Dear All,

There will be no lecture on Wednesday Sep 13, but TAs for the
class will walk you through the installations of Android Studio 3.0,
creation of Android emulators, and programming a simple "Hello World"
application. 

If you are familiar with these topics, you don't need to come to class.
If this is your first time with Android Studio, however, I advise
that you show up at the regular room and time.

Thank you,

--Sergey
