Follow this guide to plot a route within your app to multiple destinations,
also called waypoints, using the Navigation SDK for Android. You can set a
maximum of 25 waypoints, including the final destination.

## Overview

1. Integrate the Navigation SDK into your app, as described in [Set up your project](https://developers.google.com/maps/documentation/navigation/android-sdk/set-up-project).
2. Add a [`NavigationFragment`](https://developers.google.com/maps/documentation/navigation/android-sdk/reference/com/google/android/libraries/navigation/NavigationFragment) or [`NavigationView`](https://developers.google.com/maps/documentation/navigation/android-sdk/reference/com/google/android/libraries/navigation/NavigationView) to your app. This UI element adds the interactive map and turn-by-turn navigation UI to your activity.
3. Use the [`NavigationApi`](https://developers.google.com/maps/documentation/navigation/android-sdk/reference/com/google/android/libraries/navigation/NavigationApi) class to initialize the SDK.
4. Define a [`Navigator`](https://developers.google.com/maps/documentation/navigation/android-sdk/reference/com/google/android/libraries/navigation/Navigator) to control turn-by-turn navigation:

   - Add destinations using [`setDestinations`](https://developers.google.com/maps/documentation/navigation/android-sdk/reference/com/google/android/libraries/navigation/Navigator#setDestinations(java.util.List%3Ccom.google.android.libraries.navigation.Waypoint%3E)).
   - Start navigation with [`startGuidance`](https://developers.google.com/maps/documentation/navigation/android-sdk/reference/com/google/android/libraries/navigation/Navigator#startGuidance()).
   - Use [`getSimulator`](https://developers.google.com/maps/documentation/navigation/android-sdk/reference/com/google/android/libraries/navigation/Navigator#getSimulator()) to simulate the progress of the vehicle along the route, for testing, debugging, and demonstrating your app.
5. Build and run your app.

## Add a navigation fragment

The [`NavigationFragment`](https://developers.google.com/maps/documentation/navigation/android-sdk/reference/com/google/android/libraries/navigation/NavigationFragment) is the UI component
that displays the visual output of navigation, including an interactive map and
turn-by-turn directions. You can declare the fragment in your XML layout file as
follows:

    <?xml version="1.0" encoding="utf-8"?>
    <fragment xmlns:android="http://schemas.android.com/apk/res/android"
        android:name="com.google.android.libraries.navigation.NavigationFragment"
        android:id="@+id/navigation_fragment"
        android:layout_width="match_parent"
        android:layout_height="match_parent"/>

Alternatively, you can construct the fragment programmatically, as described in
the [Android documentation](https://developer.android.com/training/basics/fragments/creating.html), using
[`FragmentActivity.getSupportFragmentManager()`](https://developer.android.com/reference/android/support/v4/app/FragmentActivity.html#getSupportFragmentManager()).

> [!NOTE]
> **Note:** `SupportNavigationFragment` is deprecated in Navigation SDK v8.0.0. If you're updating existing code, see [Update to NavigationFragment](https://developers.google.com/maps/documentation/navigation/android-sdk/nav-map-interactions-best-practices#update-to-navigation-fragment).

As an alternative to a fragment, the UI component is also available as a
[`NavigationView`](https://developers.google.com/maps/documentation/navigation/android-sdk/reference/com/google/android/libraries/navigation/NavigationView). In most cases, we recommend using
[`NavigationFragment`](https://developers.google.com/maps/documentation/navigation/android-sdk/reference/com/google/android/libraries/navigation/NavigationFragment),
which is a wrapper for
[`NavigationView`](https://developers.google.com/maps/documentation/navigation/android-sdk/reference/com/google/android/libraries/navigation/NavigationView),
instead of interacting directly with `NavigationView`. For more information, see
[Navigation map interaction best practices](https://developers.google.com/maps/documentation/navigation/android-sdk/nav-map-interactions-best-practices).

## Request location permission

Your app must request location permission in order to determine the
location of the device.

This tutorial provides the code you need to request fine location permission.
For more details, see the guide to [Android permissions](https://developer.android.com/training/permissions/requesting.html).

1. Add the permission as a child of the `<manifest>` element in your Android
   manifest:

           <manifest xmlns:android="http://schemas.android.com/apk/res/android"
               package="com.example.navsdkmultidestination">
               <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
           </manifest>

2. Request runtime permissions in your app, giving the user the opportunity
   to allow or deny location permission. The following code checks whether the
   user has granted fine location permission. If not, it requests the permission:

           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;
           }

3. Override the `onRequestPermissionsResult` callback to handle the result of
   the permission request:

           @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;
                       }
                   }
               }
           }

## Initialize the Navigation SDK and configure a journey

The [`NavigationApi`](https://developers.google.com/maps/documentation/navigation/android-sdk/reference/com/google/android/libraries/navigation/NavigationApi) class provides initialization logic
that authorizes your app to use Google navigation. The [`Navigator`](https://developers.google.com/maps/documentation/navigation/android-sdk/reference/com/google/android/libraries/navigation/Navigator)
class provides control over configuring, starting, and stopping a navigation
journey.

