안드로이드 PendingIntent

Notification 메시지를 통해 애플리케이션의 Activity를 실행할 수 있으며 이 때 Pending Intent를 사용한다.
Pending Intent를 통해 실행되는 Activity로 데이터를 전달 할 수 있다.

 

Action

알림 메시지에 Button과 같은 것을 배치하여 이를 눌렀을 때 지정된 Activity를 실행할 수 있다.
안드로이드 4.0 까지는 메시지당 하나의 Activity만 실행이 가능했지만 4.1 이후로 Action이 제공되어 하나의 메시지에서 여러 Activity를 선택적으로 실행할 수 있게 되었다.
