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.

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.
Actually I wanted to get GPS co-ordinates of a particular place when user long presses that place on map by using HERE Maps Android SDK. Is it possible?
Yes it is possible. Use Map#getSelectedObjects() to retrieve the list of POIs that the user has touched. If the object is an instance of MapCartoMarker, the gps coordinate of the object is stored in MapCartoMarker.
So I am trying to build an app that would allows the user to select a particular place from a Google Maps intent, and when the user pick a place, the intent would finish and return the latitude and longitude data to the previous activity.
What is the best way to do this?
What I have done so far:
I used GPSTracker from here.
to get the current latitude and longitude, and then used these data to start a google map intent pointing to current location.
The website you posted in your question does not look like it contains the actual map. If you need assistance with adding a Google Map to your application I would start here.
Assuming you have that working and your code allows a user to place his or her point already, you can retrieve the coordinates of that point by using a built in function in the Marker class getPosition().
You can use the coordinates by accessing the public variables .latitude and .longitude as follows:
LatLng coord = myMarker.getPosition();
double latitude = coord.latitude;
double longitude = coord.longitude;
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.?
I'm searching for a easy way to create Info-Windows for Google-Maps in Android.
For example: a function with longitude, latitude and text parrameters. These were show onclick a location on the map.
Thanks for help
