As of version 5.0.0, the library has been rewritten in Kotlin and split into focused submodules so you can depend only on what you need. If you are upgrading from 4.x, see the [migration guide](MIGRATION.md). - **Marker animation** - animates a marker from one position to another - **Marker clustering** — handles the display of a large number of points - **Marker icons** — display text on your Markers - **Heatmaps** — display a large number of points as a heat map - **Import KML** — displays KML data on the map - **Import GeoJSON** — displays and styles GeoJSON data on the map - **Polyline encoding and decoding** — compact encoding for paths, interoperability with Maps API web services - **Spherical geometry** — for example: computeDistance, computeHeading, computeArea - **Street View metadata** — checks if a Street View panorama exists at a given location You can also find Kotlin extensions for this library in [Maps Android KTX][android-maps-ktx].

## Requirements * Android API level 23+ * [Sign up with Google Maps Platform] * A Google Maps Platform [project] with the **Maps SDK for Android** enabled - An [API key] associated with the project above ... follow the [API key instructions] if you're new to the process ## Installation ```kotlin dependencies { // Utilities for Maps SDK for Android (requires Google Play Services) // You do not need to add a separate dependency for the Maps SDK for Android // since this library builds in the compatible version of the Maps SDK. // The aggregator artifact transitively pulls in all submodules below. implementation("com.google.maps.android:android-maps-utils:5.2.0") // x-release-please-version } ``` Alternatively, depend only on the submodules your app needs: ```kotlin dependencies { // Base utilities: PolyUtil, SphericalUtil, collection managers, Street View metadata implementation("com.google.maps.android:android-maps-utils-core:5.2.0") // x-release-please-version // Marker clustering implementation("com.google.maps.android:android-maps-utils-clustering:5.2.0") // x-release-please-version // KML and GeoJSON import implementation("com.google.maps.android:android-maps-utils-data:5.2.0") // x-release-please-version // Heatmaps implementation("com.google.maps.android:android-maps-utils-heatmaps:5.2.0") // x-release-please-version // Marker icons and animation implementation("com.google.maps.android:android-maps-utils-ui:5.2.0") // x-release-please-version } ``` ### Compatibility with Google Navigation SDK for Android If your project integrates the [Google Navigation SDK for Android](https://developers.google.com/maps/documentation/navigation/android-sdk), you must exclude the transitive `play-services-maps` dependency to prevent duplicate class conflicts: ```kotlin configurations.all { if (name.contains("navigation", ignoreCase = true)) { exclude(group = "com.google.android.gms", module = "play-services-maps") } } ``` ## Sample App

This repository includes a [sample app](demo) that illustrates the use of this library. To run the demo app, ensure you've met the requirements above then: 1. Clone the repository 1. Add a file `secrets.properties` in the root project (this file should *NOT* be under version control to protect your API key) 1. Add the following keys to `secrets.properties`: - `MAPS_API_KEY`: **Required**. Your Google Maps API Key. Ensure it has the **Maps SDK for Android** enabled. - `PLACES_API_KEY`: **Optional**. Required for demos using the Places API (e.g., Heatmaps with Places). Ensure the **Places API** is enabled. - `MAP_ID`: **Optional**. Required for demos using Advanced Markers or Cloud-based Map Styling. For example: ```properties MAPS_API_KEY=YOUR_MAPS_API_KEY PLACES_API_KEY=YOUR_PLACES_API_KEY MAP_ID=YOUR_MAP_ID ``` 1. Build and run the `debug` variant for the Maps SDK for Android version ### Setting up the Map ID Some of the features in the demo app, such as Advanced Markers, require a Map ID. You can learn more about map IDs in the [official documentation](https://developers.google.com/maps/documentation/android-sdk/map-ids/mapid-over). You can set the Map ID in one of the following ways: 1. **`secrets.properties`:** Add a line to your `secrets.properties` file with your Map ID: ```properties MAP_ID=YOUR_MAP_ID ``` 2. **`strings.xml`:** Alternatively, you can set the Map ID in the `demo/src/main/res/values/strings.xml` file: ```xml YOUR_MAP_ID ``` 3. **XML Layout Files:** You can also hardcode the Map ID directly in the XML layout files where a map is defined, by setting the `map:mapId` attribute: ```xml ``` ## Documentation See the [documentation] for a full list of classes and their methods. Full guides for using the utilities are published in [Google Maps Platform documentation](https://developers.google.com/maps/documentation/android-sdk/utility). ## Usage

