If I use the addJavascriptInterface like I was doing with the original
WebView, the index.html crashes when trying to call one of these
functions:
Uncaught TypeError: Object [object Object] has no method 'setProgress'
I guess evaluateJavascript is for the Java->Javascript sens like when
calling a javascript method from loadURL()?
I am passing a big object from Java to Javascript but asked by the second one.
Thank you.

Currently extension is not for xwalk core library.
We support addJavascriptInterface and evaluateJavascript in core
library. It would be great if you can share what errors you met.
Thanks.

Yes, I red it in Github but I've seen that is exactly the same. I
haven't tried it yet
because I am afraid it is not what I am looking for. With an
external API I guess I
won't be able to access my application variables, just Android
device functions.
Maybe I am wrong. And I definelly don't want to implement a network
connection between the two sides, e.g sockets).
Thanks for your time.
