Add a Styled Map | Maps SDK for Android

Stay organized with collections Save and categorize content based on your preferences.

This tutorial shows you how to add a map with custom styling to your Android app. The tutorial uses night mode as an example of custom styling.

With style options you can customize the presentation of the standard Google map styles, changing the visual display of features like roads, parks, businesses, and other points of interest. This means that you can emphasize particular components of the map or make the map complement the style of your app.

Styling works only on the normal map type. Styling does not affect indoor maps.

If you want to update the same style across multiple apps, look into cloud customization, which is available in the Google Cloud console and requires a map ID. To avoid potential conflicts, do not combine cloud customization and hardcoded styling in the same app. Get the code

Clone or download the Google Maps Android API v2 Samples repository from GitHub.

Set up your development project

Follow these steps to create the tutorial project in Android Studio.

Download and install Android Studio.
Add the Google Play services package to Android Studio.
Clone or download the Google Maps Android API v2 Samples repository if you didn't do that when you started reading this tutorial.
Import the tutorial project:
- In Android Studio, select File > New > Import Project.
- Go to the location where you saved the Google Maps Android API v2 Samples repository after downloading it.
- Find the StyledMap project at this location:
  PATH-TO-SAVED-REPO/android-samples/tutorials/StyledMap
- Select the project directory, then click OK. Android Studio now builds your project, using the Gradle build tool.

Get an API key and enable the necessary APIs

To complete this tutorial, you need a Google API key that's authorized to use the Maps SDK for Android.

Click the button below to get a key and activate the API.

Get a Key

For more details, see the Get an API Key guide.

Add the API key to your app

Edit your project's gradle.properties file.
Paste your API key into the value of the GOOGLE_MAPS_API_KEY property. When you build your app, Gradle copies the API key into the app's Android manifest.
```
GOOGLE_MAPS_API_KEY=PASTE-YOUR-API-KEY-HERE
```

Build and run your app

Connect an Android device to your computer. Follow the instructions 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 to configure a virtual device. When choosing an emulator, make sure you pick an image that includes the Google APIs. For more details, see the getting started guide.)
In Android Studio, click the Run menu option (or the play button icon). Choose a device as prompted.

Android Studio invokes Gradle to build the app, and then runs the app on the device or on the emulator. You should see a map with dark (night mode) styling, similar to the image on this page.

Troubleshooting:

If you don't see a map, check that you've obtained an API key and added it to the app, as described above. Check the sign in on Android Studio's Android Monitor for error messages about the API key.
Use the Android Studio debugging tools to view logs and debug the app.

Understand the code

This part of the tutorial explains the most significant parts of the StyledMap app, to help you understand how to build a similar app.

Add a resource containing a JSON style object

Add a resource to your development project, containing your style declarations in JSON format. You can use a raw resource or a string, as shown in the examples below.

Note: The sample app that you downloaded from GitHub uses a raw resource. Raw resource

Define a raw resource in /res/raw/style_json.json, containing the JSON style declaration for night-mode styling:

Pass a JSON style object to your map

To style your map, call GoogleMap.setMapStyle() passing a MapStyleOptions object that contains your style declarations in JSON format.

More about JSON style declarations

Styled maps use two concepts to apply colors and other style changes to a map:

Selectors specify the geographic components that you can style on the map. These include roads, parks, bodies of water, and more, as well as their labels. The selectors include features and elements, specified as featureType and elementType properties.
Stylers are color and visibility properties that you can apply to map elements. They define the displayed color through a combination of hue, color, and lightness and gamma values.

See the style reference for a detailed description of the JSON styling options.

Maps Platform Styling Wizard

Use the Maps Platform Styling Wizard as a quick way to generate a JSON styling object. The Maps SDK for Android supports the same style declarations as the Maps JavaScript API.

Note: To have a style apply to multiple app platforms, consider using cloud-based maps styling. If you want to use a JSON style, you can import it. For details, see Import a JSON map style. Next step

See how to hide features on the map with styling.
