cd <Cocos2d-x 설치 경로>/samples/Cpp/HelloCpp/proj.android

./build_native.sh

이 과정을 통해, 앱 코드와 Cocos2d-x 라이브러리 코드 모두 빌드되며, <Cocos2d-x 설치 경로>/samples/Cpp/HelloCpp/Resouces 밑에 있는 리소스 파일들이 <안드로이드 프로젝트 폴더>/assets로 복사된다.

관련 에러: Cannot run program "bash": Launching failed

※ 빌드 중 "COFF로 변환하는 동안 오류가 발생했습니다" 에러가 발생할 경우, HelloCpp 프로젝트 속성 페이지에 들어가서, 구성 속성 -> 매니페스트 도구 -> 입력 및 출력 밑에 있는 매니페스트 포함 항목을 아니오로 바꾼다.
