Have you changed the version name also. make sure you had done that and again try to sign the app using the same keystore and password. the problem will get solved. also make sure you have the same base package name and before.

It sounds like you uploaded a debug build, rather than a release build.

I am totally agree with @Sean Owen answer that you may have tried to upload the debug build.

Still, let me provide you additional information if you forgot to prepare release build and yes dont forget to sign this APK with the same keystore that you have signed with previously.
