Can you document somewhere that calling this is necessary for device/bluetooth
to work on Android?

https://www.chromium.org/developers/design-documents/android-jni and the details
of the sample JNI code sort of cover this. It's not super friendly doc, I had to
ask some questions of android devs, I plan on improving it some, but details are
there when you dig.
