crash when i try to create a path between two points in osmdroid

Question

I have recently started studying android and kotlin programming, I'm trying to create an application that allows you to create one or more routes on a map, save it and then retrieve it when necessary. I chose to use osmDroid and osmBonusPack because open source but I don't find much documentation online, I'm trying to visualize a path between two Markers, I was able to visualize two markers and draw a straight line between two other points, now I'm trying to make the path but I don't understand how to proceed. Following the tutorial:

https://github.com/MKergall/osmbonuspack/wiki/Tutorial_1

trying to put some println("check") i understand that the app crashes when it gets to the line:

val road: Road = roadManager.getRoad(waypoints)

what's my problem? what is the error:

E/AndroidRuntime: FATAL EXCEPTION: main Process: uk.co.lorenzopulcinelli.trackapp, PID: 28815 java.lang.NoClassDefFoundError: Failed resolution of: Lokhttp3/Request$Builder;

Answer 1

I found the solution by importing dependencies that I had overlooked I followed the answer to this question:

Unable to resolve dependency for retrofit2

in particular it was enough to add these dependencies, these in my app build.gradle file:

implementation 'com.squareup.retrofit2:retrofit:2.4.0'
implementation 'com.google.code.gson:gson:2.8.2'
implementation 'com.squareup.retrofit2:converter-gson:2.4.0'
implementation 'com.squareup.okhttp3:logging-interceptor:3.4.1'
implementation 'com.squareup.okhttp3:okhttp:3.10.0'

and these in my project build.gradle file:

allprojects {
    repositories {
        google()
        maven { url "https://jitpack.io" }
        jcenter()
    }
}
