The second area that has some differences is the gradle configuration. Let's look at build.gradle.

Besides the dependencies and configuration to allow the use of Kotlin, we can see that a new library has been added to the dependencies:

compileOnly 'com.google.android.things:androidthings:+'

This is the counterpart of the library we have declared on the Manifest. The gradle dependency is marked as compileOnly, which means that the library is expected to be installed on the target device and will not be included in the code of the application.
