Checking if an Android application is running in the background

Question

By background, I mean none of the application\'s activities are currently visible to the user?

Answer 1

There is no way, short of you tracking it yourself, to determine if any of your activities are visible or not. Perhaps you should consider asking a new StackOverflow question, explaining what it is you are trying to achieve from a user experience, so we can perhaps give you alternative implementation ideas.
