I don't find the class NmeaGpsDriver in any androidthings: https://mvnrepository.com/artifact/com.google.android.things/androidthings Do you have a jar? or what class I cound used instead?
That class is an extension of the built in GNSS driver. It's in fact available as one of the provided sample drivers on GitHub.
You can import it with:
implementation 'com.google.android.things.contrib:driver-gps:1.0'
