Problem one: it requires its own binary, which we haven't built. There are instructions in sdl/src/hidapi/README.txt, if we ever want to try. Problem two: the Android app segfaults when `hid_init()` calls `g_JVM->AttachCurrentThread()`. This might be a bug in NDK 21's jni.h, but that seems unlikely. Perhaps a version mismatch? In any case, we aren't using the code at the moment, so the easy answer is to leave it out.
