The apk must be signed with the same certificates even if old one is not correct

Question

Hy, yesterday, I publish an app on play store. I have done a big mistake, I signed the app with debug.keystore so the map is not shown when the app is published.

to solve this, I resign the app with a new keystore and generate a new map key (with new sh1). but the problem that i can't now publish the new apk, they said (The apk must be signed with the same certificates).

what I can do now ?

You have to use the same certificate when you update your apk or Google Play won't recognize it as the same app.

From Google documentation

Application upgrade – As you release updates to your application, you must continue to sign the updates with the same certificate or set of certificates, if you want users to be able to upgrade seamlessly to the new version. When the system is installing an update to an application, it compares the certificate(s) in the new version with those in the existing version. If the certificates match exactly, including both the certificate data and order, then the system allows the update. If you sign the new version without using matching certificates, you must also assign a different package name to the application — in this case, the user installs the new version as a completely new application.

Just as important as the manifest package name is the certificate that application is signed with. The signing certificate represents the author of the application. If you change the certificate an application is signed with, it is now a different application because it comes from a different author. This different application can't be uploaded to Market as an update to the original application, nor can it be installed onto a device as an update.

In conclusion: There are some parts of your application that can not change. Please be careful.

So I'm afraid you can't do much in this case.
