• This week we added navigation to our Android app; for more see the course site http://bit.ly/androidjava #
• Topics covered: Loading avatars using Thread or AsyncTask, loading tweets with AsyncTask, adding Menu, and posting new tweets #AndroidJava #
• AsyncTask makes UI threading straightforward, nice! Javadoc http://bit.ly/aZ41Di and an article http://bit.ly/bIqbQ5 #
• The course instructor notes that using AsyncTask also keeps code cleaner and more reusable; it's made of WIN! #
• #AndroidJava tip: Toast.makeText pops up a quick, non-modal notification (just don't forget to call show!) http://bit.ly/dphiLR #
