Accelerometer Data App -- 2

Please check out the PDF attached for details on this project. This will be stage 1 of about 3 stages so whomever freelancer that gets the project will have the choice to code for stages 2 and 3 when they come around (unknown time frame at this time). Basically I will need a VERY VERY accurate accelerometer data readings for X, Y and Z. I do consider this first stage to be the basic "ground work" so to an experienced Android app programmer this should be a walk in the park to do. And still keep in mind that you will be paid 2 more times if I choose you and you want to continue with the other 2 stages once they are in place (again, no time frame on this yet).
