17-1. 맵

※ 맵을 이용하기 위한 설정

 - 구글맵을 이용하기 위해서는 인증을 포함한 몇 가지 설정을 해야 한다.

 - 인증방법

1. Eclipse 실행 -> Widnow메뉴 -> Preferences -> Android -> Build -> SHA1 fingerprint의 값을 구글서버에 등록해야 하므로 복사한다.
2. 구글서버 주소는 http://code.google.com/apis/console 이다.
3. 위의 주소에 접속하여 Google Map Android API 클릭
4. API 키 생성
5. Eclipse로 돌아와 SDK Manager 실행
6. Extras의 Google play service 설치 or 업데이트
7. import -> Android의 Existing Android Code Into Workspace 선택
8. AppData폴더 -> Local -> android-sdk -> extras -> google -> google play service폴더를선택하여 임포트 하기.
9. 적용하려는 프로젝트를 우클릭하여 Properties 를 들어간 후 Android 를 클릭한 후 라이브러리를 추가한다.
10. AndroidMenifest.xml에 등록

<uses-permission android:name="android.permission.INTERNET"/>

<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"/>

<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION"/>

<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"/>

<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>

<uses-permission android:name="com.google.android.providers.gsf.permission.READ_GSERVICES"/>

<permission android:name="패키지명.permission.MAPS_RECEIVE" android:protectionLevel="signature"/>

<meta-data android:name="com.google.android.maps.v2.API_KEY" android:value="Key값"/>

<meta-data android:name="com.google.android.gms.version" android:value="@integer/google_play_services_version"/>
