I ask this question in Stackoverflow but anybody answer to my question.
I am new in android programming and i want to write a program like cilenometer(link) but i don't know how can i write this program. I want to know, this values around ball obtained of accelerometer sensor, or orientation sensor or magnetic sensor or combination of these? What is '/12' after number?(for example the program writes: 0.5/12) The program shows three numbers, Do the numbers are for X and Y and Z axis? I searched in google and stackoverflow but i can't find any tutorial .
Thanks for your help and sorry for my poor english. Cheers
