Singletons, manager, or utility classes should not be caching a

They can and should if needed or wanted. However ...
At most, they should be caching an Application, to prevent
people from accidentally caching short-lived Contexts (e.g., Activity,
Service).
... I'd further qualify that as "... a cached Context (if needed) should
be an Application object reference, rather than a local, short-lived
Context".
I used to use lines like TreKing's "Never use
getApplicationContext()", but I've tried to be a tad more nuanced in
recent months.
Good.
Broad statements like that always remind me that "the difference between
theory and practice is that, in theory, there is no difference".
That being said, there is no question in my mind that,
in a support board like this, getApplicationContext() is a major code
smell. Most times, it is not needed, and can sometimes give erroneous
results.
Right. Let's just not throw the baby out with the bath water :)
