Programs should chat with each other. Do your programs do that? What, you don't know? See - we need change, instantly.
Android has a system-wide log("logcat") - but you only see it in a debugger (a special program for experts).
Actually, they restricted read access to the log in recent Android versions.
That's how bad Google is - they take your priviledges away with software updates.
Think about that. You cannot read the logs on your own phone.
Anyway. So we need something else, and we want to support all the platforms, as usual (Windows/Linux/Mac OS/Android).
How can we make a stable system-wide chat?
The usual idea is to have a dedicated process receiving log lines from processes and saving them. It's a SPOF which is not so good... but it will do for now.
Let's just set up this logging process directly in any JavaX program. We can make it a one-liner!
