How to Display Track on Google Map on Android Studio?

In this tutorial, we will learn how to display a track on Google Map in Android Studio. Displaying tracks on a map can be useful in various applications, such as fitness tracking apps, navigation apps, or tracking the movement of objects. By following the steps below, you’ll be able to integrate Google Maps into your Android app and show a track on the map.

Step 1: Create a new project in Android Studio, or open an existing project.

Step 2: Add the Google Play Services library to your project by adding the following dependency to your app-level build.gradle file:

implementation 'com.google.android.gms:play-services-maps:17.0.0'

Step 3: Generate a Google Maps API key by following the instructions provided by the Google Maps Platform documentation. This API key will allow your app to access and use Google Maps services.

Step 4: In your app’s manifest file, add the following permissions:

Step 5: Add a MapView element to your XML layout file. This element will display the Google Map. Make sure to set the API key attribute to the generated Google Maps API key.

Step 6: In your activity or fragment class, initialize the MapView and obtain a reference to the GoogleMap object.


MapView mapView = findViewById(R.id.mapView);
mapView.onCreate(savedInstanceState);
GoogleMap googleMap = mapView.getMap();


Step 7: Utilize the GoogleMap object to display the track on the map. You can do this by adding markers and polylines to the map. Markers represent specific points on the track, while polylines connect these points to form a continuous line.


// Add markers
googleMap.addMarker(new MarkerOptions().position(new LatLng(latitude1, longitude1)).title("Start Point"));
googleMap.addMarker(new MarkerOptions().position(new LatLng(latitude2, longitude2)).title("End Point"));

// Add polyline
List points = new ArrayList<>();
points.add(new LatLng(latitude1, longitude1));
points.add(new LatLng(latitude2, longitude2));

googleMap.addPolyline(new PolylineOptions().addAll(points));

How do I customize Google Maps embed?

Customizing Google Maps embed can be a valuable way to personalize the map according to your needs or the specific requirements of your website. Here’s a step-by-step guide on how to do it:

1. Get the Google Maps embed code: Start by finding the location or map you want to embed on the Google Maps website. Once you’ve located it, click on the three horizontal lines at the top left, select "Share or embed map," and then click on "Embed map." Copy the generated HTML code.

2. Customize the embed code: Paste the copied code into your website’s HTML file or content management system (CMS). From there, you can modify the attributes in the code to customize the appearance and behavior of the embedded map. Here are some options to consider:

– Changing the map width and height: Locate the "width" and "height" attributes in the embed code and adjust their values to fit your desired dimensions.

– Zoom level: You can set a specific zoom level by appending "&zoom=" followed by the desired value, such as "&zoom=10". Experiment with different values to find what suits your needs best.

– Map controls: To enable or disable specific controls on the map, add or remove the corresponding attributes within the code. For example, "&zoom=10&maptype=roadmap" would enable the zoom control and select the roadmap view.

– Markers: You can add markers to signify specific locations on the map. To do this, modify the code by appending "&markers=" followed by the latitude and longitude coordinates of the location. For example, "&markers=latitude,longitude".

– Styles: Google Maps allows you to customize the map’s visual appearance using a JSON-based map style. You can find pre-defined styles on the Snazzy Maps website (snazzymaps.com) or create your own using the Google Maps Styling Wizard.

3. Test and implement: Once you’ve made your desired customizations to the embed code, save the changes and preview the map on your website. Ensure that everything appears as intended and operates correctly.

By following these steps and manipulating the attributes within the Google Maps embed code, you can fully customize the map to fit your website’s design aesthetic and provide the functionality you desire.
