Uri.encode() : 파라미터로 한글 등을 보낼 때 URI 형식으로 변환
<String, Integer, Document> : Document doInBackground(String)
1. 첫번째 String : doInBackground()에서 받는 매개변수 타입
2. 두번째 Integer : onProgressUpdate()에서 사용할 변수 타입
3. 세번째 Document : doInBackground()의 리턴 타입
onPreExecute() : 백그라운드 작업을 수행하기 전에 호출
onProgressUpdate() :
1. 백그라운드 작업의 진행 상태를 표시하기 위해 호출
2. 작업 수행 중간 중간에 UI 객체에 접근하는 경우에 사용
3. 작업 중간에 publishProgress()를 호출하면 실행 됨
doInBackground() :
1. 새로 만든 스레드에서 백그라운드 작업을 수행
2. excute(인수1, 인수2,…)의 인수들을 배열로 전달받음
  1. new MyAsyncTask(getContext()).execute(strUrl);
  2. strUrl을 urls[0]로 받음
onPostExecute()
1. 백그라운드 작업이 끝난 후 호출
2. 메인 스레드에서 실행되며 전송받은 내용을 레이아웃에 나타내거나 DB에 저장 등의 작업을 수행
