How to implement/debug a sensor driver in ANDROID

Does anyone know of a walk-through or any examples of any code to setup sensors in android.

I have the drivers available to me.

Also i have implemented the sensors library as instructed

in the Android开发者_开发百科-Reference along the sensors.h template.

I am still unable to get any response at the apps level.

How do i trace this issue? what might be the problem?

Thanks in advance

UPDATE:

Jorgesys's link below points to a great APP to test if the sensor drivers are functioning properly or not.

Now that i know they are not functioning, Any ideas of on where to dig??...

This is a cool example.

And the simulation of this project here.

Found everything needed to get started developing Android sensor apps.
