Android :: how to calculate distance while walking in android?
There are different ways to do this:
1.GPS: Keep adding GPS distance between 2 points every X seconds (say 10 sec). Check Android Location.distanceTo or distanceBetween. Check
My Tracks app, it is open source. GPS is not available indoors and
would have error if user is changing direction very frequently (read
every 1-2 second)
2.Accelerometer: Look for code/library for step detection using accelerometer. Distance comes from double integration of acceleration,
errors can add up very quickly here.
3.Step detector: Built-in in Nexus 5. Google must have taken care of accelerometer errors to extent possible. This is hardware-based
computation, consumes less battery but not available in most of
handsets as of date.
The 2nd option seem very similar to what you suggested and I do think its the best way to achieve it since iOS and Android defer in code and in functionality therefor the best method to achieve it is saving currentLocation and previousLocation in a while loop that will .sleep() and just sum the entire loop as the distance traveled.
the bigger question is this supposedly app is a distance summerizing app? does it just a small function inside of it? how do you decide when to stop calculating the distance?
