firemonkey location sensor status dont change

Question

my app is showing the location long and lat and it is working well

but when i have to detect the location sensor status like on , of , working , error,... it have some problem

my idea was this code :

  Case LocationSensor1.Sensor.State of
        TSensorState.Added : label5.Text:='2';
        TSensorState.Removed : label5.Text:='3';
        TSensorState.Initializing : label5.Text:='4';
        TSensorState.Ready : label5.Text:='ready';
        TSensorState.NoData : label5.Text:='6';
        TSensorState.AccessDenied : label5.Text:='7';
        TSensorState.Error : label5.Text:='8';
        else label5.Text:='error';
  End;

but when i turn on or off the gps it is ready every time

how can i detect and show the gps sensor status ?

Answer 1

You have to create a class extending the LocationListener class. You will be notified of the GPS status changes by two callback functions : onProviderEnabled, which will be called when the GPS is enabled, and onProviderDisabled when it is disabled.

To register your listener, use ((LocationManager) getApplicationContext().getSystemService(Context.LOCATION_SERVICE)).requestLocationUpdates(LocationManager.GPS_PROVIDER, 1000, 0, myLocationListener); .
