Google Finally Decides To Make Sideloading Android Apps Easier And Safer With File Signature Checks
So this is how it works. Google will modify the header file of the APK and add a new metadata field that will house the app’s file signature.

In countries like China where the Google PlayStore is banned, users can perhaps sideload the apps (not sure if the apps can be verified via Google Servers)....
