<p>The {@link android.hardware.SensorManager} APIs now allow you to request a callback when the
device sensors detect "significant motion." For instance, this event may be triggered by new
motion such as when the user starts to walk.</p>
<p>To register a listener for significant motion, extend the {@link android.hardware.TriggerEventListener} class and implement the {@link android.hardware.TriggerEventListener#onTrigger onTrigger()} callback method. Then register your event listener with the {@link android.hardware.SensorManager} by passing it to {@link android.hardware.SensorManager#requestTriggerSensor requestTriggerSensor()}, passing it your {@link android.hardware.TriggerEventListener} and {@link android.hardware.Sensor#TYPE_SIGNIFICANT_MOTION}.</p>

<p>The new {@link android.hardware.Sensor#TYPE_GAME_ROTATION_VECTOR} sensor allows you to detect the device's rotations without worrying about magnetic interferences. Unlike the {@link android.hardware.Sensor#TYPE_ROTATION_VECTOR} sensor, the {@link android.hardware.Sensor#TYPE_GAME_ROTATION_VECTOR} is not based on magnetic north.</p>
