Android Question At final review Non-upgradeable APK

[wstein25]

I have uploaded a revised apk to the Playstore, and am about to release. At final review I get this warning from Google:

Non-upgradable APK
Warning:

None of the users of this APK will be able to upgrade to any of the new APKs added in this release.

Tip:

Ensure that all your new APKs are added to this release.

I am clueless what this exactly means, and how to repair it.

Thanks

Have you defined your app version code correctly, did you increase your version number?

MAJOR.MINOR.PATCH or something like that.

For example:
#VersionCode = 1
#VersionName = 1.0.1 or 1.0.0.1 to 1.0.2 or 1.0.0.2
