title: How to update/upgrade your Android APK during Staged Rollout in Google Play
body: <p>I recently used Google Play's "Staged Rollout" feature and slowly published my company's (redesigned) V2 of its Android app.</p>
  
  <p>Although it was very simple (<a href="https://support.google.com/googleplay/android-developer/answer/3131213">following the instructions</a>) to roll out the new APK at an initial percentage rate; it was not intuitive to update/upgrade the APK when I needed to publish a hotfix to only those (users) in staged rollout.</p>
  
  <p>So how did I do it?  See my answer below.</p>
