24  * This is an Android server implementation. It has as members a vrpn_Button_Server
25  * and some number of vrpn_Analog_Servers, as determined by the Java side. This
26  * implementation also has vrpn_Button_Remote and vrpn_Analog_Remote clients for
27  * the sole purpose of testing. All data from the Android is represented here
28  * as either Analogs or Buttons.
29  *
30  * All interaction between this class and the Java side are handled by the jni layer.
31  *
32  * It's worth noting that it is possible to pipe stdout to the Android log - directions
33  * for doing so are in the manual for this project - and all output is in the form of:
34  * fprintf(stderr, "..."), which we've found to be more reliable than other methods,
35  * including fprintf(stdout, "...").
