I/SearchActivity: Progress change observed

• AuthLoginListener의 onEvent() 메소드에 의해 Observe 실행

I/AuthRepo: Finishing code exchange

• onTokenRequestCompleted() > finishCodeExchange() 메소드 실행됨
• loginListener.onEvent(AuthRepo.this, AUTH_CODE_EXCHANGE_FINISH) 실행됨

I/SearchViewModel: Code exchange finished

• loginListener.onEvent(AuthRepo.this, AUTH_CODE_EXCHANGE_FINISH) 실행
