Question

I am drawing a frame by frame animation to a canvas and I have about 100 pics that I’m using to do this (which is about 1.5MB total). I started out by just doing this:

s000 = BitmapFactory.decodeResource(getResources(), R.drawable.s0);
s001 = BitmapFactory.decodeResource(getResources(), R.drawable.s1); ...etc...

to every image and then drawing each image to the canvas:

c.drawBitmap(s000, X, Y, null);

to make an animation.

The problem is that I get this error “OutOfMemoryError: bitmap size exceeds VM budget”. How would I load all the pics without getting this error? Is 1.5MB to much memory or do I have a memory leak? What would I do to fix the memory leak?

Thank you very much for your help. I am noob with android so could you please leave examples and not just tell me to do something that I wont understand 🙂 Thanks again

Answer 1

Try like this for every frame you draw:

s000 = BitmapFactory.decodeResource(getResources(), R.drawable.s0);
c.drawBitmap(s000, X, Y, null);
s000.recycle();
s000 = null;

This will try to release the memory after drawing the frame.

EDIT

myImgLen = 30;
Bitmap bitmap = null;
for (int i = 0; i < myImgLen; i++) {
    bitmap = BitmapFactory.decodeResource(getResources(), getResource‌​s().getIdentifier("s" + i, "drawable", getPackageName()));
    c.drawBitmap(bitmap, X, Y, null);
    bitmap.recycle();
    bitmap = null;
}
