Please don't do that. First, it's not possible: http://www.androidguys.com/2009/09/09/diamonds-are-forever-services-are-not/ Second, it's a bad idea to even try: http://www.androidguys.com/2010/03/29/code-pollution-background-control/ > Now, the problem is it can't only have one of this service running. What is "it"? Services are natural singletons -- there is exactly 0 or 1 copy of the service running at any point. The goal is for there to be 0 copies of the service running unless it is actively delivering user-perceived value. -- Mark Murphy (a Commons Guy) http://commonsware.com | http://twitter.com/commonsguy _Beginning Android 2_ from Apress Now Available! -- You received this message because you are subscribed to the Google Groups "Android Developers" group.
