Just double check to be safe. Will accountName ever be null or empty string in
special situation like no account is available?

[Lambros, 2016/10/07 20:46:22]

This is OK - onAccountSelected() should never be called with a null account. If
there are no accounts, we show a warning dialog then close the Activity.

Acknowledged.
