Lots of Android countdown timers out there, but not what I want.
The one below comes close:https://play.google....mbo.ovo&hl=en_US
Here is what it lacks, that I'd really like to have:
-- Save user-defined/adjustable default countdown amount. (20 minutes)
-- Start counting down as soon as program runs, no user intervention needed.
-- Make sure program can be scheduled to run on device (tablet) start.
-- Allow for playing whatever 'sounds' are available in system. (series of beeps)
-- If possible, pause the existing music being played (AIMP), and after sounding (beeping for 3 to 5 seconds), allow music to resume.
-- When alarm goes off, don't require any user intervention. Just close and disappear.
No need for any other bells and whistles.
