Pixel-Perfect Collision Detection Android

I have based my code on Mayra’s example and made bitmap pixel collision handling. I hope this will help.

public class CollisionUtil {
    public static boolean isCollisionDetected(Sprite sprite1, Sprite sprite2){
        Rect bounds1 = sprite1.getBounds();
        Rect bounds2 = sprite2.getBounds();

        if( Rect.intersects(bounds1, bounds2) ){
            Rect collisionBounds = getCollisionBounds(bounds1, bounds2);
            for (int i = collisionBounds.left; i < collisionBounds.right; i++) {
                for (int j = collisionBounds.top; j < collisionBounds.bottom; j++) {
                    int sprite1Pixel = getBitmapPixel(sprite1, i, j);
                    int sprite2Pixel = getBitmapPixel(sprite2, i, j); 
                    if( isFilled(sprite1Pixel) && isFilled(sprite2Pixel)) {
                        return true;
                    }
                }
            }
        }
        return false;
    }

    private static int getBitmapPixel(Sprite sprite, int i, int j) {
        return sprite.getBitmap().getPixel(i-(int)sprite.getX(), j-(int)sprite.getY());
    }

    private static Rect getCollisionBounds(Rect rect1, Rect rect2) {
        int left = (int) Math.max(rect1.left, rect2.left);
        int top = (int) Math.max(rect1.top, rect2.top);
        int right = (int) Math.min(rect1.right, rect2.right);
        int bottom = (int) Math.min(rect1.bottom, rect2.bottom);
        return new Rect(left, top, right, bottom);
    }

    private static boolean isFilled(int pixel) {
        return pixel != Color.TRANSPARENT;
    }
}
