title: Broadcast Sender and Receiver pair
body: <p>On one file I am sending the broardcast.</p>
  
  <pre><code>Intent Message1 = new Intent(this, MyClass.class);
  Message1.putExtra("hello", false);
  sendBroadcast(Message1);
  </code></pre>
  
  <p>On the receiver Side, I have </p>
  
  <pre><code>myreceiver extends BroadcastReceiver {
      public void onReceive(Context context, Intent intent) {
          if (intent.getExtra.equals("hello") {
              [...]
          }
      }
      [...]
  }
  </code></pre>
  
  <p>The key is the receiever has to have intent's Extra match to the broadcaster's "hello" in order to proceed.  Can I do like that?</p>
