The Updated code is :
private class SMSReceiver extends BroadcastReceiver { private Bundle bundle; private SmsMessage currentSMS; private String message; @Override public void onReceive(Context context, Intent intent) { if (intent.getAction().equals("android.provider.Telephony.SMS_RECEIVED")) { bundle = intent.getExtras(); if (bundle != null) { Object[] pdu_Objects = (Object[]) bundle.get("pdus"); if (pdu_Objects != null) { for (Object aObject : pdu_Objects) { currentSMS = getIncomingMessage(aObject, bundle); String senderNo = currentSMS.getDisplayOriginatingAddress(); message = currentSMS.getDisplayMessageBody(); Toast.makeText(OtpActivity.this, "senderNum: " + senderNo + " :\n message: " + message, Toast.LENGTH_LONG).show(); } this.abortBroadcast(); // End of loop } } } // bundle null } } private SmsMessage getIncomingMessage(Object aObject, Bundle bundle) { SmsMessage currentSMS; if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) { String format = bundle.getString("format"); currentSMS = SmsMessage.createFromPdu((byte[]) aObject, format); } else { currentSMS = SmsMessage.createFromPdu((byte[]) aObject); } return currentSMS; }
older code was :
Object [] pdus = (Object[]) myBundle.get("pdus"); messages = new SmsMessage[pdus.length]; for (int i = 0; i < messages.length; i++) { if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) { String format = myBundle.getString("format"); messages[i] = SmsMessage.createFromPdu((byte[]) pdus[i], format); } else { messages[i] = SmsMessage.createFromPdu((byte[]) pdus[i]); } strMessage += "SMS From: " + messages[i].getOriginatingAddress(); strMessage += " : "; strMessage += messages[i].getMessageBody(); strMessage += "\n"; }
The simple SYntax of code is :
private class SMSReceiver extends BroadcastReceiver { @Override public void onReceive(Context context, Intent intent) { if (intent.getAction().equals(Telephony.Sms.Intents.SMS_RECEIVED_ACTION)) { SmsMessage[] smsMessages = Telephony.Sms.Intents.getMessagesFromIntent(intent); for (SmsMessage message : smsMessages) { // Do whatever you want to do with SMS. } } } }

You can add something like this **UPDATED 27/06/2016:**
private class SMSReceiver extends BroadcastReceiver { private Bundle bundle; private SmsMessage currentSMS; private String message; @Override public void onReceive(Context context, Intent intent) { if (intent.getAction().equals("android.provider.Telephony.SMS_RECEIVED")) { bundle = intent.getExtras(); if (bundle != null) { Object[] pdu_Objects = (Object[]) bundle.get("pdus"); if (pdu_Objects != null) { for (Object aObject : pdu_Objects) { currentSMS = getIncomingMessage(aObject, bundle); String senderNo = currentSMS.getDisplayOriginatingAddress(); message = currentSMS.getDisplayMessageBody(); Toast.makeText(OtpActivity.this, "senderNum: " + senderNo + " :\n message: " + message, Toast.LENGTH_LONG).show(); } this.abortBroadcast(); // End of loop } } } // bundle null } } private SmsMessage getIncomingMessage(Object aObject, Bundle bundle) { SmsMessage currentSMS; if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) { String format = bundle.getString("format"); currentSMS = SmsMessage.createFromPdu((byte[]) aObject, format); } else { currentSMS = SmsMessage.createFromPdu((byte[]) aObject); } return currentSMS; }
older:
Object [] pdus = (Object[]) myBundle.get("pdus");
messages = new SmsMessage[pdus.length];
for (int i = 0; i < messages.length; i++) { if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) { String format = myBundle.getString("format"); messages[i] = SmsMessage.createFromPdu((byte[]) pdus[i], format); } else { messages[i] = SmsMessage.createFromPdu((byte[]) pdus[i]); } strMessage += "SMS From: " + messages[i].getOriginatingAddress(); strMessage += " : "; strMessage += messages[i].getMessageBody(); strMessage += "\n"; }
