title: Android: do I actually need to register in App Center to migrate from the HockeySDK?
body: <p>I inherited a (fairly large) Android app; it's still in beta.</p>
  <p>I recently got an email from Google Play:</p>
  <pre><code>&quot;Action Required: Your app is not compliant with Google Play Policies ...
  We found your app is using a non-compliant version of Hockey SDK...&quot;
  </code></pre>
  <p>OK. I learned that Microsoft acquired the company a few years ago and, last fall, transitioned the functionality to their (open source) <a href="https://docs.microsoft.com/en-us/appcenter/sdk/getting-started/android" rel="nofollow noreferrer">App Center SDK</a> and deprecated the old HockeySDK.  Microsoft also published a nice, straightforward <a href="https://docs.microsoft.com/en-us/appcenter/transition/android-sdk-migration" rel="nofollow noreferrer">Migration Guide</a>.</p>
  <p>What the migration DOESN'T explicitly say is whether or not one MUST register on the App Center.</p>
  <p>The new App Center SDK requires this:</p>
  <pre><code>AppCenter.start(getApplication(),
      &quot;{Your App Secret}&quot;, 
      Analytics.class, Crashes.class, Distribute.class);
  </code></pre>
  <p>Q: The &quot;App Secret&quot; is <em>NOT</em> the old Hockey App ID (e.g. &quot;00112233445566778899aabbccddeeff&quot;), correct?</p>
  <p>Q: The only way to get an &quot;App Secret&quot; is to register on the App Center, correct?</p>
  <p>Q: I'm definitely <em>NOT</em> going to purchase the $50/month subscription to App Center.  Is there any downside to just commenting out the old Hockey SDK register (and unregister) calls from the app?</p>
