Hi, I'm developing an application which consists of two different activities which edit files. The two activities run in separate processes. Multiple instances of both activities can be launched concurrently in different tasks. Each activity instance is passed a file path to work on in its intent. I'd like to make it so that a given file cannot be edited in more than one activity instance at the same time.
As far as my understanding goes, I have to use a Service. Each activity instance must ask the service whether it is allowed to acquire the "editing rights" for the file passed in its intent. The service will keep a set of open files. Set entries will be removed when activity instances are closed. The problem is that the service process can be killed at almost any time. There is not any method like Activity.saveInstanceState(...) in Service. How is the set of open files supposed to persist an eventual killing and later re-launching of the service process? -- You received this message because you are subscribed to the Google Groups "Android Developers" group.
