You are going to have to preserve your state either in that Bundle that you get in onCreate or somewhere on the file system. As several other people on this thread have pointed out, you can't control the lifecycle of your process and, by extension, your static finals.
Nor, btw, should you try. Work with Android, not against it. Think about your application state, not the state of the process that happens to power it, at the moment. Calling System.exit() is icky, to use a technical term.
