Blocking the UI thread will cause Android to force-close your activity
after several seconds, and will confuse and irritate your users up until
that point when they can't figure out why the application is not
responding to
aspects of
the OS, most of the built-in Android apps, and most third-party apps,
allow the users to be rather oblivious to details like where things get
