###################################
1. 이론 및 정보
-----------------------------------
* Activity 실행시 반드시 무언가 실행 시키고 싶으면
LifeCycle에 따라 onResume()
-----------------------------------
앞으로 배울 내용은?
브로드케스트 리시버, Content Provider, xml파싱, db?
브로드케스트 리시버, Content Provider, xml파싱, db?
-----------------------------------
* Main View에 Thread가 접근을 못하게 막아 둠
동기화 문제가 발생하기 때문에
그래서 아래와 같은 해결방법이 있음
핸들러
루퍼
1. handler
2. post - 핸들러를 생략해서 만들 수 있는 거, runnable 상속
3. looper - Run 메서드 안에서만 쓰임, 자식 쓰레드에는 만들어져 있지 않음, Main 쓰레드에는 있음
4. AsyncTask - 복잡한 Thread 코드를 간단하게 구현할 수 있게 해줌, 어려움
-----------------------------------
* Broadcast Receiver
모두에게 전달해주는데 받고 싶은 사람이 받음
이러한 방송 메시지를 직접 만들어서 사용가능
ACTION_XXX 메시지 들이 있음
이런 메시지들이 안드로이드 시스템에서 준비해 놓은 메시지
이런거 말고 직접 만드는게 가능
-----------------------------------
* XML 파싱
주로 SAX를 씀
서버로 부터 필요한 데이터를 받아옴
DOM
SAX
SAX를 좀 더 쉽게
SAX
SAX를 좀 더 쉽게
버스노선 정보 등 LBS
공공기관 API - data.go.kr
-----------------------------------
###################################
2. 설정 및 그 밖에
-----------------------------------
2. 설정 및 그 밖에
-----------------------------------
* 프로젝트 생성 - BroadCastReceiverApp
android.permission.RECEIVE_SMS
-----------------------------------
* Receiver 생성
* Permission 추가
android.permission.RECEIVE_SMS
-----------------------------------
* 에뮬레이터에서 메시지 전송
* 에뮬레이터에서 메시지 전송
