Enhancing the experience of App Inventor developers with Google Play

Each operating system has its own "packages" that allow installing different applications to extend the features in the device. Android is not an exception, and their package type is the .apk file type (Android Application Package). This file has been present in Android since the very beginnings, allowing the development of several applications.
And App Inventor has the ability to build the app projects into those .apk files, as it is an Android app creator.

Google, as the owner of Android, always tries to optimize its environment by protecting the users and enhancing the development ecosystem, among other things. So, they wanted to make a change. In Google I/O 2018, Google introduced the .aab file format (Android App Bundle).
This new format is being used by Google Play Store, and Google is encouraging everyone to use it when distributing apps.

This project proposal intends to bring the option of exporting app projects in MIT App Inventor as .aab files, which make their distribution more straightforward in Google Play Store.
Moreover, if App Inventor had support for .aab files, it would be possible to make use of the App Signing by Google Play.
