1. updating proximity alerts

Hi all,

I have a problem with updating proximity Alerts.
Some times the emulator crashes when I try to update the registration for an 
proximity alert.
The relevant code for updating is as follows:

mLocationManager.removeProximityAlert(i);


                mLocationManager.addProximityAlert(
                                (double)place.getLatitude() / 1E6,
                                (double)place.getLongitude() / 1E6,
                                
(float)((PlaceLocationDetector)place.getDetector()).getRange(),
                                10000000,               //FIXME change 
expiration to -1 when sdk is fixed
                                i);
                mRegisteredProximityAlerts.put(place.getRowID(), i);

The resulting stack dump:

DEBUG/LocationManager(715): addProximityAlert: latitude = 37.461734, longitude 
= -122.144394, radius = 305.0, expiration = 10000000, intent = Intent {

Any ideas on what might go wrong here?
Is it a known problem or are we doing something wrong here?

thanks,

2. Network interface behaving erratically

Hi!

I am working on a Peer to Peer application. When I run this
application in debug mode with emulator attached, the application and
send and receive packets, however, when I run the application in
Standalone mode, by simply launching it from the emulator. Sockets
dont give any error, but they do not even send packet outside the
emulator.

Am I missing on something. Kindly suggest.

Regards
Nitin
