You can now build "embedded" Crosswalk 14 apps with the Intel_XDK for Chrome 43 webviews on Android 4.x and higher devices. See Why Use Crosswalk? for why Crosswalk matters on Android devices.
You select Crosswalk 14 by selecting the pulldown in the Build Settings section of the Projects tab. This version is only selectable by using version 2170 or greater of the Intel XDK.
