Lost your android app key?

Question

Google Play

Hello everyone, once upon a time I started making an application, published it and everything was ok. Then I gave up on its development, changed more than one computer and OS, and decided to start developing my application again, only on a different stack, I did everything, but when I upload a new version to google play, it gives an error:

The APK files added earlier are signed with certificates with fingerprints
, and the new APK file with certificates with fingerprints.

Is it possible to do something, given that I have lost all the old keys?

Answer 1

Write to google support, send them a new generated key and in a couple of days you will be able to publish an application signed with a new key.
