Recover a deleted key.

[Jacques_C_]

Hello ! (I apologize in advance but I do not speak English and my text is translated with google translation)

I wanted to get an update from my Android application unless an error message saying that I do not have the same digital fingerprint that the latest version.
I know why, it's because I changed intel xdk account.
So I picked up the old account but I remember you remove the key with which I compiled the project.
Is there a way to retrieve a deleted key?

You could recover a password from a Keystore:

But you can´t recover the Keystore

The documentation says:

 You must keep your keystore in a safe and secure place.

I´m sorry you need to create another keystore and upload to the Playstore another application signed with this new keystore.
