Trying to make it work under Crosswalk webview

[renandecarlo]

I have little knowledge to native Java itself. I'm trying to make this plugin work with Cordova + Crosswalk, can you help me out? I think it's a 1-2 line thing, but I've no idea where could it be.

It also doesn't work for me with Ionic (which uses Crosswalk). I am not sure if the issue is due to Crosswalk though.

I've contacted this plugin's developer, and it seems he couldn't get Crosswalk to work under his Linux machine. I think he was trying to use Crosswalk itself, instead of Crosswalk for Cordova.

Anyway, I found this plugin which does similar to Cordova, but it works with Cordova plugins. Haven't tested it yet, but it's worth a shot: http://plugins.cordova.io/#/package/com.ludei.webview.plus

Let me know if you have any update.

@renandecarlo Thank you for the reply. That looks like a great plugin, but I will continue to use Crosswalk with Ionic. I will keep you updated if I get this plugin to work, or if I create my own.

Did you get it to work @Shilo?

@renandecarlo Sorry, no updates. I haven't had a need to implement this feature, so I haven't done any future testing.

I also believe I was wrong in my previous post. I don't think Ionic uses Crosswalk by default unless I enable it, since the feature is still in beta. So maybe the problem isn't linked to Crosswalk, in my case.

[renandecarlo]

Right, thanks.

Any updates?

To detect and process volume button presses, I use this code in MainActivity.java:

import android.view.KeyEvent;

    @Override
    public boolean onKeyDown(int keyCode, KeyEvent event) {

        if (keyCode == KeyEvent.KEYCODE_VOLUME_DOWN) {
            this.loadUrl("javascript:cordova.fireDocumentEvent('volumedownbutton');");
            return true;
        } else if (keyCode == KeyEvent.KEYCODE_VOLUME_UP) {
            this.loadUrl("javascript:cordova.fireDocumentEvent('volumeupbutton');");
            return true;
        }
    }

Then I listen for volume button presses with this Javascript code:

document.addEventListener("volumeupbutton", function (e) {e.preventDefault(); volButtonUp();}, false);  
document.addEventListener("volumedownbutton", function (e) {e.preventDefault(); volButtonDown();}, false);

This also works with Crosswalk perfectly. :-)
