[Q] Replacing .png resources

pandaweb said:

I am trying to create a module which replaces the stock Google Hangouts emoticons.

The problem I am facing is the Xposed log gives me a resource not found exception. So it's not replacing the image because it can't find it.
The emoticon resources have odd names, perhaps there is some obfuscation going on? Or maybe I'm just doing something wrong or missing something.

I started off trying to just change the icon of Hangouts, it's called ic_launcher_babel.png, but I had no luck with that either.

Here are my sources: https://github.com/bbbenji/HangoutsReplacer[1]

Here is a compiled .apk: https://github.com/bbbenji/HangoutsReplacer/blob/master/com.benji.hangoutsreplacer.apk[2]

Great, that fixed the resource not found exception. But it's not replacing the actual resource. There are no errors, but no result. Do you, alirazeen, or anyone else have an idea what's going on?

Replacing Drawables works similar. However, you can't just use a Drawable as replacement because this might result in the same instance of the Drawable being referenced by different ImageViews. Therefore, you need to use a wrapper:

resparam.res.setReplacement("com.android.systemui", "drawable", "status_bar_background", new XResources.DrawableLoader() {
    @Override
    public Drawable newDrawable(XResources res, int id) throws Throwable {
        return new ColorDrawable(Color.WHITE);
    }
});
