Navigation SDK saat ini hanya tersedia untuk pelanggan tertentu. Hubungi bagian penjualan untuk mempelajari lebih lanjut.
Gaya visual peta baru akan segera hadir di Google Maps Platform. Perubahan pada gaya visual peta ini mencakup palet warna default baru serta peningkatan pada pengalaman dan kegunaan peta. Semua gaya peta akan otomatis diperbarui pada Maret 2025. Untuk informasi lebih lanjut tentang ketersediaan dan cara memilih untuk ikut serta lebih awal, lihat Gaya peta baru untuk Google Maps Platform.
Ikuti panduan ini untuk memetakan rute dalam aplikasi Anda ke beberapa tujuan,
yang juga disebut titik jalan, menggunakan Navigation SDK for Android.
Ringkasan
Integrasikan Navigation SDK ke dalam aplikasi Anda, sebagai
yang dijelaskan dalam Menyiapkan project Anda.
Tambahkan SupportNavigationFragment atau
NavigationView ke aplikasi Anda. Elemen UI ini
menambahkan peta interaktif dan UI navigasi belokan demi belokan ke aktivitas Anda.
Gunakan class NavigationApi untuk menginisialisasi SDK.
Tentukan Navigator untuk mengontrol navigasi belokan demi belokan:
Gunakan getSimulator() untuk menyimulasikan progres
kendaraan di sepanjang rute, untuk pengujian, proses debug, dan mendemonstrasikan
.
Build dan jalankan aplikasi Anda.

Menambahkan fragmen navigasi
SupportNavigationFragment adalah komponen UI yang menampilkan
output visual navigasi, termasuk peta interaktif dan rute
per belokan. Anda dapat mendeklarasikan fragmen dalam file tata letak XML seperti yang ditunjukkan di bawah:
Aplikasi Anda harus meminta izin akses lokasi untuk menentukan
lokasi perangkat.
Tutorial ini menyediakan kode yang Anda butuhkan untuk meminta izin akses lokasi yang sangat akurat.
Untuk mengetahui detail selengkapnya, lihat panduan izin Android.
Tambahkan izin sebagai turunan elemen <manifest> di Android Anda
manifest:
Meminta izin runtime dalam aplikasi Anda, yang akan memberikan kesempatan kepada pengguna
untuk mengizinkan atau menolak
izin akses lokasi. Kode berikut memeriksa apakah
pengguna telah memberikan izin akses lokasi akurat. Jika tidak, kode ini akan meminta izin tersebut:
if (ContextCompat.checkSelfPermission(this.getApplicationContext(),
android.Manifest.permission.ACCESS_FINE_LOCATION)
== PackageManager.PERMISSION_GRANTED) {
mLocationPermissionGranted = true;
} else {
ActivityCompat.requestPermissions(this,
new String[] { 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;
}
Ganti callback onRequestPermissionsResult() untuk menangani hasil
permintaan izin akses:
@Override
public void onRequestPermissionsResult(int requestCode, @NonNull String permissions[],
@NonNull int[] grantResults) {
mLocationPermissionGranted = false;
switch (requestCode) {
case PERMISSIONS_REQUEST_ACCESS_FINE_LOCATION: {
// If request is canceled, the result arrays are empty.
if (grantResults.length > 0
&& grantResults[0] == PackageManager.PERMISSION_GRANTED) {
mLocationPermissionGranted = true;
}
}
}
}
Melakukan inisialisasi Navigation SDK dan mengonfigurasi perjalanan
Class NavigationApi menyediakan logika inisialisasi
yang mengizinkan aplikasi Anda untuk menggunakan navigasi Google. Navigator
memberikan kontrol untuk mengonfigurasi dan memulai/menghentikan navigasi
perjalanan Anda.
Buat metode bantuan untuk menampilkan pesan di layar dan di log.
Lakukan inisialisasi Navigation SDK dan ganti
callback onNavigatorReady() untuk memulai navigasi saat navigator
siap:
NavigationApi.getNavigator(this, new NavigationApi.NavigatorListener() {
/**
* Sets up the navigation UI when the navigator is ready for use.
*/
@Override
public void onNavigatorReady(Navigator navigator) {
displayMessage("Navigator ready.", DISPLAY_BOTH);
mNavigator = navigator;
mNavFragment = (SupportNavigationFragment) getFragmentManager()
.findFragmentById(R.id.navigation_fragment);
// Set the camera to follow the device location with 'TILTED' driving view.
mNavFragment.getCamera().followMyLocation(Camera.Perspective.TILTED);
// Navigate to the specified places.
navigateToPlaces();
}
/**
* Handles errors from the Navigation SDK.
* @param errorCode The error code returned by the navigator.
*/
@Override
public void onError(@NavigationApi.ErrorCode int errorCode) {
switch (errorCode) {
case NavigationApi.ErrorCode.NOT_AUTHORIZED:
displayMessage("Error loading Navigation SDK: Your API key is "
+ "invalid or not authorized to use the Navigation SDK.",
DISPLAY_BOTH);
break;
case NavigationApi.ErrorCode.TERMS_NOT_ACCEPTED:
displayMessage("Error loading Navigation SDK: User did not accept "
+ "the Navigation Terms of Use.", DISPLAY_BOTH);
break;
case NavigationApi.ErrorCode.NETWORK_ERROR:
displayMessage("Error loading Navigation SDK: Network error.",
DISPLAY_BOTH);
break;
case NavigationApi.ErrorCode.LOCATION_PERMISSION_MISSING:
displayMessage("Error loading Navigation SDK: Location permission "
+ "is missing.", DISPLAY_BOTH);
break;
default:
displayMessage("Error loading Navigation SDK: " + errorCode,
DISPLAY_BOTH);
}
}
});
Tambahkan metode untuk membuat objek Waypoint dari tempat tertentu
ID dan judul.
private void createWaypoint(String placeId, String title) {
try {
mWaypoints.add(
Waypoint.builder()
.setPlaceIdString(placeId)
.setTitle(title)
.build()
);
} catch (Waypoint.UnsupportedPlaceIdException e) {
displayMessage("Error starting navigation: Place ID is not supported: " + placeId,
DISPLAY_BOTH);
}
}
Tambahkan metode untuk menampilkan waktu perjalanan dan jarak yang dihitung ke masing-masing
titik jalan.
private void displayTimesAndDistances() {
List<TimeAndDistance> timesAndDistances = mNavigator.getTimeAndDistanceList();
int leg = 1;
String message = "You're on your way!";
for (TimeAndDistance timeAndDistance : timesAndDistances) {
message = message + "\nRoute leg: " + leg++
+ ": Travel time (seconds): " + timeAndDistance.getSeconds()
+ ". Distance (meters): " + timeAndDistance.getMeters();
}
displayMessage(message, DISPLAY_BOTH);
}
Tetapkan semua titik jalan untuk perjalanan ini. (Perhatikan bahwa Anda mungkin menerima error
jika menggunakan ID tempat yang rutenya tidak dapat dipetakan oleh navigator. Sampel
aplikasi dalam tutorial ini menggunakan ID tempat untuk titik jalan di Australia. Lihat catatan
di bawah tentang mendapatkan ID tempat yang berbeda.) Setelah menghitung
rute, SupportNavigationFragment menampilkan polyline
yang menampilkan rute pada peta, dengan penanda di setiap titik jalan.
private void navigateToPlaces() {
// Set up a waypoint for each place that we want to go to.
createWaypoint("ChIJq6qq6jauEmsRJAf7FjrKnXI", "Sydney Star");
createWaypoint("ChIJ3S-JXmauEmsRUcIaWtf4MzE", "Sydney Opera House");
createWaypoint("ChIJLwgLFGmuEmsRzpDhHQuyyoU", "Sydney Conservatorium of Music");
// If this journey is already in progress, no need to restart navigation.
// This can happen when the user rotates the device, or sends the app to the background.
if (mSavedInstanceState != null
&& mSavedInstanceState.containsKey(KEY_JOURNEY_IN_PROGRESS)

