Is there a more kotlin friendly way to do string formatting?

Steps to replicate the issue.
-
Use the API key which has a predefined style with some custom layers created using mapbox studio.
-
Apply the style using setStyleUrl()
-
Try to add this layer in
onStyleLoaded()callback.
It was throwing a segmentation fault error when I tried this.

The issue was caused because I was trying to add the source before the style has loaded. I tried adding source and layer both in onStyleLoaded callback and its working.

I'm glad to hear that @iamanvesh! Let us know if you run into any other issues.
Refs #2450.
Adds an example of how to build a class that is responsible for handling dragged symbols and disptaching callbacks with the drag state.
Also, adds Kotlin dependencies to the test app.
