I've verfied this myself. the activity doesn't have any content to start on.
Amend your config.xml file with the following
you can add it after <author>
(if this is amended after the cordova project is built, and added to the xml file within 'app' then it should be <content src="index.html" /> )
Ashley this is easiest to quickly verify in Android Studio, where you also see the java error code and that it refers to the xml parser where the starting url can't be fetched.
