What can I do if i lost the keystore i used to sign my application?

Solution. No you cannot update your program if you lost your keystore.To help your users find your new app and continue to get updates ....

Leave the application published. Publish the same app, with new package name and new key. Change the text for the older app explaining that the new app is called XYZ etc, that this version will not be updated anymore. Put a better backup plan into action :-)

Go to your backups to get the keystore back.

You can not update an app without the correct signature. That is for your protection and your users protection.

The apk must be signed with the same certificates as the previous version problem and solutions.
