how much latitude and longitude accuracy can be used in J2ME ?

[maaz4]

Criteria cr = new Criteria();
// Required Accuracy is set to 100 Meters
cr.setHorizontalAccuracy(100);
LocationProvider provider = LocationProvider.getInstance(cr);


what is the minimum meters that can be used for this accuracy function ? Can I use 5 meters for more accuracy ?

I'd say that this is probably unnecessary to use at all. It will not give you more accuracy, but it will give a hint to the system in choosing a location provider (e.g., to choose between whether it uses network positioning or a GPS, depending on what the device supports), but doesn't really guarantee anything.

If you ignore it (do not use/set this at all, but leave at default), you will probably get the most accurate position that the device can handle (maximum/best accuracy, whatever it is). You won't really know how accurate the position really is (or isn't, as it may be). In other words, when you set the value, you just present a developer's wish/desire to the system, but whether it actually has any impact on the results is implementation-dependent (and as far as I know, no Nokia documentation publishes what kind of logic Nokia's implementations use in this respect).

Thanks for your quick reply sir.

so do you mean that i should keep it like this ?

cr.setHorizontalAccuracy();

You don't need to use cr/Criteria() at all, is my opinion: LocationProvider provider = LocationProvider.getInstance();

can you please help me to find that link in Nokia Documentation ?

I am sorry as I am getting addicted to forums.
