I have a web application, in which we add lat and lng and in web it shows driving route clearly in the map. I have send the same details including api, lat and longitude to the android using json. But in android app, map doesn't show proper path.

any help?
Update:
I tried with solution one and solution two
In both cases, i am getting error : OVER_QUERY_LIMIT
Anyone has any solution for this???
This is how i am getting in android map..i want them to show in actual road path.
In website, it shows correctly...

On Google Maps, enter and select your destination. Tap Directions. The map will show the route Google Maps has chosen in blue.
To display actual road path in Android map you can use geodesic(true) like given below.
Polyline line = map.addPolyline(new PolylineOptions()
.add(new LatLng(-37.81319, 144.96298), new LatLng(-31.95285, 115.85734))
.width(25)
.color(Color.BLUE)
.geodesic(true));
As per this link (Read Geodesic segments)
The geodesic setting determines how the line segments between consecutive vertices of the polyline/polygon are drawn. Geodesic segments are those that follow the shortest path along the Earth's surface (a sphere) and often appear as curved lines on a map with a Mercator projection. Non-geodesic segments are drawn as straight lines on the map.
Set this property on the shape's option object by calling *Options.geodesic() where true indicates the segments should be drawn as geodesics and false indicates the segments should be drawn as straight lines. If unspecified, the default is non-geodesic segments (false).
For OVER_QUERY_LIMIT :- Use of the Google Maps APIs web services is subject to specific limits on the amount of requests per 24 hour period. Requests sent in excess of these limits will receive an error message.
If you exceed the usage limits you will get an OVER_QUERY_LIMIT status code as a response.
This means that the web service will stop providing normal responses and switch to returning only status code OVER_QUERY_LIMIT until more usage is allowed again. This can happen:
Solutions :-
The above problems can be address by combining two approaches:
Check this link for detail information.
Hope this will help you.

Over query limit means that you are performing too many queries per second to the API or that you have exceeded your quota.
In order to further assist you I would need in detail which APIs you are using, since I don't know that I am assuming you are using the Google Maps Roads API which does give you the paths you want.
Every API has a usage limit. In the case of the Roads API you can only make 50 Queries Per Second (QPS) and you have other limitations. To see the list of limitations regarding this API I encourage you to check the link bellow:
If you are not using the Roads API, you will have to find which API you are using, and the limitation for it. Following is a list of all the APIs Google Maps offers:
Once you have the previous steps figured out, you have usually two main options to avoid hitting the limit:
Each solution is a world on its own, but I will leave you with some directions on the concepts so you have an easier time following them:
I specially recommend the last link, which points to official documentation and covers both caching and throttling.
Hope it helps !
PS: I also upvoted the question, seeing no real reason why someone would downvote it. I do recommend however that you add a Minimal Working Example instead of posting all your code, and it will make more people willing to help you.
In an Android case, I usually recommend creating a project from scratch as minimalist as possible that can replicate your issue.
