title: How to recursively scan directories in Android
body: <p>How can I recursively scan directories in Android and display file name(s)? I'm trying to scan, but it's slow (force close or wait). I'm using the <code>FileWalker</code> class given in a separate answer <a href="https://stackoverflow.com/questions/2056221/recursively-list-files-in-java">to this question</a>.</p>
