i working with google map directions api in android application.when i send two Location to google api it return route between both but LatLng is changing and no one send me.Is there a way to do this?
You have to implement LocationListener to locate user's device GeoCode.
That will take some effort. You could refer the demo I made here mClima
The listener for location change was implemented in MainActivity. Remember to declare permision in AndroidManifest

i'm setting a new project in flutter with flutter_google_maps for tracking user location on map it's a basic project
But when i am moving devices or ride then my Location are point on map but not right place
Ex.
I am walk on street road then google map navigation show exact my
location But my project not show exact location
Code are normal just use Flutter Location Plugin
And Track Location Using this code
location.onLocationChanged().listen((LocationData currentLocation) {
print(currentLocation.latitude);
print(currentLocation.longitude);
});
And set to marker target value describe in google_maps_flutter
i google lot of things but no answer found who resolve my problem
Where I'm wrong ya any other methods use by other location tracking app
Thanks
I'm building a mobile-version of a website, trying to have one-click link to launch Google Maps with driving directions to the business, from the user's current location. I have it working fine for the iPhone, but when testing on Android, it views 'Current%20Location' and tries to find a business called 'Current Location'. Here is my current code:
Get Directions
I need a universal string to search from the current location, and can't find a definitive answer anywhere online.
Thanks in advance for any help!
I am doing the same thing and now have it working on Android. I don't have an iPhone so I have no way of testing on that. You should leave the saddr parameter blank in the URL, and Google Maps will then prefill it with the user's current location. Also, use + signs instead of spaces in the destination address. Here's the corrected URL:
http://maps.google.com/maps?saddr=&daddr=123+Street+Rd,Cityville,MD,21098
Use the google gps api to get the currentlocation and pass it to maps. Even better I think there's an action to open the built-in maps application asking it to route from current location to your address.
This article on location services should help http://developer.android.com/guide/topics/location/index.html
If you're trying to do it fully through the web, I think the user has to enable location services on the google webpage for it to work.
Also, check out this javascript library that provides a platform neutral api for gps services on most devices http://code.google.com/p/geo-location-javascript/
Google Maps with directions from current location
https://maps.google.com/maps?saddr=&daddr=35.658157,139.697174&sensor=TRUE
https://maps.google.com/maps?saddr=&daddr= PLUS
"location's_latitude" PLUS
"," PLUS
"location's_longitude" PLUS
"&sensor=TRUE" // for getting your current location
Probably the most accurate way using lat and long
<span class="addressAt">
<a href="http://maps.google.com/maps?f=d&hl=en®ion=US&doflg=ptm&geocode=&saddr=&daddr=41.75553,-88.322048" target="_blank">213 S River St
Aurora, IL</a>
</span>
This is the only way to get an accurate "my location" on the google maps mobile site. Replace the coordinates(41.75553,-88.322048) with your locations coords. All other ways just wrote in my location as the start address without actually getting the real time location.
From my app I would like to start the Google Maps App with a provided location and a marker. The marker should indicate, that there is something on that given location.
For now, I have the following code, which starts with an Intent the Google Maps App with the provided location (51.49234, 7.43045).
startActivity(
new Intent(
android.content.Intent.ACTION_VIEW,
Uri.parse("geo:51.49234,7.43045")));
When the Google Maps App starts, it looks like the following:
No marker is shown. I would like, that the Google Maps App would show a marker on that position, which is given through the Intent. Is there any "hidden" Intent URI's which I can use to show a marker within the Google Maps App?
Thanks in advance.
Solution
#Rajiv M. pointed me to the idea of querying the surroundings with the given location.
So, the solution is: Query the surroundings of your given location with your given location as the parameter. The URI looks like:
geo:51.49234,7.43045?q=51.49234,7.43045
Google Maps will show the query-result as the street name:
Kind of a hack, but it seems to work well.
Why you should not use 0,0 as the map location
geo:0,0?q=51.49234,7.43045
When you start Google Maps App with the provided map location point 0,0 , Google Maps App will start searching for your current device position. And this takes time. In some cases, when GPS signal is not provided, way too much. Until then the Google Maps App will start searching for your query 51.49234,7.43045.
Try starting Google Maps using the same intent, but with a URI of the format:
geo:34.067214,-118.349332?q=410+Hauser+Boulevard,+Los+Angeles,+CA
i.e. geo:0,0?q=street+address
The application should then actually show a point at that address. If you do not have the address, you may have to use a service to translate it to an address for this to work.

The other option is to embed a MapView in your application and add a marker within that. A tutorial for using MapViews / Markers with-in your application can be found at http://mobiforge.com/developing/story/using-google-maps-android.
Maybe you can try to put ur uri as below:
Uri uri =Uri.parse("http://maps.google.com/maps?q=" +_lat +","+_lon);
At least the above code work for me. It help me add a pin point on top of the location i search for. furthermore, the pin point will have a small dialog box to press on, it provide me the function of searching the direction to that location. :D
i don't wanna use a MapView an some Overlays. I only want to use the given intent Google Maps. Showing a Adress in Google Maps works fine when i call it from my application using Uri.parse("geo: ...") ... But i only see the map centered at the given adress. There are no marker or "bubble" like they are when i do a search in google maps. I can define the Zoom in the Uri with "z=12" ... Is there one thing i had to set up to see the marker and the "bubble"?!
Thank you!!!
Is there one thing i had to set up to see the marker and the "bubble"?!
There is no documented and supported means to put a "marker" or "bubble" when you use a geo: URL. Bear in mind that it might not be Google Maps that winds up responding to that URL -- the user could have installed another mapping application that they choose to handle such requests.
i have successfully displayed google map in my app . but i am not able to search the specfied location . can u please put the code snippet or any link available for the code .
To get a location (latitude and longitude) from a location name(e.g. "paris" or "japan"), use Geocoder.getFromLocationName()
To display a specific latitude/longitude on the map use MapControl.setCenter()
