title: Snackbar in a transparent activity
body: <p>Was trying to make a snackbar in a transparent <code>Activity</code> and got errors, changed the theme in <code>Manifest</code> to  <strong><em><code>android:theme="@style/Theme.AppCompat"</code></em></strong> now it works fine... Doesn't look good though. Is there a way to make the avtivity transparent and make the snackbar work?</p>
  
  <p>Thanks in advance!</p>
