My android application fetches coordinates of the users current location and send it to my website which has the Ushahidi platform installed. I need to display these coordinates on the ushahidi map. Also the android app fetches coordinates of the new location of the user and sends it to the site, therefore I also need a way to replace the old coordinates of the user with the new ones.
Does Ushahidi have any provisions for this? Is there a clean way to do this?
When you say display the coordinates on the Ushahidi map. What exactly do you mean? Do you want to display the coordinates on the info window?
You could use the API to update the coordinates. https://wiki.ushahidi.com/display/WIKI/Ushahidi+Public+API

I need to show google map to user and then resolve the address on that map.
I wonder what's the recommended approach for best user experience in Android?
The ways I was thinking of is:
Show current location (or default if not permitted). Put a pin at the place where user taps on the map. If tapped again, then just move the pin. Resolve the address where last pin was dropped
Another approach is same to what uber has: show the map with a pin in the center of the viewport pointing to current location. That pin is still in the center and consumes new position when map is moved against it. Address is resolved when map movement stop event received
Disadvantages of #1 is that it might be not obvious for user that pin needs to be placed on the map
Is there a best practice for this? Or a more intuitive way to do this?
Any suggestions?
These tasks need Google Cloud Api And That is paid.

I want to make a android app using google maps.In this app I want to share my location to my friend like a request, Once he accepted my request he will get the route map to my location (previously I shared) and also I want to see his moving path towards my location. Can any one please suggest me how is possible to sharing locations.
I think the best way to control that sharing is using socket.IO
on the device you catch your position then emit your position to the server and on the server side you emit to other devices.
Hope helped you
For sharing locations and showing it on map, you need to do it in following steps
Read your location using android APIs.
Once he accepts your request, read his location and share it to your profile through some API to server & keep on updating location on every changed distance delta or at some time interval and share that too.
Now you have co ordinates of both locations. Use them to fill data to Google Maps API and load map in one of your activity. Whenever you will receive updated location of your friend from your server, update the map and draw path between them using google maps api.
For showing map to your location # your friends side, same thing needs to be done. If your location will also change then you will have to provide your updated location to server timely as mentioned in step 2
What if you send a geo: link to your friend? Like geo:62.0,-7.0 ? That should give the receiver a choice between all his geo-capable apps. Google Maps, OsmAnd, maybe some weather service...
In my application I integrated google map. When the map is opened its getting my current location and getting the peoples locations around me from remote server (with a radius of 5000m). Now what if the user moves the map like left, right, up whatever... I want to take the new locations from server which suits to the map at that moment. But I don't know the best practice for that. I can not possible send a query of each single touch (move) right?
if you need to show makers outside of your radius then you will have to use the maps OnCameraChangeListener and when that fires is when the map has stopped moving so then you know it is time to get new data
I want to add markers on map for my android app. I do know how to do it (overlay items). My question is: Since I am manually putting markers on points(on the map) whose lat/long's I already know, I want to know if there is any way to get the exact latitude and longitude of a place on google map? Right now I am asking my people to go to the particular places and use this ( http://bit.ly/K4fOcy ) app to determine the lat/long of that place and send it to me via e-mail. I use these lat/long values to put markers on my map in the app. But the latitudes and longitudes i get are not accurate. they have around 300-2500m error (on real scale).
Or shall I use the Google Places API? How does it work? What about the places which are not in the Google Places database? How do I exactly mark them on the map? I would be very grateful if someone points me in the right direction.
Thanks
If you are working with establishments that aren't represented in the Google Places API and want to be able to pull coordinates directly from http://maps.google.com/, you simply:
Find the location of interest on the map, using an address or just knowledge of the area
Right-click on the map and select What's here? from the context pop-up menu
The Lat-Lng coordinates will be automatically populated in the search input box and usually, the address will also be displayed in the dynamic side-panel (and very often a Street-View photo).
If you are looking for a way to query for the coordinates, you can use the Geocoderdev-guide service to turn addresses into coordinates.
Have you looked at the geocoding API for google maps? It allows you to pass in an address, and returns a Latitude/Longitude pair in response, there is an accuracy value returned with each response to let you know how close the geocoder was able to resolve the location. https://developers.google.com/maps/documentation/geocoding/
I was wondering how I can channel or simulate Google Maps just in the sense of a user types in a location in text, such as a restaurant name and a city name. Then Google suggests 5 or so places they have indexed, and presumably they know the GPS coordinates because Google then puts them on a map. I want to be able to use that feature- not the map, just getting the location.
My goal is for a user to type in a query, 5 options or so to be shown, and if they user chooses one of them, then the GPS coordinates, or a location object, is saved representing that place.
Ideally I could just send the query to Google and steal the results back to my app. Obviously building my own database of locations and an algorithm to suggest them is out of the question.
Thanks for the help and advice in advanced!
Note 1: To clarify, this does NOT involve the current position of the user/device.
Note 2: I looked at the Google Maps add-on API, but it looks like that is for a visual map, not the querying a location part. You are already supposed to know your location, and it will map it.
Use geocoder.getFromLocationName, you get back a list of Address objects, in those objects you will find all the information you need about the location.
To test this on the simulator you need an image with the Google APIs included. In a device should be fine if you have the market installed.
