Issue when publishing app to Google Play Console

Question

Friends would like a help, I am publishing for the first time an app in the play store, I created the app running perfectly, I already have a Google play console account, I created the app but when I will upload the signed APK to the production I get the following warning and can’t continue:

APK not optimized

Warning:

This APK includes unused features and codes that are sent to users. Your app would be smaller if you used the Android App Bundle. When the app is not optimized for device settings, the size of the download and installation is larger than necessary. Larger apps have lower installation rates and take up space on users' devices.

Resolution:

In order to automatically optimize the app for multiple device settings, use the Android App Bundle or create multiple Apks.

Can anyone tell me how to solve this issue I’ve tried everything.

From 08/2021 the Play Store will require new apps to be published using the AAB format (Android App Bundle)

RELEASE TYPE	PREVIOUS	REQUESTED ON 08/2021
New APP	APK Target API level 29+	AAB Target API level 30+
App update	No Format Change Required Target API level 29+	No Format Change Required Target API level 30+

That doesn’t strike me as a problem and just a warning.

Google Play is showing this message more to inform that there is a new method to generate the application (app-Bundle), informing that this new method is more efficient than generating an APK and etc. This does not mean that your application is in trouble.

It may be that in the future they choose not to accept more Apks uploads, but still not the case.

To create a app-Bundle just you are in an android-studio that has this option and the process (for what I tested) looks the same as generating an APK.

In the menu bar of android-studio click on Build → Generate Signed Bundle / APK
_{This window will open}

Select the Android App Bundle and click on Next, from this point the process is the same as generate a signed APK, except at the end that in this new method you do not have to select the 'Signature versions', this will generate a file .Aab.

Note: Until the moment I haven’t sent any application using this method so I don’t know what problems might occur after this point.
