Display images on Android widgets using html & TextView

Question

I am trying to dynamically display images on a home screen widget. Since RemoveViews offer a very limited set of methods for interacting with the layout, I'm trying to use HTML to get the same effect. Regular HTML displays are ok ( <u>,<b>etc.), however I cannot display images. Instead, I get a small empty square in the TextView.

eg.

s = "<b>Hello</b> <img src='world'/>";
ImageGetter imgGetter = new ImageGetter(context);
RemoteViews views = new RemoteViews(context.getPackageName(), R.layout.widget);
views.setTextViewText(R.id.textarea, Html.fromHtml(s, imgGetter, null));

The getter image is as follows:

public class ImageGetter implements Html.ImageGetter
{
    Context c;

    public ImageGetter(Context c)
    {
        this.c = c;
    }
    public Drawable getDrawable(String source) {
        Drawable d = null;
        int resID = c.getResources().getIdentifier(source, "drawable", c.getPackageName());

        d = c.getApplicationContext().getResources().getDrawable(resID);
        d.setBounds(0, 0, d.getIntrinsicWidth(), d.getIntrinsicHeight());

        return d;
    }
}

The code works fine if I use the usual action. I suspect this is an error / undocumented android function when used with AppWidgetProvider. I just need confirmation.
