oh. I forgot to mention the critical step 10.

1. Cross your fingers, find your lucky charm and hold it close to your left ear then turn around clockwise three times. With your eyes still closed, reverently face your computer and chant (softly): “oh mighty machine”. Bowing down to the computer is optional. Then run cordova build android
