As Qt is not able to pull the pairing data from a device, a lengthy
discovery process is needed to see what devices are paired. On
https://forum.qt.io/topic/46075/solved-bluetooth-list-paired-devices
user s.frings74 does, however, present a solution to this using JNI.
Currently, this code is taken "as is".
Currently, only for Android (so not mobile-on-desktop, or even desktop).
And only generating logging data in the logcat.
