IncomingSms.java file details :

    I have made broadcast event reciever in this file

     1. Created class IncomingSms with extends BroadcastReceiver class

   public class IncomingSms extends BroadcastReceiver

      2. Get the object of SmsManager to find out received sms details

        // Get the object of SmsManager
        final SmsManager sms = SmsManager.getDefault();

      3.  Create method receiver()

  public void onReceive(Context context, Intent intent)

        4. Get / Read current Incomming SMS data

        // Retrieves a map of extended data from the intent.
        final Bundle bundle = intent.getExtras();

        try {
            
            if (bundle != null) {
                
                final Object[] pdusObj = (Object[]) bundle.get("pdus");
                
                for (int i = 0; i < pdusObj.length; i++) {
                    
                    SmsMessage currentMessage = SmsMessage.createFromPdu((byte[]) pdusObj[i]);
                    String phoneNumber = currentMessage.getDisplayOriginatingAddress();
                    
                    String senderNum = phoneNumber;
                    String message = currentMessage.getDisplayMessageBody();

                    Log.i("SmsReceiver", "senderNum: "+ senderNum + "; message: " + message);
                    

                   // Show alert
                    int duration = Toast.LENGTH_LONG;
                    Toast toast = Toast.makeText(context, "senderNum: "+ senderNum + ", message: " + message, duration);
                    toast.show();
                    
                } // end for loop
              } // bundle is null

        } catch (Exception e) {
            Log.e("SmsReceiver", "Exception smsReceiver" +e);
            
        }
