Android ImageSwitcher - OutOfMemory when switching images (very small)

Question

I got some OutOfMemory crashes when switching image in ImageSwitcher, it's very rare but it happens sometimes (never to me, otherway I would be able to debug it haha).

I only have 5 images (PNG) and each of them has something between 10-60kb, so to be honest I am quite surprised. Here is code:

frameImages = new int[]{R.drawable.f_0, R.drawable.f_1, R.drawable.f_2, R.drawable.f_3, R.drawable.f_4};

...
public void switchImage() {
    int frame = getFrame();
    int image = frameImages[frame];

    // imageSwitcher.startAnimation(getAnimation());
    if (frame == 0)
        startYAxisRotation(imageSwitcher, 400);

    imageSwitcher.setImageResource(image); //CRASHES HERE
}

Am I doing something wrong?

Answer 1

So, solution was to decrease resolution of images (I did manual resizing in photoshop). From 620x1080 to 800x460 and everything works fine.

Conclusion: Image size it's not that important - image resolution is.

PS: MatPag should also be teoretically correct, it's practically same what I did - except he is doing that in code, I did it manually in photoshop by myself. But I think doing that manually is better IMHO.
