Declare Your recever Class into the ManifestFile. by Giving Properintent Filter   android.provider.Telephony.SMS_RECEIVED

Define the Permissions    android.permission.SEND_SMS
                                         android.permission.RECEIVE_SMS


In to The Layout Section main.xml


<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
