(RCS) Rich communication service DB

Hello,
I develop SMS/MMS viewer application in Korea.
There was no problem to get sms & mms when I use this query.
=> Uri.parse(“content://mms-sms/conversations?simple=true”

But there’s no RCS message when I query using this.
There looks no reference about RCS message .

Can I know or have guide to develop RCS messge ?

한국 개발자입니다. RCS 메시지가 추가되면서 안드로이드 개발시
이 메시지는 기존 방식으로는 보이지 않습니다. RCS관련해서는 갤럭시 개발 가이드를 받을수 있을까요?

Hi,
As far as I know RCS messaging is not still available for 3rd party apps. It should be available from R OS.

Thanks.
