Cordova version: 4.3.0
java version \"1.8.0_40\" 64bit
OS X 10.10.2
Ant version: 1.9.4
Your Cordova is too high to work with Android Api 19. Meaning it's newer so it references libraries that Api 19 doesn't have and gives an error. So you need to dumb it down a little bit.
Uninstall it:
sudo npm uninstall -g cordova
And then install an older version of cordova that works well with Api 19:
sudo npm install -g cordova@4.0.0
and now do everything again from scratch. "cordova create blabla", "cordova platform add android", "cordova run android", etc.
To get a list of cordova versions do:
npm view cordova versions
But I know that 4.0.0 will work with Api 19 since I had the same problem.
