Amigo, desenvolvi um socket/cliente.
Mas ao executar o aplicativo Android se fecha automaticamente.
O que poderia ser ?
java
package servidor;
import java.io.DataInputStream;
import java.io.DataOutputStream;
import java.io.IOException;
import java.net.ServerSocket;
import java.net.Socket;
public class SocketServer {
/**
* @param args
*/
public static void main(String[] args) {
// TODO Auto-generated method stub
try {
ServerSocket serverSocket = new ServerSocket(8101);
Socket socket;
while(true){
System.out.println("Esperando conexão.....");
socket = serverSocket.accept();
System.out.println("Conexão Estabelicida");
DataOutputStream out = new DataOutputStream(socket.getOutputStream());
DataInputStream in = new DataInputStream(socket.getInputStream());
System.out.println("---------->"+in.readUTF());
out.writeBytes("Servidor mac"+in.readUTF());
out.flush();
System.out.println("Mensagem Enviada");
System.out.println("Fechando Conexão");
out.close();
socket.close();
}
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}

dataOutputStream.writeUTF(textoSaida.getText().toString());
String stringLida = dataInputStream.readLine();
textoEntrada.setText(stringLida);
socket.close();

dataOutputStream.close();
} catch (UnknownHostException e) {

} catch (IOException e) {
// TODO Auto-generated catch block

}
});
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.main, menu);
return true;
}
}
