app crashes after hacking cordova-plugin-crosswalk-webview to include crosswalk-lite

Question

I am trying to add crosswalk-lite to my cordova project using cordova-plugin-crosswalk-webview. I created a maven repos of https://download.01.org/crosswalk/releases/crosswalk-lite/android/canary/10.39.237.1/arm/crosswalk-webview-10.39.237.1-arm.zip on my github page, and modified xwalk.gradle pointing my maven. Building is OK, apk file size also looks as expected.

cordova plugin add https://github.com/Poordeveloper/cordova-plugin-crosswalk-webview

But app crashes with.
