-    It shows how to register a [SensorEventListener][2] with and without
-    batching and shows how these events are received.

-    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.
