I am currently having trouble with a live wallpaper that does some very intensive drawing. However , upon testing my code I find the wallpaper is laggy and is destroyed when the screen gets rotated.
Within my draw method I have this :
mRectArray = new Rect[] {
new Rect(0, 0, c.getWidth(),
(c.getHeight() + statusBarHeight) / 20),
new Rect(0, (c.getHeight() + statusBarHeight) / 20,
c.getWidth(),
(c.getHeight() + statusBarHeight) / 20 * 2),
new Rect(0, (c.getHeight() + statusBarHeight) / 20 * 2,
c.getWidth(),
(c.getHeight() + statusBarHeight) / 20 * 3),
new Rect(0, (c.getHeight() + statusBarHeight) / 20 * 3,
c.getWidth(),
(c.getHeight() + statusBarHeight) / 20 * 4),
new Rect(0, (c.getHeight() + statusBarHeight) / 20 * 4,
c.getWidth(),
(c.getHeight() + statusBarHeight) / 20 * 5),
new Rect(0, (c.getHeight() + statusBarHeight) / 20 * 5,
c.getWidth(),
(c.getHeight() + statusBarHeight) / 20 * 6),
new Rect(0, (c.getHeight() + statusBarHeight) / 20 * 6,
c.getWidth(),
(c.getHeight() + statusBarHeight) / 20 * 7),
new Rect(0, (c.getHeight() + statusBarHeight) / 20 * 7,
c.getWidth(),
(c.getHeight() + statusBarHeight) / 20 * 8),

That’s 40 rectangle constantly being initialized onDraw.
Now, the problem is these rectangles must be constantly initialized as i’m animating the right side of 20 of the rectangles…
I have another 40 or so if statements for animating the rectangles..
How can I condense my code so that performance isn’t sacrificed??
initialize your array in onSurfaceChange() by using height and width of onSurfaceChange() function.
