Toast is a notification widget. The above piece of code will display a
small notification at the near the bottom of your screen that the
"path" has not been set.
In the above example, inside the if (path==""){ }, it would be better
to return rather than continuing.
Please look at
http://code.google.com/android/reference/android/media/MediaPlayer.html
for the list of exceptions that the APIs can throw.
