 Hi, everyone:
    How can my host machine connect to emulator using socket? In my
application, I need emulator to open a server socket, then host
machine connects to emulator as a client. But when host creates the
socket using "10.0.2.15:xxxxx" (xxxxx is the port which emulator is
listenning), it doesn't work. I think maybe the address"10.0.2.15"
goes wrong. Is it a local address behind the "virtual router" and the
host can't find? If so, how to find a correct IP address of emulator?

/** Called when the activity is first created. */

private LocationProvider locationprovider;

private Miseajour miseajour;

private Socket socket;



public androidtracabilite()

{

miseajour = new Miseajour();

try

{

socket=new Socket("192.168.1.6",3000);

}catch(Exception e)

{

//sb.append("Exception leve");

}

}


@Override

public void onCreate(Bundle tracabilite)

{

super.onCreate(tracabilite);

setContentView(R.layout.main);

String location_context = Context.LOCATION_SERVICE;

locationManager =(LocationManager)getSystemService(location_context);

testProviders();

try{

envoiesocket();

TextView tv = (TextView)findViewById(R.id.myTextView);

StringBuilder sb = new StringBuilder("Enabled Providers:");


List <String> providers= new ArrayList<String>(10);


providers =(ArrayList<String>)locationManager.getProviders(true);


for (String provider : providers)

{

locationManager.requestLocationUpdates(provider,0,0,miseajour);

location=locationManager.getLastKnownLocation(provider);


sb.append("\n\n").append(provider).append(" : ");

if (location != null)

{

double lat = location.getLatitude();

double lng = location.getLongitude();

sb.append(lat).append(" ; ").append(lng);

}

else {

sb.append("No location");


}

}


tv.setText(sb);

return(location);


}//fin de la fonction testprovider


public void envoiesocket() throws Exception

{

System.out.println("Entrer dans la fonction");

TextView tv = (TextView)findViewById(R.id.myTextView);

StringBuilder sb = new StringBuilder("Envoie Socket");



BufferedReader plec = new BufferedReader(new InputStreamReader
(socket.getInputStream()));

PrintWriter pred = new PrintWriter(new BufferedWriter(new
OutputStreamWriter(socket.getOutputStream())),true);


pred.println("envoie de socket");

String read= plec.readLine();

plec.close();

pred.close();

socket.close();

sb.append(read);

tv.setText(sb);

}





Thank you for your help
