Custom Map Styles

The HERE SDK for Android provides a flexible solution to customize the map by loading custom map schemes.

If you are looking for predefined map styles, see the Quick Start guide for an introduction. The HERE SDK already includes a set of pre-configured map styles such as MapStyle.NORMAL_DAY or MapStyle.SATELLITE.

Create and Load Custom Map Styles

The most flexible solution to customize the map is to create your own map styles using a configuration file generated with the WYSIWYG HERE Style Editor.

To access the HERE Style Editor, please contact your HERE representative.

As soon as you are satisfied with your custom map style, export it and place it into the "assets" directory of your project. If not already added, you can add that folder via Android Studio (Right-click on the project: New -> Folder -> Assets folder). Load the style into a map scene as follows:

// Place the style into the "assets" directory.
// Full path example: app/src/main/assets/mymapstyle.export.json
// Adjust file name and path as appropriate for your project.
String fileName = "mymapstyle.export.json";
AssetManager assetManager = this.getAssets();
try {;
} catch (IOException e) {
    Log.e(TAG, "Error: Map style not found!");

mapView.getMapScene().loadScene("" + fileName, new LoadSceneCallback() {
    public void onLoadScene(@Nullable MapErrorCode mapErrorCode) {
        if (mapErrorCode == null) {
            // ...
        } else {
            Log.d(TAG, "onLoadScene failed: " + mapErrorCode.toString());

In the above snippet, we use Android's AssetManager to verify that the mymapstyle.export.json file exists at the expected location. You only have to load this file. From there, the HERE SDK will find the other files - as exported from the editor. Make sure that all style files are kept together at the same folder level. mymapstyle.export.json is the main file that includes references to the other files. mymapstyle is the name of your custom map style.

Using custom map styles can be very effective to differentiate your app from other map applications. In addition, it is possible to change map styles on-the-fly, for example, to shift the user's attention to certain map elements based on the current state of your app.
