The attached project wraps this Github project. The library files are in the /files folder of the attached B4A project. Copy them to your additional library folder. Also posting the Java code. You will also need to enable the Phone library in the B4A project. Move your device in different directions and see the compasses changing accordingly.

I would be very happy to use some of your libraries in my app. Where can I donate ?
Hey guys i think it's right to make a small donation to colleagues as @Johan Schoeman ,@DonManfred, etc. It is very fair because they give us many beautiful libraries.
I wait your notice Johan.
Thank you again for your great work
I am doing this purely for the fun of it @MarcoRome. You can use whatever you want (of what I have posted) in your apps. No need to donate anything. My "payment" is the satisfaction of seeing it "work"....;)

Just a note:

You do not need a device that supports phone sensors (PhoneOrientation - as my tablets do not).

I use it with GPS.
compass1.CompassDegrees = Location1.Bearing

This works perfectly well - setting the compass to show your current heading.

Thanks for this wrap.
