open-source CodePath Android Cliffnotes에 오신 것을 환영합니다! 이 프로젝트의 목적은 완성도 높고, 최신의 내용을 담은 안드로이드 개발자를 위한 예제를 담은 주제를 가지고 크라우드소싱 방식으로 자료를 제공하는 것이 목표입니다. 본문으로 바로가기!
우리는 당신이 초보자이던, 중급자이던 혹은 숙련자이건 상관없이 모두에게 도움이되는 안드로이드 개발 가이드를 제공합니다.
ActionBar를 사용하는법 혹은 Fragment를 다루는법에 대하여 궁금하신가요? 이러한 내용은 당연히 제공합니다.
혹시 테스트를 자동화하는 작업이나 다양한 디바이스를 지원하는 유연한 유저 인터페이스를 만드는법에 대해서도 궁금하신가요? 우리는 그런 수준에 대해서도 자료를 제공합니다.
우리는 책으로부터 얻게되는 "이론적인 접근법"에 대해서 여러분들이 시간을 낭비하게 하지않습니다.
우리는 우리가 앱을 개발하면서 직면하는 우리가 자주 다뤄야하는 것들에 대해서 다룹니다.
도움이 필요하신가요? gitter 실시간 채팅 이나 구글 그룹스에 가입하세요, 그곳에서는 여러분들이 이 가이드와 관련하여 관련있는 질문들을 게시 할 수 있습니다. 여러분들은 또한 1:1 온라인 멘토링을 통해서 코딩 멘토를 구할수도 있습니다.
Ever been frustrated finding information on outdated one-off blog posts and tutorials that have long since become irrelevant? How many times have you been googling to find your answer only exists on an obscure 2 year old StackOverflow post? We believe there's got to be a better way. Why not have the community work together to create useful and detailed documentation for every aspect of Android (or any platform)? There's absolutely no reason that we should have to make do with vague and outdated content anymore.
Read about our mission to change the way engineers learn new technologies and check out how you can get involved! In addition, we are at present a fledgling startup so if you like this guide and what we are trying to do, please consider following us on twitter @codepath!
The cliffnotes below are categorized by their topic, so you can easily find guides on related topics whether that is views, styling, testing, or using sensors. If you see an error, incorrect explanation or deprecated solution, why not contribute back and make these cliffnotes better for the next person? That in a nutshell is the core spirit of this initiative. Check out the list of contributors to this project.
Disclaimer: We have scoured the web endlessly for content while creating these guides and adapted content from many source including the Google Official Docs, Vogella Tutorials and countless other sources that had hidden gems of information. At the bottom of each guide, there are citations for the content we used. We don't claim the content is original (although we did develop quite a bit ourselves), but unlike those other sources listed, it is freely community editable. We have openly adapted, modified and brought together this content from all the sources we could find for the benefit of every engineer.
