Most of the PhoneGap configuration is setup for you when Lianja generates the files needed for PhoneGap Build.

If you need to customize the config.xml for PhoneGap above and beyond what can be done through the UI you can do so.

When code generating for PhoneGap and packaging up the PhoneGap files into a zip file that is uploaded to the PhoneGap Build Service for you, Lianja uses "template" files that can be customized if required.

These template files reside in:

c:\lianja\mobileapps\templates\android\phone
c:\lianja\mobileapps\templates\android\tablet
and
c:\lianja\mobileapps\templates\ios\phone
c:\lianja\mobileapps\templates\ios\tablet
