The following instructions show how to use the Google Cloud console to create, customize, publish, and manage your maps at any time using Map IDs and Map Styles.
To create or manage any Map IDs or Map Styles in your Google Cloud project, you must have the Project Owner or Project Editor IAM role.
Creating Map IDs
A Map ID is a unique identifier that represents a single instance of a Google Map. You can create Map IDs and update a style associated with a Map ID at any time in the Google Cloud Console without changing embedded JSON styling in your application code.
To create a Map ID:
In the Cloud Console, go to the Maps Management page.
Click Create New Map ID, to display the Create New Map ID form.
In the form, do the following:
- Specify a map name.
- Specify a map type or platform.
- Enter a description of the map.
- Click Next to display the new Map ID.
Installing Maps SDK for Android Beta
Maps customization features are not yet available in the Google Play Services Maps Library. To test them, use the standalone Beta Maps SDK for Android.
For instructions on how to download the beta SDK, see Installing Maps SDK for Android v.3.1.0 BETA
Adding Map IDs to the existing MapFragment
You can add your Map ID through a
<fragment> element in
the activity’s layout file, by using the
MapView class, or
programmatically using the
For example, assume you created a Map ID that is stored as
a string value named
<?xml version="1.0" encoding="utf-8"?> <resources> <string name="map_id">YOUR_MAP_ID</string> </resources>
For maps added through a
<fragment> element in
the activity’s layout file, all map fragments that should have
the custom style must specify the Map ID in the
<fragment xmlns:map="http://schemas.android.com/apk/res-auto" class="com.google.android.libraries.maps.SupportMapFragment" … map:mapId="@string/map_id" />
You can also use the
map:mapId attribute of the
to specify a Map ID:
<com.google.android.gms.maps.MapView xmlns:android="http://schemas.android.com/apk/res/android" .... map:mapId="@string/map_id" />
To specify a Map ID programmatically, pass it to a
MapFragment mapFragment = MapFragment.newInstance( new GoogleMapOptions() .mapId(getResources().getString(R.string.map_id)));
val mapFragment = MapFragment.newInstance( GoogleMapOptions() .mapId(resources.getString(R.string.map_id)) )
In Android Studio, build and run your app as you normally would. Custom styles, as configured in the first step, will be applied to all maps with an ID.
Creating Map Styles
A Map Style is a unique identifier for a set of customizations that can be associated with any Map ID.
To create a new style:
In the Cloud Console, go to the Map Styles page.
Click Create New Map Style to open the Create New Style page.
In the Create New Style page, you can do the following:
Select a Map Style from one of the available templates, or import existing JSON styling code by pasting your JSON code into the text box on the Import JSON tab.
Apply styling to a map by selecting map names. A single map style can be applied to multiple maps. You can always change the Map Style associated with a Map ID later.
Customize the display of different map features by clicking the Customize in Style Editor button. In the Style Editor, you can:
- Change the styling of features on a map, such as roads, bodies of water, and commercial corridors.
- Filter points of interest to specific business types.
- Specify the display of points of interest density.
Create a name and description to Save or Publish the Map Style. If you associate a Map ID with your Map Style, saving and publishing will make the style changes public for the associated maps. Saving style customizations without publishing in the style editor will not make the changes publicly visible.
Updating style details
On the Map Styles page, you can select a map style to complete the following actions:
- Continue customizing or view style details in the style editor by clicking the Customize style button.
- Rename or edit a description for the style by clicking the Edit button.
- Duplicate the style by clicking the Duplicate button.
- Delete the style by clicking the Delete button.
- View Map IDs associated with the style.
Styles created before September 15, 2020 will not display Google Maps enhanced natural features. To use Google Maps enhanced natural features support for your map styling, you must create a Map Style.
Customizing at different zoom levels
You can customize the style of existing elements at different zoom levels when creating map styles with the style editor in Google Cloud console.
For example, you can customize the color of water from pink at zoom level 0 to purple at zoom level 10, and associate other customizations with the level of detail you see at the specified zoom. To try out this feature in a sample app, run the ApiDemos sample app (GitHub sample for Java | Kotlin) and view the CloudBasedMapStylingActivity demo (GitHub sample for Java | Kotlin).
To make style customizations at different zoom levels:
- Open the style editor in Cloud Console. To do this, visit the Map Styles page, and either create a Map Style or update an existing Map Style.
- Select a feature in the Feature type submenu to open up the Element type submenu, and select an element you would like to customize.
Check the Customize across zooms checkbox to make customizations at the current zoom level appear in the style editor.
Once you select the Customize across zooms checkbox, you should see the following:
- An Add stop: z checkbox that indicates your current zoom level and attaches customizations to the indicated zoom level.
- A zoom slider bar to modify and select your zoom level. You can adjust zoom levels with map boolean zoom controls, mousewheel, or arrow keys on your keyboard.
When you make customizations in the Stylers submenu, the style editor automatically selects the Add stop: z checkbox, displays a blue dot above the slider, and overrides any inherited styles.
The blue dot above your slider indicates that changes were made at the selected zoom level. To prevent changes from being saved at a particular zoom level, clear the Add stop: z checkbox (the blue dot turns gray to indicate that changes will not be saved at that level). After clearing the checkbox, the element returns to its inherited style.
Any customizations you make at a zoom level will update the customizations at the indicated zoom levels and above. For example, customizations at zoom level 10 affect all customizations at zoom levels 10, 11, 12 and so on. The customizations override any inherited styles.
To save your changes, click Save. To make your changes public on the map IDs associated with your map style, click Publish.
Once your app is delivered to customers, custom styles for maps with Map IDs can be updated from Google Cloud console. The new styles will be reflected in your app in a few hours.
To make sure new custom styles show up immediately for testing purposes, clear app data from your test device. For more information on clearing data from your device, see Android Help - Free Up Space.
Note that settings can vary by phone. For more information, contact your device manufacturer.
