title: Why App Bundle weights more than when it's .apk file?
body: <p>My App after installation weighted 12mb when I used good old .apk.
  I wanted to switch using Android App Bundle so I:</p>
  
  <ol>
  <li><p>Used </p>
  
  <blockquote>
    <p>gradlew bundle </p>
  </blockquote></li>
  </ol>
  
  <p>to obtain .aab file (weight: 15mb - for comparison .apk was 16 mb)</p>
  
  <ol start="2">
  <li><p>Used </p>
  
  <blockquote>
    <p>bundletool build-apks
    that produced .apks file that weight 80mb!</p>
  </blockquote></li>
  <li><p>Used </p>
  
  <blockquote>
    <p>bundletool install-apks</p>
  </blockquote></li>
  </ol>
  
  <p>and installed on my phone but just the clean installation <strong>weights 25mb!</strong>
  So instead of weighting less than <strong>previous ~16mb</strong> after installation - it weights more quite significantly.</p>
  
  <p>I tested that on Moto G5, Android Oreo which (drawables are: xxhdpi)</p>
  
  <p>Did I make something wrong ? Maybe it's a bug coming from bundletool ?</p>
  
  <p><strong>EDIT:</strong>
  When using flag --connected-device in step 2. The generated .apks is way smaller but in the end (step 3) the final storage of my app is still 25/26mb :(</p>
