title: Notify database changes to fragment from Service, Activity, Fragment, etc
body: <p>My app have many fragments, many of them extends from ListFragment and have Adapters for read database (SQLite). My app have only one Activity (for now) and have a Service is binded when the Activity start.</p>
  
  <p>My problem is how to notify to a fragment when are changes in the database from the service or other fragment.</p>
  
  <h2>Example of architecture of my application</h2>
  
  <pre><code>MainActivity
    tabhost
     fragment
       listfragment
       listfragment
     fragment
       fragment
       gridfragment
     fragment
  
  MainService
    comunication_server
      send_data
      receive_data
  </code></pre>
  
  <p>As you can see my application has several fragments, and I want to inform the fragments that the data has changed. or at least launch an internal broadcast can hear by fragments like <a href="http://msdn.microsoft.com/en-us/library/system.componentmodel.inotifypropertychanged.aspx" rel="nofollow">iNotifyPropertyChange .NET C#/WPF</a></p>
