As we careen toward a future in which Google has final say over what apps you can run, the company has sought to assuage the community's fears with a blog post and a casual "backstage" video. Google has said again and again since announcing the change that sideloading isn't going anywhere, but it's definitely not going to be as easy. The new information confirms app installs will be more reliant on the cloud, and devs can expect new fees, but there will be an escape hatch for hobbyists.
Confirming app verification status will be the job of a new system component called the Android Developer Verifier, which will be rolled out to devices in the next major release of Android 16. Google explains that phones must ensure each app has a package name and signing keys that have been registered with Google at the time of installation. This process may break the popular FOSS storefront F-Droid.
It would be impossible for your phone to carry a database of all verified apps, so this process may require Internet access. Google plans to have a local cache of the most common sideloaded apps on devices, but for anything else, an Internet connection is required. Google suggests alternative app stores will be able to use a pre-auth token to bypass network calls, but it's still deciding how that will work.
The financial arrangement has been murky since the initial announcement, but it's getting clearer. Even though Google's largely automated verification process has been described as simple, it's still going to cost developers money. The verification process will mirror the current Google Play registration fee of $25, which Google claims will go to cover administrative costs.
So anyone wishing to distribute an app on Android outside of Google's ecosystem has to pay Google to do so. What if you don't need to distribute apps widely? This is the one piece of good news as developer verification takes shape. Google will let hobbyists and students sign up with only an email for a lesser tier of verification. This won't cost anything, but there will be an unclear limit on how many times these apps can be installed. The team in the video strongly encourages everyone to go through the full verification process (and pay Google for the privilege). We've asked Google for more specifics here.
