2. GlobalApplication.kt 파일 생성 후 작성

import android.app.Application
import com.kakao.auth.KakaoSDK

class GlobalApplication : Application() {
    override fun onCreate() {
        super.onCreate()

        instance = this
        KakaoSDK.init(KakaoSDKAdapter())
    }

    override fun onTerminate() {
        super.onTerminate()
        instance = null
    }

    fun getGlobalApplicationContext(): GlobalApplication {
        checkNotNull(instance) { "this application does not inherit com.kakao.GlobalApplication" }
        return instance!!
    }

    companion object {
        var instance: GlobalApplication? = null
    }
}

 

 

 

 

3. KakaoSDKAdapter.kt 파일 생성 후 작성

import com.kakao.auth.*

open class KakaoSDKAdapter : KakaoAdapter() {
    override fun getSessionConfig(): ISessionConfig {
        return object : ISessionConfig {
            override fun getAuthTypes(): Array<AuthType> {
                return arrayOf(AuthType.KAKAO_LOGIN_ALL)
            }

            override fun isUsingWebviewTimer(): Boolean {
                return false
            }

            override fun getApprovalType(): ApprovalType? {
                return ApprovalType.INDIVIDUAL
            }

            override fun isSaveFormData(): Boolean {
                return true
            }

            override fun isSecureMode(): Boolean {
                return true
            }
        }
    }

    override fun getApplicationConfig(): IApplicationConfig {
        return IApplicationConfig {
            GlobalApplication.instance?.getGlobalApplicationContext()
        }
    }
}

 

 

 

 

4. SessionCallback.kt 파일 생성 후 작성

import android.util.Log
import com.kakao.auth.ISessionCallback
import com.kakao.network.ErrorResult
import com.kakao.usermgmt.UserManagement
import com.kakao.usermgmt.callback.MeV2ResponseCallback
import com.kakao.usermgmt.response.MeV2Response
import com.kakao.util.exception.KakaoException

class SessionCallback : ISessionCallback {

    override fun onSessionOpenFailed(exception: KakaoException?) {
        Log.e("Log", "Session Call back :: onSessionOpenFailed: ${exception?.message}")
    }

    override fun onSessionOpened() {
        UserManagement.getInstance().me(object : MeV2ResponseCallback() {

            override fun onFailure(errorResult: ErrorResult?) {
                Log.i("Log", "Session Call back :: on failed ${errorResult?.errorMessage}")
            }

            override fun onSessionClosed(errorResult: ErrorResult?) {
                Log.i("Log", "Session Call back :: onSessionClosed ${errorResult?.errorMessage}")

            }

            override fun onSuccess(result: MeV2Response?) {
                Log.i("Log", "아이디 : ${result!!.id}")
                Log.i("Log", "이메일 : ${result.kakaoAccount.email}")
                Log.i("Log", "프로필 이미지 : ${result.profileImagePath}")

                checkNotNull(result) { "session response null" }
            }

        })
    }
}
