1 스마트폰 HTML5 지원분석 1. 개요 1) 다양한제조사 / 모델및 OS 버전으로부터기인한단말 fragmentation 은안드로이드 Native App 개발 시큰 Risk Factor 가되고있다. ( 출처 : ersion Codename API Distribution 1.6 Donut 4 0.2% 2.1 Éclair 7 2.4% 2.2 Froyo 8 9.0% % Gingerbread % % Honeycomb % Ice Cream Sandwich % % Jelly Bean % Data collected during a 14-day period ending on January 3, ) 적당한 fragmentation 은사용자들에게선택의폭을넓힌다는측면에서긍정적이나, 상기표에서보듯크게중심이되는버전이없으며하드웨어또한다양한해상도와성능의단말이존재한다. 3) 이에따라서비스앱의 time-to-market 과유지보수를위해 native app 과 mobile web 의장점을가진 hybrid 방식의앱이선호되고있다. 4) 하지만 hybrid 앱의내장브라우저또한이러한 fragmentation 에서자유로울수없으며, 따라서본보고서에서는 hybrid 앱개발시 HTML5 적용을위한사전분석으로아래와같은조사를수행하였다. 1 OS 버전 fragmentation 에따른 HTML5 스펙지원확인을위한객관적자료검색 2 단말테스트를통한 HTML5 스펙지원여부확인 3 Animation 이적용된모바일웹화면수행결과 2. 브라우저별 HTML5 지원항목 ( 출처 : Feature Safari on ios Android Browser Google Chrome Platform iphone, ipad Phones & Tablet Android 4.0+ ersions tested 3.2 to to Application Cache 1

Canvas 태그를이용한샘플 : 5

6 2) 단말별체감비교 1 갤럭시S 진저브레드 (2.3.X) 의경우네이티브앱과비교하여애니메이션효과의부드러움과속도가현저히떨어짐. 갤럭시S2 단말의경우도부드럽지는못함. 2 결국, 네이티브앱과비슷한정도의애니메이션을사용한다면속도이슈가있을것으로판단됨. < 참고1. HTML5에대한만족도 > < 참고 2. 모바일브라우저속도 > < 참고 3. 모바일브라우저속도 vs PC 브라우저속도 > 6
