You could check the list of satellites available, if none are visible,
I'm guessing that would mean you have lost the signal.
Here's some code that may help:
private TextView locGpsStatus = null ;
private Integer iGpsStatus = -1 ;
.
.
.
// Listener for GPS Status...
private final Listener onGpsStatusChange=new GpsStatus.Listener()
{
public void onGpsStatusChanged(int event)
{
if ( DOLOG ) Log.v("TEST","LocationActivity -
onGpsStatusChange:
onGpsStatusChanged: " + Integer.toString(event)) ;
switch( event )
{
case GpsStatus.GPS_EVENT_STARTED:
locGpsStatus.setText("Started...") ;
iGpsStatus = event ;
break ;
case GpsStatus.GPS_EVENT_SATELLITE_STATUS:
GpsStatus xGpsStatus =
locMgr.getGpsStatus(null) ;
Iterable<GpsSatellite> iSatellites =
xGpsStatus.getSatellites() ;
Iterator<GpsSatellite> it =
iSatellites.iterator() ;
iSats = 0 ;
// Satellite Count
while ( it.hasNext() )
{
iSats++ ;
it.next() ;
GpsSatellite oSat = (GpsSatellite)
it.next() ;
if ( DOLOG )
Log.v("TEST","LocationActivity - onGpsStatusChange:
Satellites: " + oSat.getSnr() ) ;
}
if ( DOLOG ) Log.v("TEST","LocationActivity -
onGpsStatusChange:
Satellites: " + iSats ) ;
break ;
case GpsStatus.GPS_EVENT_FIRST_FIX:
locGpsStatus.setText("First Fix...") ;
iGpsStatus = event ;
break ;
case GpsStatus.GPS_EVENT_STOPPED:
locGpsStatus.setText("Stopped...") ;
iGpsStatus = event ;
break ;
}
}
} ;
