How to optimize an application for the Google Play market?

Question

Android

hello i have this problem created android apps on this site ai2.appinventor.mit.edu but when i publish it in developer's google play account it gives warning:
Unoptimized apk file
Warning
This apk file contains unused resources and code that get to users. You can reduce the app size with the Android App Bundle. Because you haven't optimized the app for different device configurations, users have to download and install more data. Large apps take up a lot of space on devices and users install them less frequently.
Decision
Use the Android App Bundle to automatically optimize your app for different device configurations, or manage optimization yourself with multiple APK files.

Help me solve this problem please

Answer 1

Wait for the website builder to start optimizing itself.
Or master Android Studio and make an application there yourself.

Answer 2

Instead of apk, it says that you need to download .aab
But whether the application generator you use to create them is a big question.
