This is the way how the stock camera app disables rotation animation:

private void setRotationAnimation() {
    int rotationAnimation = WindowManager.LayoutParams.ROTATION_ANIMATION_CROSSFADE;
    Window win = getWindow();
    WindowManager.LayoutParams winParams = win.getAttributes();
    winParams.rotationAnimation = rotationAnimation;
    win.setAttributes(winParams);
}

Note: According to API Reference and comment below, this only works:

• On API level 18 or above
• The FLAG_FULLSCREEN flag is set for WindowManager.LayoutParams of the Activity
• The Activity is not covered by another window (e.g. the Power Off popup triggered by long pressing the Power button)
