Hi guys thx for your help, been playing around with it and I tried setting
up a service which works, but this will run in the background all the time
so if I use an alarm manager how accurate is it can you set one for say 30
seconds time, or is it still bad to use a service even though all its doing
is waiting for handler.post() to come along to play a sound. The timer is
designed to have several times per timer so each timer will finish several
times, i.e pyramid splits, and can have many timers
