Ionic4 with Crosswalk Webview on Android platform

DISCLAIMER: I’m aware crosswalk is not supported anymore, and that it adds substantial size to the APK

Now, since Ionic4 is not working in WebView versions <54 I’m trying to make current Ionic beta16 work with crosswalk. I was able to install and run everything with some workarounds, but can’t get icons to show. There’s no error in console. I can see valid network request for the icons and responses with something like this

<svg xmlns="" viewBox="0 0 512 512"><path d="M32 256c14.1..."/></g></svg>

But icons are not shown (there is blank space and sidemenu is working)
I’ve created gist with steps I did to make it work

Anyone got it working on Ionic4?

Have you solved this problem?
My app not show ionic icons with crosswalk.

Nope. Still have a problem. I think I will just make the minimum version 5.0 and whoever has 4.4 and less will get the PWA version, which works perfect on those devices if they have Chrome installed.

I finally managed to have it work with SVG icons showing.
I had to use a slightly modified version of the fetch workaround, found here:

But there was another problem, because requested URLs were something like:


but didn’t work (file not found), because of that triple slash at the beginning.
So I had to modify the workaround code such as:

        //remove triple slashes from the URL'GET', url.replace(/^file\:\/\/\//, 'file\:'), true);

There probably are more elegant solutions, but this is working for me with this ionic info:

On a device with Android 6.0.1 and WebView v44.

I don’t know what I changed, but now requested URLs are something like:


So I now have to use this instead:

        //remove triple slashes and prefix from the URL'GET', url.replace(/^file\:\/\/\/android_asset\/www\//, 'file\:'), true);
