Detailed Description

Counts the started browser activities of the process and arms an idle timer only when the count drops to zero.

Why a counter and not "arm in onStop, cancel in onResume": when the layout changes, the old browser's onStop runs after the new browser's onResume, so a timer armed there would never be cancelled. Rotation has the same shape. Plain Java (no Android imports) so it can be unit tested; the Android side supplies the Scheduler. Call from the main thread only; all methods are synchronized anyway so a stray caller cannot corrupt the count.
