LocationListener timeout

Question

I am currently using a timer to determine if a location listener has timed out ? The problem is that the gps remains on. I don't know why , is there a method i can override when the locationlistener times out or a more elegant method ?

Answer 1

Consider adding a GPS status listener to your location manager. The status listener is informed when the GPS starts, stops, receives a first fix, or the satellite status (no. of visible satellites, you need at least 4 for a fix) changes.

The listener may look like this:

class GpsStatusListener implements GpsStatus.Listener {

    @Override
    public void onGpsStatusChanged(final int event) {
        switch( event ) {
                        // ...
            break;
        case GpsStatus.GPS_EVENT_STOPPED:
                        // ...
            break;
        case GpsStatus.GPS_EVENT_FIRST_FIX:
                        // ...
            break;
        case GpsStatus.GPS_EVENT_SATELLITE_STATUS:
                        // ...
            break;
        }
    }
}

It is added as follows:

lm.addGpsStatusListener(new GpsStatusListener());

You don't need to remove the location listener when the GPS status changes.

You also can get additional information from the location manager by overriding one of the following methods:

public void onStatusChanged(final String provider, final int status, final Bundle extras) {
    switch( status ) {
    case LocationProvider.AVAILABLE:
                // ...
        break;
    case LocationProvider.OUT_OF_SERVICE:
                // ...
        break;
    case LocationProvider.TEMPORARILY_UNAVAILABLE:
                // ...
        break;
    }
}

@Override
public void onProviderEnabled(final String provider) {
                // ...
}

@Override
public void onProviderDisabled(final String provider) {
                // ...
}
