Android Custom ListView 연락처 저장 구현

Android Studio 에서 연락처 저장하는 기능으로 구현에 필요한 내용은 모두 적어둔다.

서버에서 읽어온 사진 이미지까지 저장할 수 있도록 했다.

서버에서 사진 이미지를 읽어오고 나면 Cache에 저장했으므로

MemoryCache memoryCache = new MemoryCache();
Bitmap cachedImage = memoryCache.get(strPhoto);

를 했는데도 불구하고 null 값이 나온다.

연락처(Contacts)에 전화번호를 저장하는 기능은 검사하여 있으면 삭제후 다시 신규 저장하는 방식으로 구현되어 있는데, 이런 로직보다는 데이터가 있으면 비교하여 달라진 것이 있으면 Update 하고 동일하면 패스하는 로직으로 구현하는 것이 바람직하다. 이런 구현방식은 개발자의 몫이기 때문에 여기에는 적어놓지 않는다.
