title: How to share a build for testing?
body: <p>I sent the build for testing all the time in this way:</p>
  <ul>
  <li>I build the <code>app-debug.apk</code> and send it to all testers by mail</li>
  <li>I send the release apk for internal testing in Google Play.</li>
  </ul>
  <p>I tried to upload the debug build to internal testing, but after the release builds it does not allow uploading.</p>
  <p>I need to send the debug build to testers, because there is a library for collecting information about requests to the server, or crash logs, etc.</p>
  <p>Question:
  How can I share a debug build with testers via the Play Console?
  And in general, how do you organize all this?
  Heard about <code>CI</code> and <code>CD</code>, but so far my knowledge is not enough for this</p>
