ADB (Android Debug Bridge)

Android 디버그 브리지(adb)는 에뮬레이터 인스턴스나 연결된 Android 기기와 통신할 수 있는 다목적 명령줄 도구.

앱 설치 및 디버깅과 같은 다양한 기기 작업을 쉽게 해주고, 에뮬레이터나 연결된 기기에서 다양한 명령을 실행하는 데 사용할 수 있는 Unix 셸 액세스를 제공


  • - 명령을 전송하는 클라이언트. 클라이언트는 개발용 컴퓨터에서 실행됩니다. adb 명령을 실행하여 명령줄 터미널에서 클라이언트를 호출 
  • - 기기에서 명령을 실행하는 데몬. 데몬은 각 에뮬레이터나 기기 인스턴스에서 백그라운드 프로세스로 실행
  • - 클라이언트와 데몬 간의 통신을 관리하는 서버. 서버는 개발용 컴퓨터에서 백그라운드 프로세스로 실행

ADB로 쉽게 디바이스에 apk 설치 또는 내부 파일에 대해 접근이 가능.

Terminal에서 "ADB"를 치면 사용할 수 있는 여러가지 옵션들이 출력 됨.
