Hello,
I want to replace Webview with Xwalkview.
I've followed the tutorial at:
https://crosswalk-project.org/documentation/embedding_crosswalk.html
I am using Android Studio, so to add XWalk to my project I inluded both
.jar files as libraries.
There are no compilation errors, but when I try to run it it says:
The following classes could not be instantiated - org.xwalk.core.xwalkview
java.lang.NullPointerException
