Does Ionic support building different version of android target?


Now I think ionic requires android target-19 once running the command:
ionic platform add android
Is there a way that I can build a android platform with a higher android sdk version, such as android-21


I’d like to know as well.
You can go to platforms/android/ and edit AndroidManifest.xml and the properties files, but those get overwritten when you update the platform. Is there a better way?
