Play Store Multiple APKs

Recently I needed to do an upgrade to an Android app I had released, Baby Feed, from version 1.0 to 1.1. When I uploaded the new APK to the Play Store I ran into problems:

The error message:

This configuration cannot be published for the following reason(s): Version1 is not served to any device configuration: all devices that might receive version 1 would receive one of version 2. Some devices are eligible to run multiple APKs. In such a scenario, the device will receive the APK with the higher version code.

I took me some time to understand what it meant. You need to archive the old APK before the new one is ok.
