Use of ALooper_pollOnce has been Deprecated in later Android releases

[Neil-Clifford-FB]

as per: https://developer.android.com/ndk/reference/group/looper#:~:text=Calls%20to%20ALooper_pollAll%20should%20be,if%20they%20also%20indicate%20ALOOPER_POLL_WAKE.

The example code as part of the tutorial still makes use of ALooper_pollAll and needs to be replace with ALooper_pollOnce

e.g.
