Quickstart

Install and render your first map

Add the SDK

// build.gradle.kts
dependencies {
    implementation("com.machinestalk:indoornavigationengine:1.0.0")

compileOptions {
    sourceCompatibility = JavaVersion.VERSION_17
    targetCompatibility = JavaVersion.VERSION_17
}
kotlinOptions {
    jvmTarget = "17"
}

Render a map (Compose)

@Composable
fun VenueMap() {
    val context = LocalContext.current
    val mapData = remember { JsonUtil.LoadJsonFromAsset(context, "map.json") }

    IndoorNavigationScene(
        mapBuild = mapData,
        theme = MapTheme.Dark,           // or Light/Custom
        cameraConfig = CameraConfig.Default
    )
}

Load maps remotely

suspend fun fetchMap(): MapBuild {
    val loader = MapLoader()
