Can't pass a var to an other activity

I have a problem to pass a var to an other activity: This is where I take the variable:

public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.scelta);               
    // l'intent di questa activity
    Intent intent=getIntent();
    String pkg = getPackageName();
    //prendiamo i dati         
    nome=intent.getStringExtra(pkg+".myNome");

This is where I change activity:

public void checkout (View v){
    // l'intent di questa activity
    Intent intent;
    String pkg=getPackageName();
    intent=new Intent(getApplicationContext(), checkout.class);
    //li reinseriamo nell'intent
    intent.putExtra(pkg+".myNome", nome);
    intent.putExtra(pkg+".myId", id);

    Log.d(TAG,"questo è il nome che va ad instargh:"+nome);
    startActivity(intent);
}

thanks to log I am certain that "nome" have the value that i want. This is where i take "myNome"

public class checkout<targhe> extends ListActivity
{String sId=null;
@Override
public void onCreate(Bundle savedInstanceState){
    super.onCreate(savedInstanceState);
    setContentView(R.layout.checkout); 
    Intent intent;
    String pkg=getPackageName();                    
    intent=new Intent(getApplicationContext(), scelta.class);
    nome=intent.getStringExtra(pkg+".myNome");
    Log.D(TAG,"name"+nome);}

with this Log "nome" is always null. I don't understand why I can't take myNome from the intent :/

this is not all the code,but the parts the is important for my problem.

Some one can help me?

You should use getIntent().getStringExtra(pkg+".myNome");

In checkout, try changing

Intent intent;                  
intent=new Intent(getApplicationContext(), scelta.class);

to 

Intent intent = getIntent();

And see if that works.

Also, are both of your Activitys in the same package? If not, getPackageName() will be different in both.

Carefully see your code

in checkout Activity you have written

nome=intent.getStringExtra(pkg+".myNome");

Replace above line of code with following

nome=getIntent().getStringExtra(pkg+".myNome");
