Question

I’m building an android application which uses gps to locate the user. I have a class called LocationService which extends Service and implements LocationListener. In my activity I have the following code. When I want to turn on the service and listen for locations, I call the startLocationService() method. All this is working fine.

I then put this activity in a tab in a tabhost. Now when I call startLocationService(), nothing happens, the onCreate() method in LocationService is not even called. I checked the “this” reference in the line
Intent i = new Intent(this, LocationService.class);
and it refers to the correct activity, not the TabActivity.

I’m at a loss to explain why LocationService is not being started. I’d appreciate any light anyone can shed on this.

thanks,
Paul

private LocationService service = null;
private ServiceConnection svcConn = new ServiceConnection() {
    public void onServiceConnected(ComponentName className, IBinder binder) {
        service = (LocationService)binder;
        try {
            service.registerCallback(cbListener);
            service.enableProximityPoints();

        } catch (Throwable t) {
            Log.e("MyPath", "Exception in call to registerAccount()", t);
        }
    }
    public void onServiceDisconnected(ComponentName className) {
        service = null;
    }
};



private void startLocationService(){
    Intent i = new Intent(this, LocationService.class);
    bindService(i, svcConn, 0);
    startService(i);
}

Looks like someone else has had a similar problem: http://www.mail-archive.com/[e-mail]/msg08047.html

They solved their problem by moving the service connection up into the TabActivity class.
