How could I get and use the number of satellites before starting location tracking?

For example I want to start location tracking only when there are min X satellites in use.

See the answer I gave you to your other question - http://stackoverflow.com/questions/3551697/how-to-measure-gps-signal-strength-on-android/3551743#3551743.

Basically, LocationManager.getGpsStatus().getSatellites().

And again, personally I don't think that going on this level is a good idea for a location-based app, unless you specifically need to do something with the satellite data.
