I'm trying to add TomTom
maps to my android application that is built with Kotlin
, but it gives me the error Tomtom Maps SDK for android failed to load tile
and shows an empty map as shown in the image below :
And here are my files and detailed configurations I'm using:
allprojects {
repositories {
google()
jcenter()
maven {
url "https://maven.tomtom.com:8443/nexus/content/repositories/releases/"
}
}
}
dependencies {
implementation("com.tomtom.online:sdk-maps:2.4244")
}
APK
to the AndroidManifests
file : <meta-data
android:name="OnlineMaps.Key"
android:value="<my-Key-here>" />

Two possible points to check:
Your API key is not valid. Please check your API key by calling a raw TomTom Maps endpoint: https://api.tomtom.com/map/1/tile/basic/main/0/0/0.png?key=your_api_key and if you are not able to see the map tile image - register your new API key by going to TomTom Developer Portal and check again.
Your API key is placed in the wrong place inside AndroidManifest.xml file. Make sure that it's placed inside the <application>
tag, next to <activity>
tag.
