Navigation SDK는 현재 일부 고객만 사용할 수 있습니다. 자세한 내용은 영업팀에 문의하세요.
새로운 지도 스타일 지정 기능이 곧 Google Maps Platform에 도입될 예정입니다. 이번 지도 스타일 지정 업데이트에는 새로운 기본 색상 팔레트가 추가되었으며 지도 환경 및 사용성이 개선되었습니다. 모든 지도 스타일은 2025년 3월에 자동으로 업데이트됩니다. 사용 가능 여부 및 이전에 선택한 방법에 대한 자세한 내용은 Google Maps Platform의 새 지도 스타일을 참고하세요.
getSimulator()를 사용하여 경로를 따라 차량의 진행률을 시뮬레이션하고 앱을 테스트, 디버깅 및 시연합니다.
앱을 빌드하고 실행합니다.

탐색 프래그먼트 추가
SupportNavigationFragment은 대화형 지도와 세부 경로 안내를 비롯하여 탐색의 시각적 출력을 표시하는 UI 구성요소입니다. 아래와 같이 XML 레이아웃 파일에서 프래그먼트를 선언할 수 있습니다.
앱에서 런타임 권한을 요청하여 사용자에게 위치 정보 액세스 권한을 허용 또는 거부할 수 있는 기회를 제공합니다. 다음 코드는 사용자가 상세한 위치 정보 액세스 권한을
부여했는지 확인합니다. 부여하지 않은 경우, 해당 권한을 요청합니다.
if(ContextCompat.checkSelfPermission(this.getApplicationContext(),android.Manifest.permission.ACCESS_FINE_LOCATION)==PackageManager.PERMISSION_GRANTED){mLocationPermissionGranted=true;}else{ActivityCompat.requestPermissions(this,newString[]{android.Manifest.permission.ACCESS_FINE_LOCATION},PERMISSIONS_REQUEST_ACCESS_FINE_LOCATION);}if(!mLocationPermissionGranted){displayMessage("Error loading Navigation SDK: "+"The user has not granted location permission.",DISPLAY_BOTH);return;}
권한 요청의 결과를 처리하도록 onRequestPermissionsResult() 콜백을 재정의합니다.

이 여정의 모든 경유지를 설정합니다. (탐색기에서 경로를 표시할 수 없는 장소 ID를 사용하면 오류가 발생할 수 있습니다. 이 가이드의 샘플 앱에서는 오스트레일리아의 경유지에 장소 ID를 사용합니다. 다른 장소 ID 가져오기에 관한 아래의 메모를 참고하세요.) 경로를 계산한 후 SupportNavigationFragment는 각 경유지에 마커와 함께 경로를 나타내는 다중선을 지도에 표시합니다.

앱 빌드 및 실행
컴퓨터에 Android 기기를 연결합니다. 안내에 따라
Android 기기에서 개발자 옵션을 사용 설정하고
기기를 감지하도록 시스템을 구성합니다. (또는
Android Virtual Device(AVD) Manager를
사용하여
가상 기기를 구성할 수 있습니다. 에뮬레이터를 선택할 때 Google API가 포함된 이미지를 선택해야 합니다.)
Android 스튜디오에서 Run 메뉴 옵션(또는 재생 버튼 아이콘)을 클릭합니다.
표시되는 메시지에 따라 기기를 선택합니다.
사용자 환경 개선을 위한 팁
사용자가 Google 내비게이션 서비스 약관에 동의해야 내비게이션을 사용할 수 있습니다. 동의는 한 번만 하면 됩니다. 기본적으로 SDK는 탐색기를 처음 호출할 때 수락 여부를 묻는 메시지를 표시합니다. 원하는 경우 showTermsAndConditionsDialog()를 사용하여 가입 또는 로그인 중에 앱의 UX 흐름 초기에 내비게이션 서비스 약관 대화상자를 트리거할 수 있습니다.
도착지 경도/위도 대신 장소 ID를 사용하여 중간 지점을 초기화하면 내비게이션 품질과 도착 예정 시간 정확성이 크게 개선됩니다.
이 샘플은 특정 장소 ID에서 웨이포인트를 가져옵니다. 장소 ID를 가져오는 다른 방법은 다음과 같습니다.
