How do I stop apps from getting killed while sleeping? I have a Droid 2.  I have a long, resource-intensive game (spectral souls) that I would like to leave running while I'm not using my phone.  If I hit the Android "Home" button to get back to the home screen and then immediately re-launch the game, it will be right where I left off.  Same if I hit the power button to sleep, and then immediately turn on the phone, unlock, and re-launch the game.

If I leave it for some amount of time (a few hours), then when I come back and launch the game, it starts fresh as if it were never running.  The phone hasn't been used for anything in the meantime, although syncing is on.

My question is twofold: how can I get more information about what apps are killed when &amp; why, and how can I set it up to allow this app to continue running?  I don't need it to DO anything in the background, I just want it to still be there when I come back.

I'm familiar with the concept of Android clearing memory as it's needed and not needing a task killer, but I want it to not kill THIS task unless I really exit it.
Suggestion: Use Tasker to disable screen timeout for your app. This may prevent it from going to the background.
