Bitmap load outofmemory android

Question

I am making a wallpaper with different bitmaps that are moving and rotating using matrices. Right now, I have 8 bitmaps with size about 300 X 300 each as pngs. I need them to be on screen at all times. I am using this in the onCreate:

sun = BitmapFactory.decodeResource(getResources(), R.drawable.sun);
            planet_1 = BitmapFactory.decodeResource(getResources(),
                    R.drawable.planet_1);
            scene_1 = BitmapFactory.decodeResource(getResources(),
                    R.drawable.full_scaled);
            planet_2 = BitmapFactory.decodeResource(getResources(),
                    R.drawable.planet_2);
            scene_2 = BitmapFactory.decodeResource(getResources(),
                    R.drawable.scene_2);
            planet_3 = BitmapFactory.decodeResource(getResources(),
                    R.drawable.planet_3);
            scene_3 = BitmapFactory.decodeResource(getResources(),
                    R.drawable.scene_3);
            bg = BitmapFactory.decodeResource(getResources(), R.drawable.bg);

They load up in the preview well but when I try to set wallpaper it crashes with:

You can try with something like this

BitmapFactory.Options opts = new BitmapFactory.Options();
opts.inPreferredConfig = Bitmap.Config.RGB_565; // or Bitmap.Config.ARGB_4444
sun = BitmapFactory.decodeResource(getResources(), R.drawable.sun, opts);

This is the easiest approach and worth trying. Of course this will make Your graphic worse quality but depending on what they look like You may even not see the difference.
