Android BatchStepSensor Sample
|
|
===================================
|
|
|
|
Sample demonstrating how to set up SensorEventListeners for step
|
|
detectors and step counters.
|
|
|
|
Introduction
|
|
------------
|
|
|
|
This sample demonstrates the use of the two step [sensors][1] (step detector and counter) and
|
|
sensor batching.
|
|
|
|
It shows how to register a [SensorEventListener][2] with and without
|
|
batching and shows how these events are received.
|
|
|
|
The Step Detector sensor fires an
|
|
event when a step is detected, while the step counter returns the total number of
|
|
steps since a listener was first registered for this sensor.
|
|
|
|
Both sensors only count steps while a listener is registered. This sample only covers the
|
|
basic case, where a listener is only registered while the app is running. Likewise,
|
|
batched sensors can be used in the background (when the CPU is suspended), which
|
|
requires manually flushing the [sensor event][3] queue before it overflows, which is not
|
|
covered in this sample.
