title: Updating Dialog with content
body: <p>I want to display a custom dialog while searching the files in SdCard. The custom dialog will display the files found one at a time. although this will be too quick to see all the files being displayed. I am not sure if it is possible.
   The approach i have thought so far is getting file list using Asynctask. but i couldn't update the dialog with the file names in real time. Has anybody tried this before.
  thanks in advance.</p>
