I have been searching for many hours and cant find a reason for this
so I thought I would put it to the list. I am creating a custom view
which I am planning on animating. Here is what I do based on the
pattern shown by LabelView example in the API demos.
What I am expecting is to log the value "23,56 34,45 39,23" to be
printed when the shape initializes but instead the value s is NULL. I
thought I followed the example exactly. I am using r8 of the API.
Any help or pointers appreciated.

private Paint mStrokePaint = new Paint(Paint.ANTI_ALIAS_FLAG);
public MyShapeDrawable(Shape s) {
super(s);
mStrokePaint.setStyle(Paint.Style.STROKE);
//006837
mStrokePaint.setARGB(0xFF, 0x00, 0x68, 0x37);
}
public Paint getStrokePaint() {
return mStrokePaint;
}
@Override protected void onDraw(Shape s, Canvas c, Paint p) {
//006837
s.draw(c, p);
s.draw(c, mStrokePaint);

this.setText(s);
