How to mark evey next 100 meter travelled in map in android? - android

I am trying to get the GPS location co-ordinates(lat and lon vals) for every 100metrs.
For example, I am at particular location A and tried to fetch my current location using
location listener and shown in the map with marker, after that I have travelled 100metres and reached location B and again i tried to fetch location and shown in map with marker.
Good thing :-
i am getting but obvious new lat and lon cordinates for every next 100 meters.
Annoying Thing:-
Marker for location A and for location B getting overlapped always, so one cannot make out any sort of difference in between those two locations by dirrectly looking into map :(. How can I overcome this issue. Can you please guide me.?

get google maps data with retrofit 2

I try to get the distance between two points by showing them together with a polyline. One marker is permanently somewhere and the other the user chooses the place they want when clicking on the map. I tried with many codes obtained from the Internet but for me neither works or just gives me the marker of a place with the latutude and longitude. I want to use retrofit 2 to bring the information. Can anyone help me with that?
On clicking on map you are placing marker, So if you want to get location of that marker then simply you can got that marker position using that marker object like this.
Double latitude = marker.getPosition().latitude;
Double longitude = marker.getPosition.longitude;
and you have already one location so you can find distance between two locations using this.
locationFrom.distanceTo(locationDestination);
here locationFrom is your source location from where you want to find distance and locationDestination is your destination location to where you find distance.

Compare Marker.getPosition() and LatLang

My app gets updated GPS coordinates periodically which I show using a Marker on map. I need to move the marker to a new position if the new GPS coordinates are different then what Marker is currently showing.
The problem is that comparing Marker.getPosition() is more accurate while LatLang is not, hence sometimes even when they are the same, my logic says they are different.
How to solve this issue?
Please note that the same LatLang i assign to Marker.
You can consider that two LatLngs are virtually the same if the distance between them is less than a given tolerance.
You can use the SphericalUtil.computeDistanceBetween method from the Google Maps Android API Utility Library
float YOUR_TOLERANCE = 1; // 1 meter
if (SphericalUtil.computeDistanceBetween(pos, buslatLng) < YOUR_TOLERANCE) {
// Both locations are considered the same
}

Latitude and Longitude get changed every time I fetch them at same position

I am using android fused location api to get the latitude and longitude of same position but every time i get different latitude and longitude of same position last 4 digits vary every time at same position why so and how to get all the possible latitude & longitude of same position.
So please help me regarding this.
Location is generally accurate to only a city block, and will change within that. Try rounding off the coordinates to two decimal places and use those.

Dispalying route travelled using latitude and longitude values in map

I have an android app which will continuously send location information to server (latitude and longitude values). Another application will retrieve these info and display it in textview.
What I need to do is in my second app which displays in text view I need to add a mapview which displays the location tarvelled by marking it on map using the latitude and longitude values.
How to do it ? Thanks in advance !
As you have fetched the location information, now you just need to mark points on the map view to show the desired location on map view, You should follow using google maps android
Here you will find a good example on how to add markers on mapview.

How long will android take to give a latitude and longitude value of current location

Hi Friends im trying to take latitude and longitude value of current location.Iam moving to point A to point B.After reaching point B i start application more than 3times i got 3 diffrent lat and lang.After 3 rd time its giving the same lat and lang.
It depends on the location service that you use. For me, after setting the LocationListener usually first network location updates come in a second or two, GPS may sometimes take up to a minute.
