After adding Crosswalk .apk filesize remains the same. Is this normal?

Hello,

Followed the steps to add Crosswalk to a new project and everything seemed to be Ok. No errors, everything fine. However after running ionic build android --release the ant-build folder holds a MainActivity-release.apk the same size as before adding Crosswalk.

Is this normal? I was expecting something in the 12-15Mb range. Installed App on 4.0 tablet and it performs perfect. Cannot connect to Chrome and check that way, is cheap tablet and there are no drivers available.

Thank you, your help will be appreciated.
