I've had an app in the playstore for a very long time, I don't have the code for my app as i lost it years ago, but have never had any problems editing and updating the app using apktool or sometimes apk editor, then resigning and uploading each update to playstore with the developer console.
My worry is google's ambition to eventually force everyone to upload only aab's (app bundles) rather than apks.
Is it possible to import my apk into the latest android studio and convert it to .aab bundle without the code?
If this is not possible, is there any other method to convert my .apk to .aab?
Any help is greatly appreciate, regards.
