Detect Movements on Android Device

user12 · February 20th, 2012, 04:34 PM

Is it possible to detect whether the android device has moved in a certain direction and how much it has moved? For example, if I move my device 100 pixels to the left, a number would be displayed saying x is -100 pixels. If this is possible, which sensor would I use?

No, I'm asking if it is possible to detect much smaller movements, like 6 inches or something.

You could use the accelerometer i suppose as with any movement, there will be some sort of acceleration and deceleration.

Could you please provide an example? I don't know how to use the acceleration to determine the distance the device moved. Thanks.

I honestly don't have much experience with the Accelerometer APIs, so I would be learning just as you would be.
