Typically, processes aren't expected to do any work when cached, but some apps might have custom features supported by processes that are expected to run while cached.

This quote comes from Android Source Code Document . What is the custom features that can be running in cached processes. As I understand it, cached processes do not contain any running Android component, so does it mean that programs can be run without any component or cached processes may contain running components?

I think so no because minimum one activity is required for run the android programme.
