Android Studio, file loss . jks

Question

I lost the app’s . jks file and now I can’t update the app in the play store. What I can do in this case?

Answer 1

Unfortunately you can no longer update the application. I suggest next time put the Keystore in some version control.

Warning: Keep your Keystore and private key in a safe and Secure place, and ensure that you have Secure backups of them. If you Publish an app to Google Play and then lose the key with which you Signed your app, you will not be Able to Publish any updates to your app, Since you must Always Sign all versions of your app with the same key.

Answer 2

Updated answer: You can contact Google support to resolve this.

Behold "Reset a lost or compromised private upload key":

If you lose your private upload key or it is compromised, create a new one and contact the Google Support team Play for redefine.

Observing: the upload key reset will not affect the upload key subscription to the app used by Google Play to re-sign Apks before sending content to users.

The process boils down to:

1. Create a new key (see here)
2. The account owner must contact Google via a form (here), attaching the file .pem generated.
3. Wait for the return of the support team via email.
