Get latitude and longitude before the last element

I'm trying to get the distance between a whole track , so what I'm trying to do is the following.



First setup a listener that will trigger every lat lang changes, then just get the latest lat lang and get the lat langs before the last one , so I can measure the distance between the last lat lang and the previous one, then I'm planning to put it all into an array to sum it up and have the total distance when I stop my track.



I'm using a linkedlist to save latlangs



 mLinkedList.add(new LatLng(location.getLatitude(), location.getLongitude()));



 float results = new float[10];

                   Location.distanceBetween(needThisLatitude,needThisLongitude,locationResult.getLastLocation().getLatitude(),locationResult.getLastLocation().getLongitude(),results);

//Then I will save that results into an array and sum them up to get total distance.

Quarantine

For other uses, see Quarantine (disambiguation). Signal flag "Lima" called the "Yellow Jack" which when flown in harbor means ship is under quarantine. A simple yellow flag (also called the "Yellow Jack") had historically been used to signal quarantine (it stands for Q among signal flags), but now indicates the opposite, as a signal of a ship free of disease that requests boarding and inspection. A quarantine is used to separate and restrict the movement of people; it is 'a restraint upon the activities or communication of persons or the transport of goods designed to prevent the spread of disease or pests', for a certain period of time. [1] This is often used in connection to disease and illness, such as those who may possibly have been exposed to a communicable disease.
