Tried building an Android app with PhoneGap / Cordova. It just kept failing and failing. The issue turned out to be in naming. I named the bundle/widget id as : com.cordova.Test0205 … Failed each time I built.
Then deleted that project and created a new one naming it as : com.cordova.Test
It worked like a charm. So there you go. No numbers in your ID.
