Map Kit is an SDK for map development. It covers map data of more than 200 countries and regions, and supports hundreds of languages. With this SDK, you can easily integrate map-based functions into your apps.
HUAWEI Map Kit uses the WGS 84 GPS coordinate system, which meets most map development requirements outside China, including:
Map display: Displays buildings, roads, water systems, and Points of Interest (POIs).
Map interaction: Controls the interaction gestures and buttons on the map.
Map drawing: Adds location markers, map layers, overlays, and various shapes.
- First, you need to register a Huawei Developer account. You can register it for free from the link below.
https://id5.cloud.huawei.com/CAS/portal/userRegister/regbyemail.html
- After opening the developer account, we will create a project
- And open an application in the project.
- Need to adjust the settings of the application. Since it is a sample project, I share all the information with you.
- Need to produce SHA-256 certificate fingerprints. We click on the Gradle area on the right in Android Studio.
- Clicking the signingReport button under Tasks, we generate sha 256 code. We add it to the relevant field in the project settings.
- Need to activate MapKit from the Manage API section.
- Download the
agconnect-services.jsonfile. Then we add it to the app folder of our project.
- Define the necessary permissions in the
AndroidManifest.xmlfile.
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<uses-permission android:name="com.huawei.appmarket.service.commondata.permission.GET_COMMON_DATA" />
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />- In the
build.gradle(HuaweiMapKitApp)field, we add the necessary codes for Huawei Map Kit.
buildscript {
ext.kotlin_version = "1.6.21"
repositories {
google()
mavenCentral()
maven { url 'https://developer.huawei.com/repo/' }
}
dependencies {
classpath 'com.android.tools.build:gradle:7.2.1'
classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
classpath 'com.huawei.agconnect:agcp:1.6.0.300'
}
}
allprojects {
repositories {
google()
mavenCentral()
maven {
url 'https://developer.huawei.com/repo/'
}
}
}
task clean(type: Delete) {
delete rootProject.buildDir
}- Add the plugin in
build.gradle(:app)
plugins {
id 'com.android.application'
id 'kotlin-android'
id 'com.huawei.agconnect'
}- Add the Map Kit dependency in
build.gradle(:app)
dependencies {
implementation 'androidx.core:core-ktx:1.7.0'
implementation 'androidx.appcompat:appcompat:1.4.1'
implementation 'com.google.android.material:material:1.6.0'
implementation 'androidx.constraintlayout:constraintlayout:2.1.4'
implementation 'com.huawei.hms:maps:6.4.1.300'
}- Now can add map to our layout file (
activity_main.xml).
<?xml version="1.0" encoding="utf-8"?>
<androidx.constraintlayout.widget.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent">
<com.huawei.hms.maps.MapView
xmlns:map="http://schemas.android.com/apk/res-auto"
android:id="@+id/huaweiMapView"
map:uiCompass="true"
map:uiZoomControls="true"
android:layout_width="match_parent"
android:layout_height="match_parent" />
</androidx.constraintlayout.widget.ConstraintLayout>- Make map settings in the
MainActivity.kt. Add a static location information and marker to the map.
class MainActivity : AppCompatActivity(), OnMapReadyCallback {
private lateinit var huaweiMap: HuaweiMap
private lateinit var marker: Marker
private lateinit var cameraUpdate: CameraUpdate
private lateinit var cameraPosition: CameraPosition
private lateinit var binding: ActivityMainBinding
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
// View Binding Settings
binding = ActivityMainBinding.inflate(layoutInflater)
val view = binding.root
setContentView(view)
var mapViewBundle: Bundle? = null
if (savedInstanceState != null) {
mapViewBundle = savedInstanceState.getBundle(MAP_BUNDLE_KEY)
}
binding.huaweiMapView.onCreate(mapViewBundle)
binding.huaweiMapView.getMapAsync(this)
}
// if the map is ready
override fun onMapReady(map: HuaweiMap) {
// mapping
huaweiMap = map
// marker add
marker = huaweiMap.addMarker(
MarkerOptions()
.icon(BitmapDescriptorFactory.defaultMarker()) // default marker
.title("Huawei Turkey") // maker title
.position(LatLng(41.031261, 29.117277)) // marker position
)
// camera position settings
cameraPosition = CameraPosition.builder()
.target(LatLng(41.031261, 29.117277))
.zoom(10f)
.bearing(2.0f)
.tilt(2.5f).build()
cameraUpdate = CameraUpdateFactory.newCameraPosition(cameraPosition)
huaweiMap.moveCamera(cameraUpdate)
}
// constant
companion object {
private const val MAP_BUNDLE_KEY = "MapBundleKey"
}
}- Have done all the necessary actions. Congratulations! 🥳 You have developed the first Huawei Maps application.
