I want to use this logic and I'm not able to do DataWedge configuration, looks like this scenario doesn't work

//MainActivity.java
package com.motorolasolutions.emdk.sample.dwdemosample;

import android.os.Bundle;
import android.app.Activity;
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.content.IntentFilter;
import android.view.View;
import android.widget.TextView;
import android.widget.Button;

public class MainActivity extends Activity {

    private static final String DATA_STRING_TAG = "com.motorolasolutions.emdk.datawedge.data_string";

  private IntentFilter fltIntentAction ;
  private BroadcastReceiver _newItemsReceiver;

  private int iCount = 0;
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
      

    // Let's set the cursor at the end of any text in the editable text field
        TextView et = (TextView)findViewById(R.id.editbox);
        et.setText("Scan Now!");
       
        final Button btn = (Button)findViewById(R.id.button1);
        btn.setOnClickListener(new View.OnClickListener() {
            public void onClick(View v) {
                // Perform action on click
            iCount++;
            Intent intent = new Intent();
                intent.setAction(getString(R.string.intentAction));
                intent.putExtra(DATA_STRING_TAG, String.format("Test broadcast! #%d", iCount));
                sendBroadcast(intent);
            }
        });
       
       
        _newItemsReceiver = new BroadcastReceiver() {  
      
    @Override 
       public void onReceive(Context context, Intent intent) {
  
    if(intent!=null)
    {
    // get the data from the intent
           String data = intent.getStringExtra(DATA_STRING_TAG);
         
           // let's get our edit box view
            TextView et = (TextView)findViewById(R.id.editbox);
            et.setText(data);
    }
       
    }
        };
       
        fltIntentAction = new IntentFilter(getString(R.string.intentAction));
      
        registerReceiver(_newItemsReceiver, fltIntentAction);
    }
   
    @Override
  protected void onDestroy() {
  super.onDestroy();
  // unregister the notifications
  unregisterReceiver(_newItemsReceiver);
  }
  
   
}
