When exporting what is the app version code, minimum android version, domain access and target android version and what should they be?
App version code is another way to express the App version; an arbitrary number that you should increase by 1 or more each time you want to publish.
Minimum android version represents the minimum Android API level you want to support (normally leave it)

I don't change Domain access but the tooltip in the XDK gives you some info (leave it)
Target android version is the android version that you mainly support (normally leave it)
