How can I check the current status of the GPS receiver?

Question

How can I check the current status of the GPS receiver? I already checked the LocationListener onStatusChanged method but somehow it seems that is not working,

Answer 1

Ok, so let's try a combination of all the answers and updates so far and do something like this:

• Add the ACCESS_FINE_LOCATION permission to your manifest
• Get an instance of the system LocationManager
• Create a GpsStatus.Listener that reacts to GPS_EVENT_SATELLITE_STATUS
• Register the listener with LocationManager with addGpsStatusListener

The GPS listener could be something like this:

GpsStatus.Listener listener = new GpsStatus.Listener() {
    void onGpsStatusChanged(int event) {
        if (event == GPS_EVENT_SATELLITE_STATUS) {
            GpsStatus status = mLocManager.getGpsStatus(null);
            Iterable sats = status.getSatellites();
            // Check number of satellites in list to determine fix state
        }
    }
}

The APIs are a bit unclear about when and what GPS and satellite information is given, but I think an idea would be to look at how many satellites are available. If it's below three, then you can't have a fix. If it's more, then you should have a fix.

Trial and error is probably the way to go to determine how often Android reports satellite info, and what info each GpsSatellite object contains.
