I didn't too. Any particular reason to use Asyntasks instead of threads? I
don't if it has any benefit.

 Yes, everything is ok.

 Anyway, I didnt know that I cant use long operations inside oncreate
 method. I'm trying to use asyntask or thread to do these things.

 Thanks

It simplifies running a background operation while interacting with the main

The toast will only show after your code returns from onCreate, which it

 Many thanks,
 I'm using now Asyntask and I'm using Toast in PreExecute and
 PostExecute methods.

 Your code, as far as I can tell, runs inside onCreate. Android UI
framework
 is designed so that it expects callbacks like onCreate and others to
return
 control to Android within a reasonable amount of time.

 Your code prevents Android from doing things in the UI, including showing
 toasts (or dialogs), because it ties up the UI thread with your work
 function.

 Study Application fundamentals in the SDK documentation, specifically
 information about threads, it does a good job at explaining this.

 To run networking code, create a background thread. An easy way to do it
is
 to use AsyncTask, a generic class provided by the Android framework.

  I dont understand what do you say Kostya
  I've installed the app in the devices but the Toast doesnt shows.
  The complete Oncreate is:

  public void onCreate(Bundle savedInstanceState) {
  super.onCreate(savedInstanceState);
  setContentView(R.layout.main);
  Log.d(PRUEBA, COMENZAMOS EL PROGRAMA);

  // Toast.makeText(ssh.this, ,
  Toast.LENGTH_SHORT).show();

  InetAddress pp;
  InetAddress direccionMaquinon;

  if (pruebaPing(221.221.221.2)){
  Log.d(PRUEBA,No llega despues de comprobar el primer ping.
  Hay que mandar paquete);
  Toast.makeText(this, ,
  Toast.LENGTH_SHORT).show();

  wakeonLan();
  Toast.makeText(this, ,
  Toast.LENGTH_SHORT).show();
  mandarSsh();
  }else{
  Log.d(PRUEBA,slllega);
  mandarSsh();
  }
  }
  public void wakeonLan (){

  try {
  Toast.makeText(this, Nsdfsdfdsfd paquete magico en...,
  Toast.LENGTH_LONG).show();

  final int PORT = 9;
  String ipStr = 221.x
  ...
  ...

  The toast will only show after your code returns from onCreate, which
it
  should.

   Hi again,
   I can't understand nothing.
   I'm trying to execute a simple toast when the activity create but
   doenn't show anything:

   code:

   public class ssh extends Activity {
   /** Called when the activity is first created. */
   public static final int PORT = 9;

   @Override
   public void onCreate(Bundle savedInstanceState) {
   super.onCreate(savedInstanceState);
   setContentView(R.layout.main);
   Log.d(PRUEBA, COMENZAMOS EL PROGRAMA);

   Toast.makeText(ssh.this, ,
   Toast.LENGTH_SHORT).show();
   ...

   OK. Try calling Toast from the UI thread. You can use Handler for
 this.

Yes I'm sure.

public void wakeonLan (){
..

while (pruebaPing(maquina)){
//MIENTR=AS NO RESPONDA A PING. DORMIMOS 6 SEGUNDOS EL
PROCESO

Thread.sleep(6000);
contadorDormido=contadorDormido+6;
Log.d(PRUEBA, No responde a ping despues de mandar el
paquete magico en... + contadorDormido);
Toast.makeText(getApplicationContext(), No responde a
ping despues de mandar el paquete magico en... +
contadorDormido,
Toast.LENGTH_SHORT).show();
Toast.makeText(this, No esponde a ping despues de
mandar el paquete magico en... + contadorDormido,
Toast.LENGTH_SHORT).show();
Toast.makeText(ssh.this.getApplicationContext(), No
responde a ping despues de mandar el paquete magico en... +
contadorDormido, Toast.LENGTH_SHORT).show();


And I can see the logcat

Please any help?
Many thanks

Are you sure this code actually runs, and calls Toast? Add
logcat
   printouts
just before Toast to make sure.
