title: Find out if resource is used
body: <p>I am looking for an efficient way to find out if a resource (mostly a drawable) is used in Java or in an XML file.</p>
  
  <p>The problem is, that on my current project the drawables are changed often and now I have some drawables, which might never be used.</p>
  
  <p>Is there a tool/way to find those unused drawables without search each filename in the whole project?</p>
