android how to find gesture overlay is fully filled
<p>I am learning android gesture overlay and I was struggled in implementing some logic. The logic I want to implement is, 
I will show a gesture overlay like a square, The user started painting the gesture overlay with some color, I need to find if the overlay is <strong>fully 100% painted</strong>. If it was fully painted then i need to go for some other flow.Anybody please help how can we implement that logic... Many more thanks in advance.</p>
