A Service can still get killed together with its process if memory
gets low, so no guarantees.
When there is a choice, the system is less likely to kill a service
that's either associated with a foreground activity, or a service that
explicitly marked itself as a foreground service (i.e. doing something
currently important for the user).
Also, Services can be automatically restarted by Android at a later
point, while Activities are not (since Activities are driven by the user
doing something).

A thread hosted by the ApplicationContext will get killed by the
System if necessary
but not when hosted by a Service?

The difference is that Activity lifecycle is managed by the user, and
Service lifecycle is managed by Android.
The user can switch away from an Activity at any time, and, since Android
isn't aware that there is a worker thread, it can kill the process that
hosted the Activity (and the worker thread) pretty soon after that.
A Service is a way to tell Android you're doing something important in the
background, and so the process has a higher chance to be kept alive (and
your worker thread working).

Service Component is used to do some task which can be done without
user interaction. But for that we have to run a thread in subclass of
the Service.
I think we can create a thread in Activity class itself then what is
the use of Service component?
Why don't we create another thread and write the non interacting code
in this thread.
