E 'stato possibile inviare SMS Flash (che è il termine per SMS di classe 0) prima di Android 2.2. Google ha rimosso l'API sendRawPdu, quindi anche se si utilizzava il reflection, non sarebbe possibile farlo.
Ecco come ho fatto in precedenza (questo è stato testato su Android 1.6 e lavorato)
private void sendSms(String phone, String sms) {
if ((phone == null) || (sms == null) || (phone.length() == 0)
|| (sms.length() == 0)) {
String message = "Phone or message empty!!!";
Toast notification = Toast.makeText(getBaseContext(), message,
Toast.LENGTH_SHORT);
notification.show();
return;
}
// SecurityManager oldSM = System.getSecurityManager();
// MySecurityManager newSM = new MySecurityManager();
// System.setSecurityManager(newSM);
// ServiceManager.getService("isms")
// ServiceManager.getService("isms");
SmsManager m = SmsManager.getDefault();
PendingIntent sentIntent = PendingIntent
.getBroadcast(this, 0, new Intent(
MessageStatusReceiver_MESSAGE_STATUS_RECEIVED_ACTION),
0);
PendingIntent deliveryIntent = PendingIntent.getBroadcast(this, 0,
new Intent(SmsReceiverService_MESSAGE_SENT_ACTION), 0);
// String sms = "Message self-destroyed!!!";
// String phone = "93634096";
long NOW = System.currentTimeMillis();
String time = String.valueOf(NOW);
// // m.sendTextMessage(phone, null, sms, sentIntent, deliveryIntent);
// working // m.sendTextMessage(phone, null, sms, null, null);
byte[] bb = new byte[1];
Method m2 = null;
try {
m2 = SmsManager.class.getDeclaredMethod("sendRawPdu",
bb.getClass(), bb.getClass(), PendingIntent.class,
PendingIntent.class);

Ehi, hai idea di cosa significano le altre tre classi?Ho cercato per circa due ore, ma non sono in grado di trovare alcuna cosa. – harshit
