I want to receive roads information from Google Maps API like the regular street info.
For example, in the Google Maps application, you can see the traffic in each road. Is there any way to receive this info in data and not just view on the screen?
I need to get information such name, traffic, speed-limit and point of start and end.
I think about something similar to the existing streets info, I will give a location (long,lat) and the system will return the nearest roads around (maybe crossroads also).
Is there any way to get this information with Google Maps API? If not, there is another service that can provide this info?
I tried to find some details but I can't find anything...
You can use Google Directions API for this. It provides you closest directions, distance and time to travel. I also recommend using Google-Directions-Android library for parsing all that stuff, it really saves a lot of time.

I'm building a route recommendation app in Android Studio where the user can see the best route between two destinations on the map. I am using Google Maps APIs for that and I know that it's using Dijkstra's algorithm to determine the route. But I wonder if the API can update the route according to real-time traffic, I didn't find any information about that.
Google Maps is updated constantly – literally, every second of every day!

I've been researching for a long time in finding tutorials.
This is what i want to attain/make, Credit to Voyage: Route Planner
That application itself is similar for what i want to make.
Questions are:
-How to plot multiple destination and provide Route for the user in Google map?
-Is there any books/tutorials/website that i can read/use/watch to learn more about google map?
How can i give the directions to the user after i provide the route? or how can i do this?
-I've already saw similar question like this but then it is written in Javascript.
Thank you.
To answer your questions:
How to plot multiple destination and provide Route for the user in Google map?
As far as I know, multiple destinations support hasn't been an added feature yet for Android as also discussed in this thread.
However, you can get some ideas about getting directions for multiple destinations from the given suggestion in Google Maps Help Forum and routing from this YouTube video - Google Maps Routing Multiple Destinations
Is there any books/tutorials/website that i can read/use/watch to learn more about google map?
You may use these helpful references, video and others
To plan a route through a series of up to 23 locations using the Google Maps Directions API, you can use Waypoints.

How can i give the directions to the user after i provide the route?
As discussed in Directions Requests, this can be done by sending HTTPS or HTTP requests and adding certain parameters with the following format:

I hope that helps.
New to Stackoverflow, did some searching and couldn't find anything that really matched what I'm looking for unless I'm using the wrong keywords. I did find guides on how to plot a route when you know the actual route, but I'm looking to do it from actually walking it, see below:
I'm fairly new to web development and am looking to plot maps of a trail on a website using an embedded Google map or some other free map platform if it's suitable (OSM?) I have an Android phone and I'd like to actually be able to:
(1) walk this route,
(2) take the GPS data somehow &
(3) match it up to a Google map to
(4) post it on my webpage.
That will help visitors know the actual route (which is not available on Google Maps in any detail) and have somewhat of a "guide" of the near-exact trail route. I imagine this can be done, as Runkeeper and other applications do this (with additional data on speed, time, etc.) for tracking your runs. I don't really want any of that additional data as much as I would like to just capture the GPS route itself, and have it in some format that I can then use to make a map out of automatically. Not sure where to start with this, or if it can be done easily. Any information or guidance would be greatly appreciated. I have no experience in Java; very limited Javascript and OK in HTML/CSS. I've never used the Google Maps API either.
Thanks!
You may use API Picker lists to help you on the most common things you may want to do on a map or with location-based data, and this also suggests the API that most suits your needs.
Listed below are the useful APIs to plot a route on a map:
Polylines in the Google Maps Android API
Polylines in the Google Maps SDK for iOS
Polylines in the Google Maps JavaScript API
Directions mode in the Google Maps Embed API
Paths in the Google Static Maps API (a web service)
Links of useful APIs for whatever you want to do on a map can be found in the documentation.
We would have all used the google maps app on android, so my question is little relevant to that.
In the gmaps for android app, when I choose a driving route, the route gets displayed on the map with voice and text commands. Suppose I deviate from that path, it recalculates the route and alerts me saying follow the original route.
So my question is, can we do this in the google maps API that is provided for android in our own app? If so what is the best followed approach.
My use case goes like this: I have a user who will start his journey to a set of client hotels, and if the transit he takes deviates I simply have to alert him saying he is following a wrong route or he has to follow the modified route. Kind of a security feature.
Are there any best practices for an app to get the same geo location as the Google Maps app?
For example, my app lists nearby Sprockets based on a user's geolocation. Often the geolocation I come up with is different than what the Google Maps app comes up with (which is often more accurate).
We can kind of do this if we have a MapActivity and use MyOverlay - this should give us the same location google maps would show - but we always need to display a map to use this. I'm almost considering just hosting a hidden map on my activity in order to use MyOverlay and grab better location updates! Any more sane way of doing this?
Thanks
Android has a full location API. This is what the map system uses.
A good direction to look is the open-source Foursquare app's location code if you're looking to manage location reports from multiple providers (GPS, network, etc.) and balance freshness and so forth. IMO their solution is a bit overarchitected for most needs, but the basic ideas are pretty easy to grok from it.
