As for free development (what fees) ? Can't understand what do you mean ?
I also not clear with this requirements.
My understanding is for us to publish to Play store, we are required to register for a developer account by paying US$25 for lifetime.
Meanwhile, to enable us to become developer in Apple developer account, even we don't want to publish an app on Appstore, we still need to pay US$99 annually for the registration and to generate the certificate and provisional profile.
So I guess the new rules would be similar to Apple, Google may charge Android developers at certain amount, which may be need to renew annually.
The new fee is different from the fee for Play store developer console.
edit: You may need to pay additional fees if you are publishing your apps on
other Android store such as F-Droid.
For now, indie developers or students can develop any apps and share among their friends without registering for a developer account.
Anyone can start developing anytime and build an APK for Free!
This is going to be changed starting September 2026!
