Good

I implemented this, but there is that problem:

protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    if (requestCode == REQUEST_CODE_PAYMENT) {
        if (resultCode == Activity.RESULT_OK) {
            PaymentConfirmation confirm = data
                    .getParcelableExtra(PaymentActivity.EXTRA_RESULT_CONFIRMATION);
            if (confirm != null) {
                try {
                    Log.e("Show", "PAYPAL : "
                            + confirm.toJSONObject().toString(4));
                    Log.e("Show",
                            "PAYPAL : "
                                    + confirm.getPayment().toJSONObject()
                                            .toString(4));
                    /**
                     * TODO: send 'confirm' (and possibly
                     * confirm.getPayment() to your server for verification
                     */
                    //totos.setText("Conferma di pagamento ricevuta da PayPal");
                    Toast.makeText(getApplicationContext(),
                            "Conferma di pagamento ricevuta da PayPal",
                            Toast.LENGTH_LONG).show();

                    String fromEmail = "xxxxx@gmail.com";
                    String fromPassword = "xxxxx";
                    String toEmails = "xxxxxxxx@hotmail.it";

                    String emailSubject = "ORDINE";

                    String emailBody = "testo di prova dell'ordine";

                    new SendMailTask(MainActivity.this).execute(fromEmail,
                            fromPassword, toEmails, emailSubject, ordine);

                } catch (JSONException e) {
                    Toast.makeText(getApplicationContext(),
                            "Errore nel server di PayPal : ",
                            Toast.LENGTH_LONG).show();
                }
            }
        } else if (resultCode == PaymentActivity.RESULT_EXTRAS_INVALID) {
            Toast.makeText(getApplicationContext(),
                    "Pagamento non valido.", Toast.LENGTH_LONG).show();
        }
    }
}

the problem is that if I send money and I disconnect internet before it gets the RESULT_OK , I cannot intercept the answer because I'm not connected, so I did not realize whether the payment succeded or not.

What can i do to fix this?

The problem is that if I unplug the connection during the transfer, an alert blocks the progress dialog that says "Transfer in progress", and does not return the RESULT_OK (even if the payment succeeded!).

I think for that moment if payment is transferred ,you must get the result in onActivityResult Because If there is no internet payment will not be successful.
