  @Override
  protected void onCreate(Bundle savedInstanceState) {
      super.onCreate(savedInstanceState);
      setContentView(R.layout.activity_esm_famil);
  }
  
  @Override
  public boolean onCreateOptionsMenu(Menu menu) {
      // Inflate the menu; this adds items to the action bar if it is present.
      getMenuInflater().inflate(R.menu.esm_famil, menu);
      return true;
  }
  
  //handler for sendtoserver
  public void sendToServer(View view){
  
      ...
  
  
      String host = "192.168.1.7";
      int port = 8888;
      try{
          Socket s = new Socket(host, port);
          Writer out = new OutputStreamWriter(s.getOutputStream());
          out.write(data + "\n");
          out.flush();
          s.close();
      }catch (UnknownHostException ex) {
          ex.printStackTrace();
      }catch(IOException ex){
