+A basic sample showing how to use the Gravity sensor on the wearable device
+by counting how many jumping jacks you have performed.

+ <intro>
+<![CDATA[
+[SensorEventListener][1] offers you methods used for receiving notifications from the
+[SensorManager][2] when sensor values have changed.
+
+This example counts how many times Jumping Jakcs are performed by detecting the value
+of the Gravity sensor by the following code:
+
+```java
+@Override
+public void onSensorChanged(SensorEvent event) {
+ detectJump(event.values[0], event.timestamp);
+}
+
+private void detectJump(float xValue, long timestamp) {
+ if ((Math.abs(xValue) > GRAVITY_THRESHOLD)) {
+ if(timestamp - mLastTime < TIME_THRESHOLD_NS && mUp != (xValue > 0)) {
+ onJumpDetected(!mUp);
+ }
+ mUp = xValue > 0;
+ mLastTime = timestamp;
+ }
+}
+```
+
+The detectJump method above assumes that when a person is wearing the watch, the x-component of gravity
+as measured by the Gravity Sensor is +9.8 when the hand is downward and -9.8 when the hand
+is upward (signs are reversed if the watch is worn on the right hand). Since the upward or
+downward may not be completely accurate, we leave some room and instead of 9.8, we use
+GRAVITY_THRESHOLD (7.0f). We also consider the up <-> down movement successful if it takes less than
+TIME_THRESHOLD_NS (2000000000 nanoseconds).
