Question

How can I use two canvas in my application so that I am able to rotate two bitmap images with different rotation speed

Answer 1

Why don’t you just use the same canvas?

c.save();
c.rotate(rotationAngleForBitmap1);
c.drawBitmap(bitmap, matrix, paint);
c.restore();
c.rotate(rotationAngleForBitmap2);
c.drawBitmap(bitmap2, matrix, paint)
c.restore();
