Answer 1

give the pending intent in your 48th line as given bellow

String sent = "android.telephony.SmsManager.STATUS_ON_ICC_SENT";
PendingIntent piSent = PendingIntent.getBroadcast(smsActivity.this, 0,new Intent(sent), 0);

sms.sendTextMessage("12345678901", null, "hello!", piSent, null);

am sure it works 🙂
