How to reduce apk size build with crosswalk

Hi all. I have built apk with crosswalk, but the size of apk is about 20MB. Is there some tips to reduce apk size?

Unfortunately, since Crosswalk is basically a special, complete build of Chrome, it’s a large library weighing in at 28MB uncompressed for the Arm version.

If you use Crosswalk, there’s no way to make it smaller than that.

I heard that crosswalk-lite will reduce the size of compiled apk. But I have no idea how to integrated with ionic, do you have any experiences with this?
