I'm attempting to bundle Crosswalk with my Android application so that I can include its webview on a Fragment. The business case being that any HTML we want to run on the view will work across all android versions (the HTML could be a complex activity such as a game). I'm looking for an example which could manage this or how I could change my project to suit that purpose.
I've followed the tutorial here (https://crosswalk-project.org/documentation/android/embedding_crosswalk.html) to get started, this allows me to build an APK that correctly shows web content on my Samsung S4, which uses the ARM chipset, however I now also would like to cover x86. I've got an emulator to test with but I'm not having much luck. I've also attempted to follow the steps here (How to add crosswalk webview in my own android library module?).
I've tried the following:
- Different permutations of the including the modules provided on their download page.
- Including both the ARM and x86 libraries (Android Studio complains that the classes are defined twice which is what I would expect).
- Copying the 'x86' from src/main/jniLibs from within the x86 module and pasting it into the arm module which my application references.
- Using 'XWalkActivity' (https://crosswalk-project.org/apis/embeddingapidocs_v7/index.html) not only did this not work on x86 but also stopped working on my ARM device.
The closest I've got is the code at the bottom of this post which allows me to install the application on my emulator but does not load the web content.
Few key things to note from my stack track (at the end of this question).

This looks problematic however this also occurs when I run it on my ARM device and that works as expected. Does anyone know what these are and the implications?

This looks like the set up that XWalk goes through, note that 'XWalk core architecture matched'; I would read from this that it has the native libraries it needs so perhaps something else is the issue?
