When is a Nexus 5 phone more than a multi-use communication device? When it's controlling an X-Ray gun! SDG Systems was approached by Tribogenics Inc to retrofit Google's Nexus 5 phone to act as a controller for their prototype X-Ray Florescence Processing (XRFP) gun. SDG was to pare AOSP 4.4 down to a single application and then to act as the brains of the gun, communicating with the various elements and controller boards to create a cohesive and user-friendly unit.

Throughout the project SDG came up against a series of interesting problems which Ben will lay out along with the solutions that they came up with. Some of these issues include: Pre-5.1 'kiosk' mode, simultaneous USB Host mode and charging, external video, reusing Android settings, retrofitting the status bar and statically linking against NDK libraries within Android Studio.
