title: How to optimize apk per ABI when using xamarin and visual studio?
body: <p>I have a xamarin forms solution with visual studio 2019 on mac.
  I try to publish my apk on google play console but it says that they are <strong>Unoptimised APK</strong>.</p>
  
  <p>In visual studio, I went to Android project options > Android Build.
  In release configuration, I checked <em>Generate one package (apk) per select ABI</em>. In the advanced tab, I checked the 4 supported ABI. Then I published and then uploaded 4 apks to google play console.</p>
  
  <p>It doesn't seem to be enough, the website advises me to:
  - Use the Android App Bundle to automatically optimise for device configurations (Not sure it is supported for xamarin solution)
  - or manage it yourself with multiple APKs (which I did with no success)</p>
  
  <p>I cannot ignore the warning, the button to go to next step is grayed.</p>
