How can i build /hardware/libhardware/tests/nusensor?

Question

I'm just beginner of Android and i'm using kitkat(4.4.4) source.

When i try to bulid android (not kernel), always don't build

 /hardware/libhardware/tests/nusensor.

That's why i can't find its result excutable file named test-nusensor though i need it.

How can I build that file in that directory? and How can I execute result of build?

If you have already built the entire android source you can build the nusensor-test module seperately. Follow these steps to build that module alone -

• Run source build/envsetup.sh from the android root folder
• Run lunch and select the correct device you want to build for.
• Go to /hardware/libhardware/tests/nusensor folder and run mm
• The executable should get generated and it will be present in out/target/product/msm8974/system/bin/ with the name test-nusensors
• Push the executable to the device - adb push out/target/product/msm8974/system/bin/test-nusensors /system/bin
• To run it use the command adb shell /system/bin/test-nusensors
