hi please i need to know is it possible to create android app bundle using app inventor ? or app inventor source ?
i like the idea of smaller size with the same functions
No this isn't currently possible.
App Inventor 2 apps cannot use or create the Android App Bundle to ‘optimize’ your app. You have to do that yourself by re-using components etc. If you want to create an App Bundle, code use the professional Android Studio. AI2 apps are as optimized as can be as they are compiled provided the developer uses small sized images, sound files etc in their app.
Please read the articles in the Forum to learn the details about how to handle issues using AI2:
