Using AnimationDrawable: Canvas: trying to use a recycled bitmap

I'm using Animation drawable to display a gif. I split the gif into frames, I created an animation file and I load it using:

animationImageView.setImageResource(splashAnimationResource);       
animation = (AnimationDrawable) animationImageView.getDrawable();

All this happens inside onResume(). After the animation has been displayed, inside onPause() I try to free memory:

for (int frameCounter = 0; frameCounter < animation.getNumberOfFrames(); ++frameCounter) {
        Drawable frame = animation.getFrame(frameCounter);
        if (frame instanceof BitmapDrawable) {
            BitmapDrawable castedFrame = (BitmapDrawable) frame;
            Bitmap bitmap = castedFrame.getBitmap();
            if (bitmap != null && !bitmap.isRecycled())
                bitmap.recycle();
        }
        frame.setCallback(null);
    }
splashAnimation.setCallback(null);

This all works very nice, animation is displayed correctly and memory is freed. If I try to go to the animation activity again, first time it works, but then it throws an exception:

I found the solution after banging my head for a couple of days. First you need to create smaller images size, for instance I was first using 400x400 size frames.. then i reduced to 100x100. Then i removed all the codes for bitmap recycling as there isn't any solution for this problem. Then u just play with animation.start() and .stop() and it would be really good.
