Hi, I thought about subclassing Drawable. But I can't seem to find a way to initiate a Drawable by itself e.g. Drawable newDrawable = new Drawable(); even thought Drawable() is mentioned as a constructor.
I have only seem getDrawable() as a method in ImageView. How do I just create a Drawable after I subclass it? Eclipse isn't giving me meaningful error message to proceed. Just an 'X' .
