This is a cleaned up version of code posted here: http://www.eevblog.com/forum/thermal-imaging/question-about-flir-one-for-android/
All credit goes to tomas123, cynfab etc from that forum who did the awesome research and work to make this support.
The branch g3 of this fork adds support for FLIR ONE G3 cameras (it may also work with PRO LT models), that have a sensor with 80x60 resolution.
It also adds some command line options, that can be displayed by running the program without any arguments.
The --pro flag should make it compatible with FLIR ONE G2 and PRO models, although I don't have one of those to test.
