Question

Is there any J2ME API by which i can retrieve the GPS coordinates of current location?

Asked by: Amitabh_Basu

I am trying to create a J2ME application which as a part of solution should be able to send the GPS coordinates of the users current location. However, i am not sure if there is any standard CLDC/MIPD api for J2ME through which this could be made possible. If not what are the other means through which this can be achieved. Any link or sample code which established the solution to the above stated problem will be appreciated.
