First, I'm not entirely sure what you're trying to achieve, but making
your code wake up every 15 seconds might cost your users a lot of
battery life for little result, when the user isn't actively using the
device. If you do some network activity every 15 seconds over a cell
network, you'll only have a few hours of battery life.
You really have two options here:
-if you really want to have a process stick around, you need to have a
Service in that process, so that the system can make the appropriate
decisions when it tries to make space for other applications. When the
process that hosts your service is killed, it'll eventually get
restarted automatically, so you can restart whatever you were doing in
the service's onCreate function. In that case, you'll find that using
a Handler is a much better idea than using Thread.sleep.
-if you can work without necessarily having a process stay up all the
time, you should look at the AlarmManager, which will allow the system
to free the memory associated with your process between ticks.
