This document summarizes how to publish Android Wear apps for versions 1.x and 2.x. It explains that for version 1.x, a single APK contained both the phone and watch apps, while for version 2.x the phone and watch apps have separate APKs. It recommends using product flavors and build variants to generate two APKs, one compatible with 1.x and one for 2.x, that can be published to the Google Play Store for Wear.
