Moodle for mobile

Hi

I am trying to customise the moodle app.

Please advise me as to what I am doing wrong, I have done the following

1. on Github I Forked "moodlehq/moodlemobile2"
   
2. I then edited config.xml (here I edited the following tags)
   • <widget id>
   • <name>
   • <description>
   • <author>
3. I then edited config.json (here I edited )
   • "app_id"
   • "appname"
     
4. Next I rebranded all the icons and splash images
5. I then used PhoneGap to generate the rebranded app from Github

The problem is this: I then installed the app but when I try to open it all I get is a White screen and nothing happens.
