zsmb13 :

The error is caused by the old version of Kotlin in your project level file, you can update it to the latest version like so:

ext.kotlin_version = '1.3.21'

As for your warnings:

• You should remove the explicit build tools version (buildToolsVersion "26.0.2") from your module level file, as the new Android Gradle plugins already pick the correct build tools to use automatically.
• You should check out the link in the warnings and update your dependency configuration, e.g. replace compile with implementation or api, and so on.
