This is a Kotlin Multiplatform library that provides controls of maps to common code.
Table of Contents
Features
- Markers - add markers to map from common code;
- Route - draw route by waypoints from common code;
- Camera - control camera (zoom, location) from common code.
Requirements
- Gradle version 6.0+
- Android API 16+
- iOS version 9.0+
Installation
root build.gradle
allprojects {
repositories {
mavenCentral()
maven { url = "https://mapbox.bintray.com/mapbox" } // if mapbox required
}
}project build.gradle
dependencies {
commonMainApi("dev.icerock.moko:maps:0.6.0")
commonMainApi("dev.icerock.moko:maps-google:0.6.0")

kotlin.targets
.matching { it is org.jetbrains.kotlin.gradle.plugin.mpp.KotlinNativeTarget }
.configureEach {
val target = this as org.jetbrains.kotlin.gradle.plugin.mpp.KotlinNativeTarget
target.binaries
.matching { it is org.jetbrains.kotlin.gradle.plugin.mpp.Framework }
.configureEach {
val framework = this as org.jetbrains.kotlin.gradle.plugin.mpp.Framework
val frameworks = listOf("Base", "Maps").map { frameworkPath ->
project.file("../ios-app/Pods/GoogleMaps/$frameworkPath/Frameworks").path.let { "-F$it" }
}.plus(
project.file("../ios-app/Pods/Mapbox-iOS-SDK/dynamic").path.let { "-F$it" }
)
framework.linkerOpts(frameworks)
}
}With mobile-multiplatform-gradle-plugin cocoapods configuration simplest:
build.gradle.kts:
cocoaPods {
podsProject = file("ios-app/Pods/Pods.xcodeproj")
precompiledPod(
scheme = "GoogleMaps",
onlyLink = true
) { podsDir ->
listOf(
File(podsDir, "GoogleMaps/Base/Frameworks"),
File(podsDir, "GoogleMaps/Maps/Frameworks")
)
}
precompiledPod(
scheme = "Mapbox",
onlyLink = true
) { podsDir ->
listOf(File(podsDir, "Mapbox-iOS-SDK/dynamic"))
}
}project Podfile
pod 'GoogleMaps', '3.7.0'
pod 'Mapbox-iOS-SDK', '5.5.0'
# GoogleMaps is static library that already linked in moko-maps-google. Remove duplicated linking.
post_install do |installer|
host_targets = installer.aggregate_targets.select { |aggregate_target|
aggregate_target.name.include? "Pods-"
}
host_targets.each do |host_target|
host_target.xcconfigs.each do |config_name, config_file|
config_file.frameworks.delete("GoogleMaps")
config_file.frameworks.delete("GoogleMapsBase")
config_file.frameworks.delete("GoogleMapsCore")
xcconfig_path = host_target.xcconfig_path(config_name)
config_file.save_as(xcconfig_path)
end
end
endUsage
Markers
class MarkerViewModel(
val mapsController: GoogleMapController
) : ViewModel() {
fun start() {
viewModelScope.launch {
val marker1 = mapsController.addMarker(
image = MR.images.marker,
latLng = LatLng(
latitude = 55.045853,
longitude = 82.920154
),
rotation = 0.0f
) {
println("marker 1 pressed!")
}
marker1.rotation = 90.0f
}
}
}Route
class MarkerViewModel(
val mapsController: GoogleMapController
) : ViewModel() {
fun start() {
viewModelScope.launch {
val route = mapsController.buildRoute(
points = listOf(
LatLng(
latitude = 55.032200,
longitude = 82.889360
),
LatLng(
latitude = 55.030853,
longitude = 82.920154
),
LatLng(
latitude = 55.013109,
longitude = 82.926480
)
),
lineColor = Color(0xCCCC00FF),
markersImage = MR.images.marker
)
}
}

Set Up Locally
Before open project need to setup gradle.properties with tokens:
# mapbox tokens by guide https://docs.mapbox.com/android/maps/guides/install/
mapbox.secretToken=YOUR_SECRET_MAPBOX_KEY
mapbox.publicToken=YOUR_PUBLIC_MAPBOX_KEY
# google maps api key by guide https://developers.google.com/maps/documentation/android-sdk/get-api-key
googleMaps.apiKey=YOUR_API_KEY
ios info.plist setup with tokens:
MGLMapboxAccessToken=YOUR_PUBLIC_MAPBOX_KEY
GoogleAPIkey=YOUR_API_KEY
add the following entry to your .netrc file:
machine api.mapbox.com
login mapbox
password YOUR_SECRET_MAPBOX_KEY
- The maps directory contains the base classes for all maps providers;
- The maps-google directory contains the Google Maps implementation;
- The maps-mapbox directory contains the mapbox implementation;
- In sample directory contains sample apps for Android and iOS; plus the mpp-library connected to the apps.
before compilation of iOS target required pod install in sample/ios-app directory
Contributing
All development (both new features and bug fixes) is performed in the develop branch. This way master always contains the sources of the most recently released version. Please send PRs with bug fixes to the develop branch. Documentation fixes in the markdown files are an exception to this rule. They are updated directly in master.
The develop branch is pushed to master on release.
