title: Android : Dialog: should I hide or dismiss
body: <p>I'm playing around with Dialog to create some quick views in my app (like login enter name etc)</p>
  <p>and I'm wandering what is better: hide or dismiss.</p>
  <p>I know what they both do but I keep wandering if it is better to just hide a Dialog and show it again when I need or to dismiss it and recreate it.</p>
  <p>my Dialogs are small and are actually static in my code so as such I don't hold tons of instances.</p>
  <p>So can somebody give me the pros and cons of using hide over dismiss.</p>