Marker utilities

### Marker utilities - Marker animation [source](https://github.com/googlemaps/android-maps-utils/blob/main/ui/src/main/java/com/google/maps/android/ui/AnimationUtil.kt), [sample code](https://github.com/googlemaps/android-maps-utils/blob/main/demo/src/main/java/com/google/maps/android/utils/demo/AnimationUtilDemoActivity.java) - Marker clustering [source](https://github.com/googlemaps/android-maps-utils/tree/main/clustering/src/main/java/com/google/maps/android/clustering), [guide](https://developers.google.com/maps/documentation/android-sdk/utility/marker-clustering) - Advanced Markers clustering [source](https://github.com/googlemaps/android-maps-utils/tree/main/clustering/src/main/java/com/google/maps/android/clustering), [sample code](https://github.com/googlemaps/android-maps-utils/blob/main/demo/src/main/java/com/google/maps/android/utils/demo/CustomAdvancedMarkerClusteringDemoActivity.java) - Marker icons [source](https://github.com/googlemaps/android-maps-utils/blob/main/ui/src/main/java/com/google/maps/android/ui/IconGenerator.kt), [sample code](https://github.com/googlemaps/android-maps-utils/blob/main/demo/src/main/java/com/google/maps/android/utils/demo/IconGeneratorDemoActivity.java)

Data visualization utilities

### Data visualization utilities - Display heat maps [source](https://github.com/googlemaps/android-maps-utils/tree/main/heatmaps/src/main/java/com/google/maps/android/heatmaps), [guide](https://developers.google.com/maps/documentation/android-sdk/utility/heatmap) - Import GeoJSON [source](https://github.com/googlemaps/android-maps-utils/tree/main/data/src/main/java/com/google/maps/android/data/geojson), [guide](https://developers.google.com/maps/documentation/android-sdk/utility/geojson) - Import KML [source](https://github.com/googlemaps/android-maps-utils/tree/main/data/src/main/java/com/google/maps/android/data/kml), [guide](https://developers.google.com/maps/documentation/android-sdk/utility/kml)

Polyline and spherical geometry utilities

### Additional utilities - Polyline encoding and decoding [source](https://github.com/googlemaps/android-maps-utils/blob/main/library/src/main/java/com/google/maps/android/PolyUtil.kt), [encoding sample](https://github.com/googlemaps/android-maps-utils/blob/main/demo/src/main/java/com/google/maps/android/utils/demo/PolySimplifyDemoActivity.java), [decoding sample](https://github.com/googlemaps/android-maps-utils/blob/main/demo/src/main/java/com/google/maps/android/utils/demo/PolyDecodeDemoActivity.java) - Spherical geometry [source](https://github.com/googlemaps/android-maps-utils/blob/main/library/src/main/java/com/google/maps/android/SphericalUtil.kt), [compute distance sample](https://github.com/googlemaps/android-maps-utils/blob/main/demo/src/main/java/com/google/maps/android/utils/demo/DistanceDemoActivity.java)

Street View metadata utility

### Street View metadata utility The StreetViewUtil class provides functionality to check whether a location is supported in StreetView. You can avoid errors when [adding a Street View panorama](https://developers.google.com/maps/documentation/android-sdk/streetview) to an Android app by calling this metadata utility and only adding a Street View panorama if the response is `OK`. ```kotlin StreetViewUtils.fetchStreetViewData(LatLng(8.1425918, 11.5386121), BuildConfig.MAPS_API_KEY,Source.DEFAULT) ``` `fetchStreetViewData` will return `NOT_FOUND`, `OK`, `ZERO_RESULTS` or `REQUEST_DENIED`, depending on the response. By default, the `Source` is set to `Source.DEFAULT`, but you can also specify `Source.OUTDOOR` to request outdoor Street View panoramas.

## Internal usage attribution ID This library calls the `addInternalUsageAttributionId` method, which helps Google understand which libraries and samples are helpful to developers and is optional. Instructions for opting out of the identifier are provided below. If you wish to disable this, you can do so by removing the initializer in your `AndroidManifest.xml` using the `tools:node="remove"` attribute: ```xml
