CrossWalk Webview not launching URL

Question

I am using Cordova CrossWebViewEngine and creating XWalkCordovaView to launch my app in webview. But it is throwing an error saying

Here is my code about launching the app

 CordovaWebViewEngine cordovawebviewEngine = super.makeWebViewEngine();
 XWalkWebViewEngine xwe = (XWalkWebViewEngine) cordovawebviewEngine;
 XWalkCordovaView swv = (XWalkCordovaView) xwe.getView();        
 swv.load(launchUrl,null);

Has anyone faced similar error or issue with Cordova Cross-Walk?

Edit: I tried changing my code to get XWalkView

xWalkWebView = new XWalkView(this.getApplicationContext(), this);
xWalkWebView.load(launchUrl, null);

I still get the same exception java.lang.UnsupportedOperationException

Update - 02/09/2016 I changed my main activity to extend XWalkActivity and now I have to implement a method onXWalkReady - the code looks like below

@Override
protected void onXWalkReady() {
  xWalkWebView.load(launcUrl, null);
}

I don't get the same error as I mentioned in the main question, but I get following errors

Error while loading asset assets/icudtl.dat: java.io.FileNotFoundException: assets/icudtl.dat 

glUtilsParamSize: unknow param

Fatal signal 11 (SIGSEGV)

Did you try fixing the issue by adding the user agent as stated here : http://stackoverflow.com/questions/32199128/change-the-user-agent-of-crosswalk-13-as-webview-in-cordova/32925922#32925922 ? — Zakaria, Feb 01 '16 at 20:47
Otherwise, can you please paste a more complete stacktrace ? — Zakaria, Feb 01 '16 at 20:49
I am not sure if this is a user-agent issue as this is saying about not identifying method load. — yogsma, Feb 01 '16 at 20:55
I've found [this Jira issue](https://crosswalk-project.org/jira/browse/XWALK-4938). Apparently that exception is thrown if you try to call some operations before XWalk is ready. Not sure about load though, never integrated Cordova with XWalk yet. — Mister Smith, Feb 05 '16 at 23:23
@ρяσѕρєяK - error is coming from where I am trying to load the URL. — yogsma, Feb 08 '16 at 14:12
