Titanium Mobile (Android) sample -- save file to sdcard and register to photo gallery.

gistfile1.coffee

        save_button.addEventListener('click', ()->

          if Ti.Filesystem.isExternalStoragePresent
            save_image = Ti.Filesystem.getFile(path).read()
            new_path = Titanium.Filesystem.externalStorageDirectory + Date.now().toString() + ".png"
            f = Ti.Filesystem.getFile(new_path)
            result = f.write(save_image)

            unless result
              return null

            callback_fn = (e)->
              Ti.API.info e 
              if e.uri
                message = L('saved')
              else
                message = L('error')

              alert message
              return

            Ti.Media.Android.scanMediaFiles([new_path], null, callback_fn)

          return
        )

Also I tried using the ApplicationDataDirectory but when I am viewing the image in the gallery it is a blank gray box..Is it because access to ApplicationDataDirectory is restricted to other applications?

Did you ever find the solution for this problem ?
