When you draw a polyline, those points near the turns are not accurate while moving they are placed on the top of the buildings and sometimes instead of a proper polyline there is a line from the source to destination.What I want to do is a polyline must stick on to the road.So how do I fix this?
I am following this link:
Please find the screenshots for more clarification.

i am getting a fully loaded map in my android app, and i am getting some directions waypoint using the directions API. What i would like to accomplish now is check if the desired route form A to B intersects with another polyline.
Can someone shed some light into this?
Thank you very much, cheers!
Loop for each straight line in first polyline
Loop for each straight line in second polyline
Test if both straight lines intersect. They both intersects if there exists one point that both line share.
Line equation if endpoints are known:
I draw a polygon between two latitude and longitude but polygon line shows far from road.
Like the picture above, blue polygon line shows far from road. Where polygon line is draw there is no road. Anyone can help me to draw right polygon between two latitude and longitude.
Thank you!
If you want draw a route between two address, you should use Directions API.

I have a problem with polyline in android
as you can see in the picture above, it has a line that drawn long to the bottom of my map, but that line is not supposed to be there
but when I follow that line to the bottom or I zoom out the map like the picture above, the line is gone
is there anyone can help me?
For each vertex (location) in polyline. You can specified the level which will indicate the location that will appear on that level. For example decrease in zoom. If a location does not appear on a given level, then the line will go from the last visible location to the next visible location. Note that the first and last locations must be Level 3 points, otherwise the polyline won't display on all levels.
Check this page for more information.
You can use polyline's properties such as points which is the vertices of the line. This line segments are drawn between consecutive points. A polyline is not closed by default; to form a closed polyline, the start and end points must be the same.
Check this page for the other properties.
Can anyone, help me draw a circle or rather precisely an Arc with a given center point (GeoPoint) and the start and end points as well. So basically, it should help me draw a sector with given center point along with start and end points. I'm planning to use PathOverlay as my baseclass from OSMdroid, so that it would be easier for me to remove or add.
I understand the greatCircle provided in PathOverlay of OSMdroid, but not quit sure how to make use of it, I was wondering if any sample example be provided. Also How would I set the center of this GreatCircle.
Don't use a PathOverlay to draw filled polygons: as you noticed, this doesn't work properly when portions of the polygon are outside the screen.
for filled polygons, use an OSMBonusPack Polygon.
For setting the points of your arc, there is no ready-to-use API currently.
A "great circle" on a map represents the shortest "as the crow flies" path between two points. It is going to look like a straight line on your map. You need to think of the Earth as a sphere when considering the centre of the great circle; the centre is of course, the centre of the Earth.
I am using Google Map Api V2 and I can marker or draw a line between two points.But I try to draw a line through the route of a bus.So Route,Ways,Stopping places...etc of the bus are already known.First of all, I tried to find all LatLong values of the route and I draw it as polylines but I guess it is wasting time.So I want to draw line without find out all LatLong points of route of the bus.Is there any way ?
Thanks for the help..
You can use the Directions API to get the directions between two points, but this probably wont match your bus routes.
