title: How do I permit the android browser to download files of a particular extension?
body: <p>I want to have the default android browser be able to download files of a particular file extension, .xyz, for example.</p>
  
  <p>Without installing Astro (or some other file manager), users will get the error "Cannot download. The content is not supported on this phone". Installing the Astro application allows the android browser to download any file to the sdcard.</p>
  
  <p>How does it do that? I don't want users of my app to have to download Astro, but rather, just let the OS or browser know that it's okay to download files with the extension .xyz, because my app will handle them.</p>
