Install android sdk api 21 maybe you have only 19

I have got Android SDK API 21 installed on my system and it is still giving these error messages. I think it has something to do with my Apache Ant installation. The reason why I come to this conclusion is because when I type the ant command into the command line it comes up with Buildfile: build.xml does not exist! Build failed error. Has this got something to do with it?

how version of node you use? if 0.12.X you need reinstall cordova complete

$ sudo npm -glf install cordova

The cordova version that I have got is 4.3.0. I don’t think it has anything to do with the cordova because when I add a platform to my project it works fine. It’s just when I run the ionic build android command it’s giving me the errors.