1. Create a helper method to show a message on screen and in the log.

           private void displayMessage(String errorMessage, String displayMedium) {
               if (displayMedium.equals(DISPLAY_BOTH) || displayMedium.equals(DISPLAY_TOAST)) {
                   Toast.makeText(this, errorMessage, Toast.LENGTH_LONG).show();
               }

               if (displayMedium.equals(DISPLAY_BOTH) || displayMedium.equals(DISPLAY_LOG)) {
                   Log.d(TAG, errorMessage);
               }
           }

2. Initialize the Navigation SDK and override the
   `onNavigatorReady` callback to start navigation when the navigator is
   ready:

           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 = (NavigationFragment) getSupportFragmentManager()
                                   .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);
                           }
                       }
                   });

3. Add a method to create a [`Waypoint`](https://developers.google.com/maps/documentation/navigation/android-sdk/reference/com/google/android/libraries/navigation/Waypoint) object from a given place
   ID and title.

           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);
               }
           }

4. Add a method to display the calculated travel time and distance to each
   waypoint.

           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);
           }

5. Set up to 25 waypoints for this journey. After calculating directions, the
   [`NavigationFragment`](https://developers.google.com/maps/documentation/navigation/android-sdk/reference/com/google/android/libraries/navigation/NavigationFragment) displays a
   polyline representing the route on the map, with a marker at each
   waypoint.

   > [!NOTE]
   > **Note:** You might receive an error if you use place IDs for which the navigator can't plot a route. The sample app in this tutorial uses place IDs for waypoints in Australia. See how to [get different place
   > IDs](https://developers.google.com/maps/documentation/navigation/android-sdk/multi-destination#get-place-id).

           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)
                       && mSavedInstanceState.getInt(KEY_JOURNEY_IN_PROGRESS) == 1) {
                   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.
               pendingRoute.setOnResultListener(
                       new ListenableResultFuture.OnResultListener<Navigator.RouteStatus>() {
                           @Override
                           public void onResult(Navigator.RouteStatus code) {
                               switch (code) {
                                   case OK:
                                       mJourneyInProgress = true;
                                       // Hide the toolbar to maximize the navigation UI.
                                       if (getActionBar() != null) {
                                           getActionBar().hide();
                                       }

                                       // Register some listeners for navigation events.
                                       registerNavigationListeners();

                                       // Display the time and distance to each waypoint.
                                       displayTimesAndDistances();

                                       // Enable voice audio guidance (through the device speaker).
                                       AudioGuidanceSettings audioSettings =
                                               AudioGuidanceSettings.builder()
                                                       .setGuidanceMode(
                                                               AudioGuidanceSettings.GuidanceMode
                                                                       .VOICE_ALERTS_AND_GUIDANCE)
                                                       .build();
                                       mNavigator.setAudioGuidanceSettings(audioSettings);

                                       // Simulate vehicle progress along the route for demo/debug builds.
                                       if (BuildConfig.DEBUG) {
                                           mNavigator.getSimulator().simulateLocationsAlongExistingRoute(
                                                   new SimulationOptions().speedMultiplier(5));
                                       }

                                       // Start turn-by-turn guidance along the current route.
                                       mNavigator.startGuidance();

                                       displayMessage("Error starting navigation: "
                                               + String.valueOf(code), DISPLAY_BOTH);
                               }
                           }
                       });
           }

## Build and run your app

1. Connect an Android device to your computer. Follow the [instructions](https://developer.android.com/studio/run/device.html) to enable developer options on your Android device and configure your system to detect the device. (Alternatively, you can use the [Android Virtual Device (AVD) Manager](https://developer.android.com/studio/run/managing-avds.html) to configure a virtual device. When choosing an emulator, make sure you pick an image that includes the Google APIs.)
2. In Android Studio, click the **Run** menu option (or the play button icon). Choose a device as prompted.

## Hints for improved user experience

- The user must accept the Google Navigation Terms of Service before navigation becomes available. This acceptance is only required once. By default, the SDK prompts for acceptance the first time the navigator is invoked. If you prefer, you can trigger the Navigation Terms of Service dialog at an early point in your app's UX flow, such as during signup or login, using [`showTermsAndConditionsDialog`](https://developers.google.com/maps/documentation/navigation/android-sdk/reference/com/google/android/libraries/navigation/NavigationApi#showTermsAndConditionsDialog(android.app.Activity,%20com.google.android.libraries.navigation.NavigationApi.OnTermsResponseListener)).
- Navigation quality and ETA accuracy are significantly improved if you use place IDs to initialize a waypoint, rather than a latitude/longitude destination.
- This sample derives the waypoints from specific place
  IDs. Other ways to get a place ID include the following:

- Use the [place ID finder](https://developers.google.com/maps/documentation/places/web-service/place-id) to get place IDs for specific
  locations.

- Use the [Geocoding API](https://developers.google.com/maps/documentation/geocoding) to find the place ID
  for a given address. The Geocoding API works well if you have
  complete, unambiguous addresses for the waypoints. See the [geocoding best
  practices guide](https://developers.google.com/maps/documentation/geocoding/best-practices).

- Use the [Places API text search](https://developers.google.com/maps/documentation/places/web-service/search#TextSearchRequests) to find the place
  ID for a given address. The Places API works well if you have
  incomplete or ambiguous addresses for the waypoints. See the [geocoding best
  practices guide](https://developers.google.com/maps/documentation/geocoding/best-practices).
