title: Android Wear 2.0 support for watch face app
body: <p>I have an Android watch face app that has both mobile and wear modules.</p>
  <p>I want to get this app ready for 2.0 update, and I've visited all the websites that Android Developers suggest, I understand almost everything that's about to change, but then comes reality, and I'm stuck with a first simple steps.</p>
  <p>As I read <a href="https://developer.android.com/wear/preview/features/standalone-apps.html" rel="nofollow noreferrer">here</a>:</p>
  <blockquote>
  <p>If you build a standalone Wear 2.0 APK and will continue to have a Wear 1.0 APK, please do both of the following:</p>
  <p>Provide a standalone version of the Wear APK, and Continue embedding a version of the Wear APK in your phone APK</p>
  </blockquote>
  <p>Then <a href="https://developer.android.com/wear/preview/features/app-distribution.html#console" rel="nofollow noreferrer">here</a> we have:</p>
  <blockquote>
  <p>If your app supports both Wear 1.x and Wear 2.0, continue embedding the Wear 1.x APK (minimum SDK version of 20, 21, or 22, or 23) in the phone APK and upload the phone APK. In addition, upload your standalone Wear 2.0 APK (which has a minimum SDK version of 24).</p>
  </blockquote>
  <p>So as I want to keep support for Android 1.x, what do I do exactly?</p>
  <p>How do I set SDK version numbers in modules?</p>
  <p>Do I need to duplicate wear module with changed SDK version for building a separate wearable apk?</p>
  <p>Gold and kingdom for anyone that has done it successfully and would present all the necessary steps for making the app compatible for current and upcoming Wear versions.</p>
