I have an instance variable in a singleton class which I'm using in all the
app. It's basically a global configuration parameter.
I initialize it in the first (launcher) screen of the app. The app will not
continue without this initialization (where it's sure that the variable is
not null).
Thanks all!

You are not using the singleton pattern properly.
You should access it with a getInstance method which will initialize it if
it is null.

Because e.g. the system kills the app while it's in the background, and
tries to restart it in the last screen - since the variable is only

Nope, you can't do it because of the security risks.
However, there are a lot of apps that run on top of the lock screen using
some sort of trickery.
You could also do it in a Custom ROM because you could make it part of the
system.

No.

No, no, the question is not about the singleton itself. It's about an
