What does this string in the Manifest mean?

What exactly does "0x000004B4" mean? I have seen android:configChanges= before when regarding screen orientation, or pixel density, but have no idea what these letters and numbers mean. I'm very new and would like to know how the more commonly seen strings work. Much appreciated.

I can tell you that each attribute in the "android:configChanges" field resolves to a different value:

So my guess is that the attribute values somehow add up to uniquely identify which attributes were added in the Manifest.
