Use Map IDs

A map ID is an identifier that's associated with a specific map style or feature. Configure a map style and associate it with a map ID in the Google Cloud Console. Then, when you reference a map ID in your code, its associated map style is displayed in your app. Any subsequent style updates you make appear in your app automatically, without the need for any updates by your customers.

Upon creation, map IDs are associated with a project, and are also restricted to a single platform (Android, iOS, JavaScript) or to the Maps Static API.

To create or manage any map IDs in your Cloud Console, you must have the Project Owner or Project Editor IAM role.

Required permissions

To create or manage any map IDs or map Styles in a given Google Cloud project, you must hold either the Owner or Editor IAM role on the project.

Create a map ID

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 Cloud Console.

To create a map ID:

  1. In the Cloud Console, go to the Maps Management page.
  2. Select Create New Map ID to display the Create New Map ID form.
    Create New Map ID

    In the form, do the following:

    • Specify a map name.
    • Specify a map type or platform.
    • For JavaScript maps, choose raster or vector map type.
    • Enter a description of the map.
    • Select Next to display the new map ID.

Associate a map ID to a map style

These instructions assume that there is at least one existing map style in your project.

  1. In the Cloud Console, go to the Maps Management page.
  2. On this page, select an existing map ID from the Map name column.
  3. At the bottom of this form, choose a map style from the Map styles associated with this Map ID dropdown.
  4. Select Save.

Add the map ID to your app


Add your map ID through a <fragment> element in the activity’s layout file, by using the MapView class, or programmatically using the GoogleMapOptions class.

For example, assume you created a map ID that is stored as a string value named map_id in res/values/strings.xml:

<?xml version="1.0" encoding="utf-8"?>
<string name="map_id">YOUR_MAP_ID</string>

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 map:mapId attribute:

<fragment xmlns:map=""
    map:mapId="@string/map_id" />

You can also use the map:mapId attribute of the MapView class to specify a map ID:

    map:mapId="@string/map_id" />

To specify a map ID programmatically, pass it to a MapFragment instance using the GoogleMapOptions class:


 MapFragment mapFragment = MapFragment.newInstance(
     new GoogleMapOptions()


 val mapFragment = MapFragment.newInstance(

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.


To instantiate a map using a map ID, do the folowing:

  1. Create a GMSMapID with the map ID string from Cloud Console.
  2. Create a GMSMapView specifying the map ID you just created.


let camera = GMSCameraPosition(latitude: 47.0169, longitude: -122.336471, zoom: 12)
let mapID = GMSMapID(identifier: "<YOUR MAP ID>")
let mapView = GMSMapView(frame: .zero, mapID: mapID, camera: camera)
self.view = mapView


GMSCameraPosition *camera = [GMSCameraPosition cameraWithLatitude:47.0169
GMSMapID *mapID = [GMSMapID mapIDWithIdentifier:@"<YOUR MAP ID>"];
GMSMapView *mapView = [GMSMapView mapWithFrame:CGRectZero mapID:mapID camera:camera];
self.view = mapView;

If you are using your own map ID, you can set your map ID in the Cloud Console to have a new style at any time, and that style will be reflected on your map view automatically for you and users within about six hours.

If you want to see the changes immediately, you can close out and restart your app by exiting the app, forcing a quit of the app from the recently-used apps list, and then reopening it. The updated map will then be visible.


To create a map with a map ID in your application code:

  1. If you are currently customizing your map with embedded JSON code, remove the styles property from your MapOptions object; otherwise, skip this step.

  2. Add a map ID to the map using the mapId property. For example:

map = new google.maps.Map(document.getElementById('map'), {
center: {lat: -34.397, lng: 150.644},
zoom: 8,
mapId: 'MAP_ID'

Maps Static

To add a map ID to a new or existing map that uses one of our web-service APIs, append the map_id URL parameter and set it to your map ID. This example shows adding a map ID to a map using Maps Static API.

<img src=",New+York,NY&zoom=13&size=600x300&maptype=roadmap&markers=color:blue%7Clabel:S%7C40.702147,-74.015794&markers=color:green%7Clabel:G%7C40.711614,-74.012318&markers=color:red%7Clabel:C%7C40.718217,-73.998284&key=YOUR_API_KEY&map_id=YOUR_MAP_ID&signature=YOUR_SIGNATURE" />

A map centered on the Brooklyn Bridge in New York City, NY, US with map controls in the lower right corner. The map displays custom styling on the roads, water, and land.

If you have a digital signature in your Maps Static URL before adding your map ID, you will need to create and add a new digital signature after adding your map ID. When generating your new URL signing secret, remember to remove your previous digital signature from the URL.
