MapLibre Compose Playground

This project is based off of https://github.com/ramani-maps/ramani-maps [MPL-2.0 License] and takes a different approach to top level API, emphasizing parity with https://github.com/maplibre/swiftui-dsl for https://github.com/stadiamaps/ferrostar.

Getting Started

This library is published through Maven Central. In your app build.gradle add:

implementation 'io.github.rallista:maplibre-compose:0.0.16'

Note: GitHub package manager releases are deprecated but will remain available.

Usage

Interact with Maplibre Native from Jetpack Compose using the MapView.

var mapViewCamera = rememberMapViewCamera()

MapView(
    styleUrl = "https://demotiles.maplibre.org/style.json",
    camera = mapViewCamera
)

Local development in an app

Local development in your Android app projects is a bit tricky, but here's something that mostly works without thoroughly confusing yourself with Maven Local repos. (This is definitely a hack, but it works; suggestions welcome.)

First, do a local release build.

./gradlew assembleRelease

Then, update your build.gradle to reference the locally built AAR (api works as well of course, if you had an API dependency):

implementation files('/path/to/maplibre-compose-playground/compose/build/outputs/aar/compose-release.aar')

You will also need to manually specify any MapLibre dependencies now. For example:

api 'org.maplibre.gl:android-sdk:10.3.1'
api 'org.maplibre.gl:android-plugin-annotation-v9:2.0.2'

Setting an API Key for the Light and Dark Mode Demo

Copy or move api_keys_template.xml from the root directory to app/src/main/res/values/api_keys.xml and add your own API key. The demo uses https://stadiamaps.com as the map style provider, but can easily be adjusted to review with another provider.

Example Scenes

Callback Example - Shows several event callbacks that can be implemented from the MapView.
Camera Example - Shows the basics of camera control using the MapViewCamera.
Dark and Light Mode Example - Shows usage of rememberMapStyleUrl which dynamically changes the map style based on if the system theme is dark mode. The styles are injected using a Compose wrapper in MainActivity.kt (similar to how a MaterialTheme is injected).
Symbol Example - Shows the basics of Composable symbol creation.
