Apps "The apk must be signed with the same certificates as the previous version"

[StevenHu]

I got the dreaded "The apk must be signed with the same certificates as the previous version" when uploading a new version of the app into Android Market. I successfully found a backup of the earlier keystore file (used by the first version), but how do I get the earlier key alias so they'll match up? Am I looking for the wrong key or in the wrong place?

Thanks

Hi when you first signed your app with the keystore when you update it you have to use that SAME keystore

Yes, I got it from backup.
