## Choose Your Provider

For iOS, you have the option to choose between Apple Maps or Google Maps. On Android, only Google Maps is available. Google Maps provides more custom style options from different map types to coloring and exposing or hiding map features.

### Add Google Maps API Key

You can live-test your app without adding your unique Google Maps API keys, but you need to add them if you want to download or publish your app. 

#### Generate a Google Maps API Key

To generate your personal Google Maps API key, you need to:

1. Create a Google Cloud project for your app.
2. Create a billing account or enable billing for the project.
3. Click **Enable** to enable the Maps SDK for Android or Maps SDK for iOS.  
4. Select **Enable all Google Maps APIs for this project**.\

#### Add Google Maps API Key to Thunkable&#x20;

Once you've generated your Google Maps API keys, you can add them to your Thunkable project. Click the gear icon at the top of the components tree on your project's designer tab to access your [Project Settings](https://docs.thunkable.com/snap-to-place/projects/settings). Scroll to the **Google Map Settings** section and paste your Android and iOS API keys into the corresponding fields.&#x20;

### Events

The map has several events. You can trigger actions to happen when these events occur.

#### On Map Ready

This event happens when the Map has loaded in your app.&#x20;

This is a good time to add any markers, polylines or polygons to your app that you want the user to see as soon as your app opens.

![](https://689802330-files.gitbook.io/~/files/v0/b/gitbook-legacy-files/o/assets%2F-LAn5scXl2uqUJUOqkJo%2F-MXm-VzBm17M2Y4a2Gq1%2F-MXm1Kgoc6OY6Tr1vFSc%2FScreen%20Shot%202021-04-08%20at%204.10.55%20PM.png?alt=media\&token=98424ab5-52e1-4f9a-8e24-d6f909a61a27)

#### On User Location Change

This event happens when the location of the user changes. It returns the **coordinate** object.\
You can use [object blocks](https://docs.thunkable.com/snap-to-place/objects) to get the properties of the coordinate object.

The **coordinate** object has the following properties:

**{**\
&#x20;   **target:** Numeric ID for your app\
&#x20;   **coordinate:{**\
&#x20;         **latitude:** latitude of point selected\
&#x20;         **longitude:** longitude of point selected \
&#x20;   **}**\
&#x20;   **position:{**\
&#x20;         **x:** x-position of selected point on the Map component\
&#x20;         **y:** x-position of selected point on the Map component\
&#x20;   **}**\
**}**

#### On Marker Press

This event happens when the user clicks on a Marker that is on the Map.

The **On Marker Press** block returns an **event** object. This is an object which can be used with [object blocks.](https://docs.thunkable.com/snap-to-place/objects)&#x20;

The **event** object has the following properties:

{\
&#x20;   **latitude:** latitude of the selected Marker\
&#x20;   **longitude**: longitude of the selected Marker\

You can pair the Map component with a [Location Sensor](https://docs.thunkable.com/snap-to-place/location-sensor). This helps you show content relevant to the user's location.

These blocks will set the map's latitude and longitude to show the user's location once the map is ready:
