/**
|
||||
* Example Test Case to test using Android sensors as Joystick axes. Make sure to enable Joystick Events from
|
||||
* the test chooser menus. Rotating the device will cause the block to rotate. Tapping the screen will cause the
|
||||
* sensors to be calibrated (reset to zero) at the current orientation. Continuously tapping the screen causes
|
||||
* the "rumble" to intensify until it reaches the maximum amount and then it shuts off.
