Starting second activity with Android result

The basic model for passing information between Acitivities is this, according to android documentation :

  Intent intent = new Intent(this, OutraActivity.class);
  EditText editText = (EditText) findViewById(R.id.meuEditText);
  String message = editText.getText().toString();
  intent.putExtra("mensagem", message);
  startActivity(intent);

And to get the OutraActivity.class :

Intent intent = getIntent();
String message = intent.getStringExtra("mensagem");

There are more examples in the documentation, enjoy and check it out, it is in English but it is very ditático.
