Answer 1

This error usually happens when you add dependencies, which uses different versions of some classes under the hood, and build tool can't figure out which version of a class it have to use (in your case it's classes from com.google.android.maps:navsdk:4.3.2, com.google.android.gms:play-services-maps:17.0.0).

To get rid of this error you should consider to upgrade some of your libraries.

Note: there is a command which will help you to debug your problem: ./gradlew app:dependencies. It shows dependencies tree of a project, so you could faster detect dependencies which are used by your libraries.
