'c2dm'에 해당되는 글 1건

  1. 2011.09.07 [안드로이드] Push 2 강의 - 2.2 이상 (C2DM 방식)
  
C2DM  방식은 2.2 - sdk 8 이상만 가능합니다. 
2.1 버전 아래는 제가 글 써논 푸시 1강의를 확인해 보시면 될듯 싶습니다.
2.2 버전 C2DM 방식은 자세히 써 내려 가려 합니다.  물론 소스를 완전 오픈할수는 없지만,
사용하시기에 불편함 없을정도일겁니다.

저도 검색을 통해 여러종류의 소스를 얻어 돌려봤는데 이 방법이 저에겐 맞더라구요..

푸시을 위해 아래 주소에 가입을 하고, 해당 주소 메일이 날라옵니다.

2.1 이전과 2.2(C2DM)이상의 버전 으로 if 문을 걸어 놧지요...:)
