You can permit a BlackBerry® device application to obtain GPS information while a BlackBerry device user is on a phone call.

1. Import the following classes:
   • javax.microedition.location.LocationProvider
   • javax.microedition.location.Criteria
2. Create an instance of the Criteria class.

   Criteria criteria = new Criteria();
   

3. Configure the Criteria object to obtain GPS information without using a wireless network.
4. Invoke Criteria.setCostAllowed() using the Boolean value of false as a parameter to configure that a BlackBerry device cannot incur any costs.

   criteria.setCostAllowed(false);
   

5. Invoke the LocationProvider.getInstance() method using a Criteria object as a parameter that you configure to obtain GPS information without using a wireless network. Assign the value that the method returns to a LocationProvider variable.

   LocationProvider provider = LocationProvider.getInstance(criteria);