return;
}
// Create a future to await the result of the asynchronous navigator task.
ListenableResultFuture<Navigator.RouteStatus> pendingRoute =
mNavigator.setDestinations(mWaypoints);
// Define the action to perform when the SDK has determined the route.

Membuat dan menjalankan aplikasi
Hubungkan perangkat Android ke komputer Anda. Ikuti petunjuk untuk mengaktifkan opsi developer di perangkat Android Anda dan mengonfigurasi sistem untuk mendeteksi perangkat tersebut. (Atau, Anda dapat menggunakan Android Virtual Device (AVD) Manager untuk mengonfigurasi perangkat virtual. Saat memilih emulator, pastikan Anda memilih image yang berisi
Google API.)
Di Android Studio, klik opsi menu Run (atau ikon tombol putar).
Pilih perangkat saat diminta.
Petunjuk untuk meningkatkan pengalaman pengguna
Pengguna harus menyetujui Persyaratan Layanan Navigasi Google sebelum
navigasi tersedia. Persetujuan ini hanya diperlukan satu kali. Secara default, SDK meminta persetujuan saat navigator pertama kali dipanggil. Jika mau, Anda dapat memicu dialog Persyaratan Layanan Navigasi
titik awal dalam alur UX aplikasi Anda, seperti saat mendaftar atau login, menggunakan
showTermsAndConditionsDialog()
Kualitas navigasi dan akurasi ETA akan meningkat secara signifikan jika Anda menggunakan
ID tempat untuk melakukan inisialisasi titik jalan, bukan tujuan lintang/bujur.
Contoh ini mendapatkan titik jalan dari tempat tertentu
pelanggan. Cara lain untuk mendapatkan ID tempat meliputi:
Gunakan pencari ID tempat untuk mendapatkan ID tempat untuk
lokasi HTTP/HTTPS.
Gunakan Geocoding API untuk menemukan ID tempat
untuk alamat tertentu. Geocoding API berfungsi dengan baik jika Anda memiliki alamat yang lengkap dan tidak ambigu untuk titik jalan. Lihat
panduan praktik terbaik geocoding.
Gunakan penelusuran teks Places API untuk menemukan
ID tempat untuk alamat yang diberikan. Places API berfungsi dengan baik jika Anda
memiliki alamat yang tidak lengkap atau ambigu untuk titik jalan. Lihat
panduan praktik terbaik geocoding.
