Then you'll have to make friends with the Chromium browser bundled with your game. This is the most efficient way of running HTML5 code as an app. I don't think that either of the options we listed in this topic will free your from that additional size. In 2016 that +20-30MB shouldn't be a problem. And if you target Android 5+ then the WebView is already on the phones, so your apps can be smaller.
I built my games without Crosswalk and got a 3.5 mb APK. 12 mb when installed. However I did notice very long load time opening the games.
What is "Webview?" the default browser I have on my CAPX file is Chrome. Should I switch to Default?
