Speeding Up Bitmap Animation

Question

I'm making a game, while a friend of mine is designing all the graphics. All graphics are PNG files, and drawn and animated using Bitmaps and Canvas in SurfaceView.

One piece of animation involves the main character moving around during the menu, which uses 35 large PNG files. It's too big to have it all loaded in memory, and loading each file when needed is too slow for what he wants. So, what can I do to make this work?

OPTIONS THAT DON'T WORK

Making the image smaller. Making the image smaller than what he wanted won't fly. Anything less than original quality won't fly either.

OPTIONS WE'RE LOOKING INTO

Making the animation a video. However, I don't know how to take a video and turn it into an interface.

My code:

Matrix matrix = new Matrix();
matrix.postScale(scaleFactorX, scaleFactorY);

penguin = BitmapFactory.decodeResource(getResources(), R.drawable.fish_01);
penguin = Bitmap.createBitmap(penguin, 0, 0, penguin.getWidth(), penguin.getHeight(), matrix, true);

canvas.drawBitmap(penguin, canvasWidth - penguin.getWidth(), canvasHeight*0.02f, null);

have you tried using the png as an asset? using /res/ wastes more resources iirc... also are you loading each picture at a time, or are you using an atlas? — Dix, Mar 15 '12 at 22:04
If you're not using full 32 bit colors (ARGB) there is an option to use a lower color depth, this will decrease the memory usage by a good factor. — Dan S, Mar 15 '12 at 22:07
@Dix As an asset? An Atlas? I haven't heard of that before. Can you explain further? — Jesse Jashinsky, Mar 15 '12 at 23:14
Checkout the RGB_565 configuration of [Bitmap.Config](http://developer.android.com/reference/android/graphics/Bitmap.Config.html) — Dan S, Mar 15 '12 at 23:26
@Dan It says it only stores RGB information, no A. Without transparency the background will be overwritten. — Jesse Jashinsky, Mar 16 '12 at 00:52
google 'texture atlas', and by an asset I mean by loading the picture from the /assets/ folder — Dix, Mar 16 '12 at 11:42
1. Texture atlas, if I understand correctly, doesn't apply to this. 2. I'll try asset instead of res to see if it makes a difference. — Jesse Jashinsky, Mar 16 '12 at 19:19
