I have researched a lot on google maps android to dynamically plot the route as the person travels. I found that polyline gives a closed polygon with multiple points on it, which does not look good. So what is the best method to plot the exact route as traveled by a person as per the latitude and longitude.
You will have to use the Google Maps Directions API to build your route map.
https://developers.google.com/maps/documentation/directions/intro. Also refer to the detailed SO answer which may help you understand its implementation.
Answer : Draw path between two points using Google Maps Android API v2.

I am trying to find the location distance between two places as well
as the time and direction/path alongside the road, not the
displacement. but I am unable to do it with free map API. I heard
that to find direction, you need to pay for google maps API. Is it
true? If not then how can I do this?
The second ambiguity is when I try to find the location distance
between to locations, I am using location1.toDistance(location2)
which I think gives displacement not the distance along the road.
because when I search the same location distance on google map i-e
Google Maps Google maps url
Then the distance is greater when I tried to find the same location
distance with the location1.toDistance(location2). so how to solve
these problem?
Has been searching and wondering if I can develop this function with Google Maps API.
Basically I wanna do is
Have a fixed route on Google Map
Calculate the length of that route
Based on a number of some lengths, and show where it's located on the route.
I'm reading the documents, but can't find the API for them.
Thank you for your attention and help.
Im working on a Android project which should trigger a method when i come near a road from a building or something
is there a way to detect near by road in android ?
Use the Google Maps Roads API, more specifically use the snap to roads feature which snaps the points (lat/lng) to their most likely position on roads using the Roads API.
I have a problem: I need to calculate the routing within a mall that has a plan registered in google maps, but with the direction API can not get the indoor routing. To be precise if I am away from the mall and I want to calculate the route to an internal area, I am guided to the outside of the mall, while I would like my app would calculate a route for the section inside the building . To do this I currently use the Google Maps Android API v2 and the Direction api with json output. Does anyone have any suggestions for me? sorry for my bad English
I have exactly the same problem; compting a route (with mode=walking) between two points that are both inside a mall gives a path that starts, goes and ends out of the building.
The closest similar path found on Google Maps (HTML version, from a browser) is the "bike" one...
how can I implement algorithms such as Dijkstra or backtracking on Google Maps integrated in Android ? For example I want to compute a route from city A to city B such that I pay the lowest price for gas.
Check this post. It has the Route finding Example. Google removes the Route finding api. But we have develop the code for the draw the route using Overlay. this is what done on that working example.
Since Google Maps doesn't provide access to the actual road data, I don't think it is possible to implement your own routing algorithm.
You could use road data from another source such as http://openstreetmap.org .
