About Android socket programming implemented in two emulators

1. Open Two simulator:

Under Tools located in the command line to the SDK, enter Emulator-data foo to start two emulators.

2. Determine one of the servers as a server:

Need to have the Android emulator as a server to detect if two emulators are normal its command statement: ADB devices after you set up one of the servers. Its command-line statement is: The name of the telnet localhost + emulator, for example: Telnet localhost 5554: "5554" is the name of the emulator. After displaying "OK", proceed to the following statement: Redir add tcp:8192:8191

3. Execute the server-side and client code:

Server

public Class Server extends Activity {

public static final String ServerIP = "10.0.2.15";//This address is not actually used

public static final int serverport = 8191; Note that this is related to the configuration of the above redirection.

@Override

public void OnCreate (Bundle savedinstancestate) {

Super.oncreate (savedinstancestate);

Setcontentview (R.layout.main);

try {

ServerSocket serversocket = new ServerSocket (serverport);

while (true) {

Socket client = Serversocket.accept ();

System.out.println ("s:receiving...\n" +client.getinetaddress ());

Client.getinetaddress ();

}

}catch (Exception e) {

System.out.println ("S:error");

E.printstacktrace ();

}

}

}

Client

public class Client extends Activity {

@Override

public void OnCreate (Bundle savedinstancestate) {

Super.oncreate (savedinstancestate);

Setcontentview (R.layout.main);

try {

Socket socket = new Socket ("10.0.2.2", 8192);//Note this is also related to the configuration of the above redirection. And the address here must be 10.0.2.2.

} catch (Unknownhostexception e) {

TODO auto-generated Catch block

E.printstacktrace ();

} catch (IOException e) {

TODO auto-generated Catch block

E.printstacktrace ();

}

}

}

Note: The androidmanifest.xml of two programs must add the following permissions:
