Ionic Framework start error on Android

I have a project with Ionic working fine in iOS (emulator and device), web and with a problem in Android.

I have used to create the project:

ionic platform add android

I open the project with Eclipse, everything is Ok, no errors, and CordovaLib is loading fine.

When I try to deploy in my device, I have this error:
