2 AppName Oh! My Taxi 택시요금예상측정기 목차 개발동기 본 App의차별성 기능구상 개발과정 동작원리및사용방법 사용도구및 Open Sources(API, Lib) 결과물및추후개발방향 소스코드세부사항 개발동기 이동수단으로택시를선택할때택시비에대한것이늘고민되고걱정된다. 타지에서방문한초행자이거나, 외국인, 버스운행시간종료시에효율적으로택시비를예상하여자금상황과견주어볼어플리케이션의필요성을느껴개발하게되었다. 번거로움없이지정된위치와현재위치간의계산을위하여각기능을추가하여개발하였다 타 App 과비교 < App > < Call Taxi App > 예 1 : 이동경로나미터기에대해 GPS 를이용하여추적하는 App 예 2 : 택시회사에서콜택시에대한서비스를제공하는 App 본 App 가원하는기능의응용은찾아보기힘들다.

3 기능구상 ( 제안내용 ) 및개발환경 기능구상 - 지도탑재 - 선택한위치간의최단경로구현 - 경로의거리측정 - 측정된거리를바탕으로요금계산 - 도착지정보를즐겨찾기로등록 - 즐겨찾기정보를이용하여현재위치를읽어동작 개발환경 - 운영체제 : Windows XP Pro sp3 x86(32bit) Android Icecream Sandwitch (AVD) 개발과정 개괄 - MapView를구현한다음위치를선택하여경로및거리를찾아내어택시요금을계산한다. - 도착지정보를즐겨찾기하여해당위치를출발 / 도착로세팅후현재위치를읽어서위치를선택한다. 단계별세부사항

4 동작원리및사용방법 동작원리 - 앱이시작되면 Map으로의전환과, 즐겨찾기 (DB) 된 ListView가출력된다. - MapView는 DaumOpenAPI를사용하여띄운다. - DaumMaps의메소드를통해위치정보를출발 / 도착지로설정하고해당정보를 ArrayList 로저장한다. - 각각 [0],[1] Node가출발 / 도착지로, 해당정보를가지고 DaumMap의길찾기항목의경로로전송하여 json 파일을받는다. - json파일을파싱하여 NODE별위치를얻어서 HashMap으로받아온다. - HashMap의내용을 Map에 Point를찍어 PolyLine을구현한다. - 도착지의정보 ( 좌표 ) 는 db에추가하여파일로저장한다. - db( 좌표 ) 를읽어와서도착 / 출발지로설정하고, 현위치를호출하여요금계산을수행한다. 사용방법 - 앱을실행시키면버튼과즐겨찾기가있는메인화면이보인다. < > - 위치지정버튼을누르면 MapView가있는화면으로전환된다. 원하는위치로 Map을이동시킨후길게누르면첫번째터치가출발지로, 두번째터치가도착지로지정된다. 기기에있는 Menu을눌러서도착지정보를즐겨찾기로추가할수있다. < MapView, > < >

5 - 요금계산버튼을누르면요금계산화면으로전환된다. 해당좌표값과거리가뜨는데, 상단의요금계산버튼을누르면일반택시 ( 할증 ) 모범택시의예상요금을알수있다. 위치확인버튼을누르면이전경로가표시된화면으로전환되고다시보기버튼을누르면경로가사라진화면으로전환된다. < > - 즐겨찾기추가후처음화면으로돌아가면리스트의형태로위치정보가표시됨을알수있다 출발지그림을누르면해당정보가출발지로, 도착지그림을누르면해당정보가도착지로 설정되고, 현재위치와의길찾기부터수행한다. < ListView, main > < >

6 사용도구및 OpenSources(API, Lib) Mobile DaumMap Open API - Daum에서제공하는 Android용모바일맵오픈 API - MapView, MapPoint, MapPointItem 등의메소드를지원한다. DaumMap Local API - Daum에서제공하는웹용오픈 API(java) - Mobile에서지원하지않는길찾기나좌표계변환기능을지원하고, 본 App에서해당기능을웹에서 Json 파일로받아오는데사용하였다. TransCoord Class - Daum 로컬 API의좌표계변환부분을 Android 용 Class로포팅한것. - Local API 의 Key( 권한 ) 없이사용할수있다. LocationManager - 위치정보를위해 Google에서제공하는 API로 Provider (Network, GPS) 를이용하여받아오는데이용하였다. - 본 App에서는 Network Provider을이용하여기지국정보로부터위치를받아와서사용했다. 결과물및추후개발방향 구현한기능 - 지정된위치에따른경로 ( 길찾기 ) 표시 - db를이용한즐겨찾기항목저장및리스트뷰를이용한즐겨찾기출력 - 네트워크프로바이더를이용한현위치트래킹 - 거리에따른택시요금계산 - 위치에따른경로표시 - 좌표계변환 미구현된기능 - (Reverse) Geo-coding( 주소 좌표 ) 를이용한위치표현 - 시간에따른택시과금적용 개발방향 - Mobile DaumMap API가길찾기기능을제공하지않으므로해당기능들을완전 open source 인 GoogleMaps로포팅 - 미구현기능의추가및예외처리향상 - UI 디자인강화, 도움말항목추가
