custom site URL, resource images not working using phonegap develop instructions

Hi,

I built the app using the directions found here.  I have been working on this for days.  

I have a few problems.

1. I built the app using the directions in the slideshow.  my custom url does not work.  i followed the directions to add the line: and change the url to my moodle site url.

onEnter: function($state) {

       $state.go('mm_login.credentials', {siteurl: 'http://mymoodle.com'});

   }

})

however, when opening the built app.  the app defaults to the page asking me to put in my site url.  just as if i haven't made any changes.  I want to skip that page so users would just need to put in their account info to get in.

2. I have also done the directions on how to change all images to my own.  i used ionic resources and resized my images for all devices.  My splash and icon images show.  but they are not resized.  they all appear in the same size on all devices.  thus making the images cut off on the smaller devices.  it is as if the app is not using the custom made images.

3. I have made a working mobile.css file for css changes.  but would really like to have the colors also change on the login screen.  where it asks for credentials to login.  this is in the moodle default color.  where would I make changes to that color?

suggestions?
