Hi I am trying to find the number of rectangles per sec in three
different size rectangles. I did find it though. But the only problem
is that I see all the rectangles after it ran the program completely.
But I would like to have rectangles drawn, when I call
canvas.drawRect(rec1,paint); function.
I am also looking to keep the old rectangles on the screen while new
ones are drawn.
I tried with lots of different options nothing worked. To display the
rectangles
Can anybody show me the direction to which way to go ?
Thanks in advance.
Cheers
Kishore Srimat
