How to detect movement of an android device?

Question

I need suggestion about how to detect the amount of movement of an android device. Suppose I have put the phone on a table or bed and then if somebody taps the table or sits

Answer 1

if you are trying to find the displacement of your phone, you need to find the Linear acceleration acting on your phone rather than the acceleration due to gravity

android has a built in converter to find the LINEAR ACCELERATION acting on your mobile phone

this is a code where you can see how to get the raw value of LINEAR ACCELERATION
