
     <category android:name="android.intent.category.BROWSABLE"/>
     <data android:host="kakaolink" android:scheme="kakao{{kakao app key}}"/>
   </intent-filter>
 </activity>
