Last active September 21, 2020 16:18
Circular NetworkImageView for use with Volley. Creates a circular bitmap and uses whichever dimension is smaller to determine the radius. Also constrains the circle to the leftmost part of that image. Used in the same way as the Volley NetworkImageView, in both code and xml. Of course you'll need to include the Volley Library in you app too.

Bluetooth API 사용법

Bluetooth 개요

Android Bluetooth를 개발하기전에 Bluetooth 통신에대한 약간의 이해가 필요합니다.
Bluetooth Process를 간단히 설명하자면 주변에 연결하려는 디바이스를 찾고
찾은 기기중 연결할 기기에 인증을 받은 후 그리고 나서 통신을 합니다.

이 내용은 크게 Discovery,Pairing,Connection,Streaming 4가지 STEP으로 나눌수 있습니다.

1.Discovery

주변 디바이스 검색 합니다

  • Discovery는 주변에 블루투스와 연결 가능한 디바이스를 검색하는것 입니다.
