# AndroidManifest.xml 에서 Activity 의 android:screenOrientation=”portrait” 로 지정하더라도 멀티 윈도우에서는 데이터 복원이 필요하다.
그러므로 onSaveInstanceState() 와 onRestoreInstanceState() 를 이용해서 데이터를 복원한다.

# EditText 는 화면이 회전될 때 id 가 지정되어 있다면 데이터가 복원되지만 id 가 지정되어 있지 않다면 데이터가 복원되지 않는다.

 

# 레이아웃 분기 (가로모드용 레이아웃 폴더 만들기)
layout 폴더를 만든다. (Orientation 을 landscape 로 지정)
그리고 activity_main.xml 파일을 layout-land 폴더에 복사한다.
그러면 가로모드일 때는 layout-land 폴더를 타게 된다.

17일차 API Geo IP API

 

1. 구글맵 Activity 를 추가한다.
2. res/values/google_maps.api.xml 파일을 연다.
3. 링크를 따라가서 api 키를 받아서 붙여넣기 한다.
4. 핵심 코드들을 내 activity 에 붙여넣기 한다.
