title: Pass data from Service to Activity
body: <p>I have the service that runs itself (service starts automatically). <br /></p>
  
  <p>And I have the Activity. <br />
  In this Activity button starts the method <code>DoIt()</code>:</p>
  
  <pre><code>Button.setOnClickListener(new OnClickListener() {
      public void onClick(View v) {
        DoIt();
      }
  });
  </code></pre>
  
  <p>Some data is written to the variable <code>data</code> in my service when I push the button and method works.  <br />
  I can see <code>data</code> in Log:</p>
  
  <pre><code>public String getMessage(String data) {
  ... 
  Log.d(TAG, "Our Data: " + data);
  return date;
  ...   
  </code></pre>
  
  <p><b>But how can I see this data in my Activity (under the button) by pushing the button?</b> <br />
  Thanks.</p>
