After much digging, i believe that this problem is related to me not having any platforms added for phonegap to build from. This is missing from their documentation.

For some reason, you can't add platforms in an obvious way so i found this:
You need to add platform to work with, whilst the documentation is so very very poor:
Command
phonegap build android
build
C:\var\www\sexdiaries.co.uk\sexdiaries>phonegap build android
[phonegap] detecting Android SDK environment...
[phonegap] using the local environment
[phonegap] adding the Android platform...
[warning] missing library cordova/android/3.0.0
[phonegap] downloading https://git-wip-us.apache.org/repos/asf?p=cordova-android.git;a=snapshot;h=3.0.0;sf=tgz...
[phonegap] compiling Android...
[phonegap] successfully compiled Android app
Then you are good to go, doing an import with Andriod Studio will also work now as you have a project to work with :)
Fantastic.
