Im sorry its not clear as to what you asking here can you please explain this in more detail as to what your trying to achieve please.
What we are trying to achieve is to get the actual user location and put it on a field. Example: the user is on the street and are going to visit a contact. So we get the location of the user and put it on a field, to control where the user have been.
Is there a way to get this location?
Totally understand. So currently you cannot do this within the mobile application that Oracle provides on Android, Blackberry, and IOS. To do something like this you will really need to create a Custom Mobile application that has something that takes the current mobile GPS Location and then pops the address record to get the user to confirm the address details before its is submitted. I have looked around on Marketplace and there doesn't look to be an application currently that can do this im sorry.
