Answer 1

You can do the following, to get the volume button running with android:

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

    //If volumedown 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;
}

@Override
public boolean onKeyUp(int keyCode, KeyEvent event) {
    LOG.d(TAG, "KeyUp has been triggered on the view" + keyCode);
    // If back key
    if (keyCode == KeyEvent.KEYCODE_BACK) {
        this.loadUrl("javascript:cordova.fireDocumentEvent('backbutton');");
        return true;
    }
    // Legacy
    else if (keyCode == KeyEvent.KEYCODE_MENU) {
        this.loadUrl("javascript:cordova.fireDocumentEvent('menubutton');");
        return true;
    }
    // If search key
    else if (keyCode == KeyEvent.KEYCODE_SEARCH) {
        this.loadUrl("javascript:cordova.fireDocumentEvent('searchbutton');");
        return true;
    }
    return false;
}

I copied this code from a cordova bug report. This code is valid for cordova 2.0. I thin you'll have to change "cordova.fireDocumentEvent" to "phonegap.fireDocument" or "PhoneGap.fireDocumentEvent"

update: Just wrote a small blog-post about the bug, that was solved by the code above. The link to the Cordova-Issue-Tracker can be found in that post: http://christian-kuetbach.de/blog/post/13

update 2: The Issue seems to be fixed within cordova 1.9: https://issues.apache.org/jira/browse/CB-871

Hope this helps.
