안드로이드 만보기 소스

안녕하세요~ 이번에 안드로이드에 대해 독학으로 공부하고 있는 학생입니다.

 

기본 지식이 많이 없는 편이라 이렇게 질문을 올리게 되었습니다.

 

귀찮더라두 끝까지 봐주시고 저에게 좋은 스승이 되어주세요

 

질문은 가속도 센서를 이용해서 만보기를 만들어 볼라고 하는데요

 

여차여차 소스를 구하게 되었습니다. 그래서 이것을 토대로 공부를 하고 싶어하는데요

 

소스들이 무엇을 의미하는지 몰라서 이렇게 질문을 하게 되었습니다 스승님들 저에게 가르침을 주세요~

 

자세한 설명 부탁드리겠습니다!! (__)꾸벅!
