For ridesharing and deliveries solutions, routing includes the process of calculating a path along the road network, complete with an Estimated Time of Arrival (ETA). Clear searchI implement a project that draw path on google map when give source and destination points in android using Google direction Api. (In case of the Distance Matrix API, multiple combinations directly between origins and destinations are computed. Then, compare the estimated time of arrival (ETA) of different routes. Remember that Dijkstra’s algorithm executes until it visits all the nodes in a graph, so we’ll represent this as a condition for exiting the while-loop. I will try to explain my problem.

I usually respond fast (24-48 hours). This is probably the step that most tutorials will be skipping, because it's not about the code. And unfortunately, the algorithm you use will not give an accurate answer, because it gives the distance from the marker to the closest vertex on the path, not the closest point on the polyline itself, which will usually not be one of the points. The directions API will typically return the fastest route, but this isn't necessarily the shortest path. Use “@2x” to get “retina”/HiDPI image. Although the complexity, n log n , is fine the absolute time it takes is quite large.
