I lost my .keystore file?

Question

Ok folks.. long story short, I was developing on a computer that I no longer have access to. I was able to retrieve the source code, but not the .keystore file used to sign

Answer 1

From long days, I also search a solution for that, but not successfully till now. If you have the last version of your app apk, then you can retrieve certificates from that by using the jarsigner cmd command. But you need a private key for update. Google Play did not provide any relaxation for that.
