title: Android APK Raw File Size vs Download Size. How to shrink the Raw File Size?
body: <p>I'm using Android Studio 3.0. When I Analyze my APK, I see the following</p>
  
  <pre><code>Raw File Size: 4.1 MB, Download Size 3.3 MB.
  </code></pre>
  
  <p>Why is that different? </p>
  
  <p>Since this is an Instant App, it prevents it from being uploaded. How could I shrink the Raw File Size without need to change my code/resource that is needed on download?</p>
