GOOGLE IS DITCHING THE APK FORMAT

 

while APK's are still supported for the older apps but the newer applications have to stick to AAB(Android App Bundle).Google officially announced the decision to switch to AABs today,

Starting August this year, all apps will be required to submitted in the newer AAB format. First introduced in 2018, the AAB format is set to bring smaller file sizes to new apps and make other aspects easier to control.

Many app on google play are already using the newer format.That's a good new's for the user's as well as developer's because ABB has smaller file size compared to APK (-15% approx) , developer will get more flexibility over their app, Hence the app efficiency and update's will get much faster.
