2Android BatchStepSensor Sample
3===================================
4
5Sample demonstrating how to set up SensorEventListeners for step
6detectors and step counters.

8Introduction
9------------
10
11This sample demonstrates the use of the two step [sensors][1] (step detector and counter) and
12sensor batching.
13
14It shows how to register a [SensorEventListener][2] with and without
15batching and shows how these events are received.
16
17The Step Detector sensor fires an
18event when a step is detected, while the step counter returns the total number of
19steps since a listener was first registered for this sensor.
20
21Both sensors only count steps while a listener is registered. This sample only covers the
22basic case, where a listener is only registered while the app is running. Likewise,
23batched sensors can be used in the background (when the CPU is suspended), which
24requires manually flushing the [sensor event][3] queue before it overflows, which is not
25covered in this sample.
