 * /9c3e74fI57bda9eb79ceaaa9c1b94ad49d9e462b52102149 (which only officially landed in Lollipop) changed from using
 * writeValue to writeString for Bundle keys. Some OEMs have pulled this change into their KitKat fork, so we can't
 * trust the SDK version check. Instead, we'll write a dummy Bundle to a Parcel and figure it out using that.
 *
 * The check is cached because the result doesn't change during runtime.
