What is the best way to calculate the distance between two points/Or we can say while we walk calculate distance traveled using accelerometer? My main question is that i'm working on an application in which i need to count distance using two locations but sometimes the core locations fails to update location so at that time how do i calculate the distance traveled?

You can't even get an accurate measurement of velocity from the accelerometer, so you're definitely not going to be able to get an accurate measure of distance traveled.
