The main Activity I use in my Android application uses a fair amount of memory, meaning that on a less powerful phone, it is susceptible to being killed off when not at the front. Normally this is fine, but it also happens when I am still inside my application, but have a different activity at the top of the stack (such as a preference activity).

Obviously it's a problem if my application is killed while the user is still running it. Is there any way to disable the OS's ability to kill off the application for low memory problems?

Thanks.
