Hi.

I need to obtain the velocity of an android device, based on the accelerometer values. I made a code that allows me to get the accelerometer values, and then I calculate the velocity, using the formula: v = v0 + at. (vector calculation)

My problem is that my velocity only increases and never decreases. I think the problem is that the device never gets an negative acceleration.

Can you help me with this?
