body: <p>Just checking out Android development very superficially, and it seems that most everyone is working in Java. Yet</p>
  
  <blockquote>
    <p>Android includes a set of C/C++
    libraries used by various components
    of the Android system. These
    capabilities are exposed to developers
    through the Android application
    framework.</p>

  <p>does this mean that, in Android applications, Java is used and C++ is used:</p>
  
  <ul>
  <li>sometimes?</li>
  <li>a lot?</li>
  <li>almost never?</li>
  <li>Never: you cannot use it for applications?</li>
  </ul>
