Need to create a app which shows current location to others

I need to create a app which shows current location to others which who install that application?
1)Is it possible to do such a thing?
2)Can anyone tell me a suggetion to do it ?

[Peter Johnson]

There are already apps in the marketplace that do this kind of thing. Look for phone tracking apps. I have one named Anti DT, which when activated enables me to track my phone either from another copy of Anti DT or from a browser on a PC.

I know how to get current location details from android.But how to manage showing all others location.I need to know a way to show everyone's location to eveyone.So what is the best way?

1) is it good to maintain a centralize database or webservice?

[Tim Moores]

The app will need to contact a central server which can maintain the location of all other users. That would amount to a web service, and it may well use a DB. I don't understand where you see the choice between a DB and a WS - they're complementary.
