언리얼에서 배포용으로

안드로이드 빌드를 하는데 아래와 같은 로그를 뻗고 빌드 실패가 나버렸다.

( 제목은 저렇게 붙혔지만 저 에러 로그가 원인이 맞는지는 의문... ㅠ.... )

언리얼은 마지막에 그놈의 Unknown Error 좀 안나왔으면 좋겠다 ㅂㄷㅂㄷ

해결방법은 다음과 같다.

먼저 NVPACK이 설치된 경로(기본 경로 : C:\NVPACK) 에서 \android-sdk-windows\tools 로 접근하면 android.bat이 있다.

andriod.bat을 실행!

실행하면 위와같이 안드로이드 SDK 매니저(Android SDK Manager)가 나온다.

이중에서 Extras/Android Support Repository를 설치하거나 업데이트를 해주면 정상 빌드가 된다.

야호!
