-This folder contains example code for writing native apps that use Brillo
-sensors. The sensors HAL implementation must exist on the device for the apps
-in this folder to run successfully.
-
-Example files:
-  hal-example-app.cpp:
-    An example app that uses the sensors HAL (defined in
-    hardware/libhardware/include/sensors.h) directly. In the app, the list of
-    sensors found on the device is printed. And if an accelerometer exists, the
-    app will read the data and print it out.
-
-  ndk-example-app.cpp:
-    An example app that uses the NDK sensors interface. In the app, the list of
-    sensors found on the device is printed. And then the app tries to read data
-    from accelerometer, proximity sensor, and significant motion sensor, which
-    has continuous, on-change, and one-shot reporting modes respectively.
-
-  sensors_hal.cpp
-    An example implementation of a sensors HAL. It implements a fake
-    accelerometer and custom sensor (defined in example_sensors.{h|cpp}). The
-    accelerometer always returns random data. The custom sensor returns the hour
-    for the local time.
-
-    To use this HAL implementation, push the binary file sensors.example into
-    /system/lib/hw/ folder and rename it to sensors.default (make sure there is
-    no other sensors.* file under that folder).
