GPS Location Tutorial

[trope]

Can you please tell me what tutorials I would need to study to learn how to make the following program:


CLICK HERE TO FIND CLOSEST GROCERY STORE

Results:

Stop and Shop - 1.2 Miles - Click for directions


I realize that simple program incorporates a lot of functionality, however, I have to begin somewhere!

Thanks.

Hi.

Here's a suggestion: http://www.b4x.com/forum/basic4andr...smdroid-mapview-b4a-tutorial-4.html#post93131.

That may be more elaborate than you wanted but will enable your user to:

• Automatically set their location using GPS.
• Pan and zoom a map to manually set a location.

Once you have a location you'll find HttpUtils can be used to query a remote webservice for the nearest stores.
(Presumably you have a webservice in mind?)

hey,

have been trying to do the same..and have it working pretty good too..

1:use locationmanager to get current location.
2:get lat lon from location manager
3:do a distance calculation to the store lat lon
4:use the follwing code to start navigation

///this code was found on these forums and works beautifully
Sub ShowNavigation (Latitude As String,Longitude As String)
'google place, just show map
Dim mapIntent As Intent
Dim geoURI As String
geoURI="google.navigation:q=" & Latitude & "," & Longitude
mapIntent.Initialize(mapIntent.ACTION_VIEW,geoURI)
mapIntent.SetComponent("googlemaps")
StartActivity(mapIntent)
End Sub

hope this helps...
