why is this publicly exposed as a separate entry point from BuildOSCpuInfo()? 
If you're on android, obviously this will return you the android OS/Cpu info. 
If you aren't on android, then this function isn't of any immediate use
(obviously somebody will want to add spoofing support in the future, but that's
different).
