Generally, yes. > 2) When does an Application's JVM exit - assuming there is one JVM per > application. That is unclear and definitely varies. For example, the process may be terminated quickly enough that the JVM does not go through a normal shutdown procedure. In other words, I would not rely upon deleteOnExit. > 3) Can a JVM exit when the application is running but being suspended > by the OS? Yes, because there isn't really a "running but being suspended" notion, at least as I think of the terms. It is much simpler to not think of you having an "application", so much as you having a basket of components (activities, services, etc.). Those components may come and go, and Android handles all the issues surrounding processes and JVMs behind the scenes. Part of the way Android handles that, though, may result in behavior very different than your traditional desktop JavaSE application. Hence, again, I wouldn't rely upon deleteOnExit. -- Mark Murphy (a Commons Guy) http://commonsware.com | http://twitter.com/commonsguy Android Training in US: 14-18 June 2010: http://bignerdranch.com -- You received this message because you are subscribed to the Google Groups "Android Developers" group.
