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 진행 상황을 시뮬레이션하여 앱을 테스트, 디버그, 데모합니다.
앱을 빌드하고 실행합니다.

탐색 프래그먼트 추가
SupportNavigationFragment는 대화형 지도 및 세부 경로 안내를 비롯한 내비게이션의 시각적 출력을 표시하는 UI 구성요소입니다. 다음과 같이 XML 레이아웃 파일에서 프래그먼트를 선언할 수 있습니다.
앱에서 런타임 권한을 요청하여 사용자에게 위치 정보 액세스 권한을 허용하거나 거부할 기회를 제공합니다. 다음 코드는 사용자가 세밀한 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;}
onRequestPermissionsResult() 콜백을 재정의하여 권한 요청의 결과를 처리합니다.

이 경로의 모든 중간 지점을 설정합니다. 내비게이터에서 경로를 표시할 수 없는 장소 ID를 사용하면 오류가 발생할 수 있습니다. 이 튜토리얼의 샘플 앱은 오스트레일리아의 중간 지점에 장소 ID를 사용합니다. 아래의 다른 장소 ID 가져오기에 관한 메모를 참고하세요.) 경로를 계산한 후 SupportNavigationFragment는 지도에 경로를 나타내는 다중선과 각 중간 지점에 마커를 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 때는 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 힌트
탐색을 사용하려면 사용자가 Google 탐색 서비스 약관에 동의해야 합니다. 이 수락은 한 번만 하면 됩니다. 기본적으로 SDK는 탐색기가 처음 호출될 때 동의 메시지를 표시합니다. 원하는 경우 showTermsAndConditionsDialog()를 사용하여 가입 또는 로그인 중에 앱의 UX 흐름 초기에 탐색 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 중간 지점을 가져옵니다. 장소 ID를 가져오는 다른 방법은 다음과 같습니다.
