Mobile web driving directions from current location - android

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&region=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.

GeoCoords from Android Google Maps SEND Intent

Hello my fellow coders,
I am trying to retrieve GeoCoordinates from an Android Google Maps SEND Intent (as dispatched when selecting to share a selected location) and even after searching around and trying various approaches for hours now I can't seem to get anywhere. However, all I seem to get from the Intent seems to be a text/plain content like this:
Franziskaner Wirtshaus & Biergarten - Trudering-Riem, München
https://some/shortened/maps/link
I tried (amongst others) several approaches from:
Get GeoCodes from Android Google Maps App (Not applicable since it opens a new activity)
How can I find the latitude and longitude from address? (Geocoder and Geocoding REST API from Google - no suitable results)
None of the above solutions yields any usable results.
Is there a reliable way to get GPS coordinates from something a user selected in Google Maps on Android at all?
Thanks in advance for your help,
Alex
I don't know if this app helps you. you can copy coordinates to clipboard or open it with other third party maps
cheers

How can I control my direction type preference in the new Google Maps link URLs?

I would like to be able to have a Google Maps direction link which, when opened on mobile (Android), would bring up directions in Google Maps using a specified direction type (e.g. bicycle).
Using the old Google Maps URL parameters you can do,
https://www.google.com/maps/preview?saddr=[insert_from_address_here]&daddr=[insert_to_address_here]&dirflg=[insert_mode_here]
but it doesn't work on mobile.
Using the new Google Maps URL parameters you can do,
https://www.google.com/maps/dir/[customer address]/[our address]/am=t/
which does work on mobile but I don't know how to specify direction type.
From the Google Forum itself, try this on your URL if this works.
Car /data=!4m2!4m1!3e0
Bicycling /data=!4m2!4m1!3e1
Walking /data=!4m2!4m1!3e2
Public Transit /data=!4m2!4m1!3e3
Airplane /data=!4m2!4m1!3e4
For example
https://www.google.com/maps/dir/747+Howard+St,+San+Francisco,+CA/55+Music+Concourse+Dr,+San+Francisco,+CA/data=!4m2!4m1!3e3

Android: Automatic User Locatio

I am working on the developement of an android app. I need to locate the user without displaying the map (only the name of his location ei New york, USA)
I work using Eclipse SDK.
Is there a way to do it?
Thanks :)
Ps: I am new to android
Android API Maps
In the API documentation it shows you step by step how to get started on this
type of application.
How to get started
One thing you have to remember is that the user must enable
the GPS to get current location
Since you explained in comments that you already know how to get the Location, and thus the latitude and longitude, you can resolve it to an address using Android's GeoCoder class, with its getFromLocation(double,double,int) method.

How to determine if lat long coordinates are on a road with Google Maps API v2

I have used Google geo address and using lat/long have got the address. How do I determine if I am on road on not? Basically hit-test for road? I am currently using location manager for lat/long and the GeoAddress is same for on road and next to road.
Final Solution
Use reverse geocoding via the Google Geocoding API.
The term geocoding generally refers to translating a human-readable
address into a location on a map. The process of doing the converse,
translating a location on the map into a human-readable address, is
known as reverse geocoding.
The Geocoding API supports reverse geocoding directly using the latlng
parameter. For example, the following query contains the
latitude/longitude value for a location in Brooklyn:
http://maps.googleapis.com/maps/api/geocode/json?latlng=40.714224,-73.961452&sensor=true_or_false
The docs explain how to interpret the json results but StackOverflow has various answers addressing more efficient ways to parse the data.

Possible Solutions
Getting the nearest street/road coordinates in android - the answer to this question may point you in the right direction.
You can use directions api directly: http://maps.googleapis.com/maps/api/directions/json?origin=51,19&destination=51,19&sensor=false
Could you use the API to find directions which would then provide the closest road?

See fiddle.
It can be done so much easier with OSRM (nearest) webservice. Make a GET request like:
const url = '//router.project-osrm.org/nearest/v1/driving/';
fetch(url + coord.lon + ',' + coord.lat).then(function(response) {
return response.json();
}).then(function(json) {
if (json.code === 'Ok') {
console.info(json.waypoints[0].location);
}
});
Which is a road/street coordinate.

Starting Google Maps App with provided location and marker

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
