The sample code for the Watch Face contains the following comment

Important Note: Because watch face apps do not have a default Activity in their project, you will need to set your Configurations to "Do not launch Activity" for both the Wear and/or Application modules. If you are unsure how to do this, please review the "Run Starter project" section in the Google Watch Face Code Lab: https://codelabs.developers.google.com/codelabs/watchface/index.html#0

Answer 3

I also had an issue similar to this after adding a Watchface, and thought I would chime in with what fixed it for me.

In Android Studio 2.2.1: Run -> Edit -> Your App -> watchface -> General -> Launch Options -> Launch: Nothing

By default, mine was selected to run the default activity, which is incorrect for a watch face.
