이번 프로젝트에서 리액트 네이티브로 모바일을 개발하기로 되었다.
그래서 우선 React Native를 학습하면서 생기는 오류들을 정리하려고 한다.
1. 안드로이드로 실행 시 오류 - 구글 플레이 라이센스 문제

구글 플레이 라이센스 문제로 android studio 에서
Tools < SDK Manager 메뉴로 들어가서
SDK Tools 탭으로 이동하면 중간 쯤에 Google Play Licensing Library 항목이 있다.
이게 인스톨되지 않으면 생기는 오류이다.
해당 항목을 인스톨 하고 재실행하면 된다.

안드로이드 스튜디오 버추얼 디바이스가 실행되지 않아서 생긴문제이다.
안드로이드 스튜디오에서
Tools > AVD Manager 메뉴로 들어가면 Andriod Virtual Device Manager 창이 열리고
여기서 디바이를 더블클릭하여 버츄어 디바이스 실행 후
명령어를 실행하면 정상 작동된다.
