Re:: [android-developers] Re: Singletons in Android .... Final solution?

Same thread in a different process?

Is that some kind of metaphor I'm not able to understand?

As far as "a field becoming uninitialized" - you haven't shown that, only your lack of understanding of Android fundamentals, and an irrational desire to insist on it.

I know!  I know!  Different process, different class loaders,
(...oddly, might be the same thread)

The point of this whole thread, I believe, is that it is not safe to
put stuff in to static fields of the application.  They will not be
there when you get back.  Among the things that it is not safe to do,
is to "initialize" the static field with some value and then assume
that the field will continue to have that value.  From the point of
view of your application/task the field has become uninitialized.

I completely agree that this might not be a bug.  It is outright
documented to happen in an Activity.  It is a little surprising, in
the activity, though...
