How to know if BlackBerry device has GPS?

Question

I want to know if the device has GPS or not, how could I do that for the devices below v 5.0 ?

Answer 1

Have a look at docs for Location Provider. Try this code on a few devices in different situations and I think it should work:

try {
    LocationProvider lp = LocationProvider.getInstance(null);
    if (lp == null) {
        //Device doesn't currently have GPS enabled
    } else {
        //Device has GPS enabled
    }
} catch (LocationException le) {
     //Device's GPS is currently permanently disabled
}

Answer 2

You have to check if Java ME's JSR 179 is available.
