Answer 1

Use the below code to get the key event

Use this code in your existing java class

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

    //If volume down key
    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;
    } else {
        //return super.onKeyDown(keyCode, event); 
    }
    //return super.onKeyDown(keyCode, event);

    return true;
}

and using this below in your html page

document.addEventListener("volumeupbutton", onVolumeUpKeyDown, false);  

document.addEventListener("volumedownbutton", volumedownbutton, false);

function    onVolumeUpKeyDown()
{
    alert("Working Up")     
}

function    volumedownbutton()
{
    alert("Working Down")       
}
