Follow these steps to get set up with data-driven styling for boundaries.

An upgraded map renderer is available as of version 18.0.0 of the Maps SDK for Android. This renderer brings many improvements, including support for Cloud-based maps styling, to Maps SDK for Android.

With the release of version 18.2.0 of the Maps SDK for Android, Google switched the default renderer from the legacy renderer to the upgraded map renderer. This change means that the upgraded map renderer is now used by default in your app when you build a new app or rebuild an existing app.

To create a new map ID, follow the steps at Create a map ID. Make sure you set the Map type to Android.

To create a new map style, follow the instructions in Manage map styles to create the style, and associate the style with the map ID you just created.

In the Google API Console you can select which feature layers to display for your new map style. The feature layer determines which kinds of boundaries appear on the map (for example localities, states, and so on).

1. In the Google API Console, go to the Map Styles page.
2. Select a project if prompted.
3. Select a map style.
4. Click the Feature layers drop-down to add or remove layers.
5. Click Save to save your changes and make them available to your maps.

This step requires the map ID you just created. It can be found on your Maps Management page.

To add the map ID to your initialization code, see Add the map ID to your app.

You use a FeatureLayer object to represent each feature layer of a map, such as a Postal Code or Locality feature layer. To get access to a feature layer object, call GoogleMap.getFeatureLayer() when the map initializes:

private FeatureLayer postalCodeLayer;

@Override
public void onMapReady(GoogleMap map) {
  // Get the POSTAL_CODE feature layer.
  postalCodeLayer = map.getFeatureLayer(new FeatureLayerOptions.Builder()
    .featureType(FeatureType.POSTAL_CODE)
    .build());
  ...
}

private var postalCodeLayer: FeatureLayer? = null

override fun onMapReady(googleMap: GoogleMap) {
  // Get the POSTAL_CODE feature layer.
  postalCodeLayer = googleMap.getFeatureLayer(new FeatureLayerOptions.Builder()
    .featureType(FeatureType.POSTAL_CODE)
    .build())
  ...
}

Pass a FeatureLayerOptions object to getFeatureLayer() to specify the type of the feature layer. In this example, you want to access the POSTAL_CODE layer. Create a different FeatureLayer object for each layer that you want to style.

Once you have the FeatureLayer object, you can apply styling to the boundary polygons in that feature.

Data-driven styling for boundaries requires a map ID. If the map ID is missing, or an invalid map ID is passed, data-driven styling for boundaries cannot load. As a troubleshooting step, you can use MapCapabilities to check if data-driven styling for boundaries is supported.

val capabilities: MapCapabilities = googleMap.getMapCapabilities()
System.out.println("Data-driven Styling is available: " + capabilities.isDataDrivenStylingAvailable())

MapCapabilities capabilities = googleMap.getMapCapabilities();
System.out.println("Data-driven Styling is available: " + capabilities.isDataDrivenStylingAvailable());
