Crosswalk and $http doesnt work

Just started working on adding Android support to my app and ran into this problem, but I can’t seem to get your workaround to work. Am I doing this right?

In the file

engine/cordova-crosswalk-engine-c0.7.1/src/android/XWalkCordovaResourceClient.java

I am commenting line 204, which looks like this:

return new WebResourceResponse("text/plain", "UTF-8", null);

Next I run

ionic build android

and finally I run the app on the device

ionic run android

The $http request still fails with a 404 – am I missing a step? Thanks!
