<p>
|

|

This sample demonstrates the use of the two step sensors (step detector and counter) and
|
||||
sensor batching.\n\n It shows how to register a SensorEventListener with and without
|
||||
batching and shows how these events are received.\n\nThe 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 queue before it overflows, which is not
|
||||
covered in this sample.
