Hi, I am trying to be notified when the current task has gone to the background/foreground. Note that I am not asking about the current activity, or the current application, or about any other different task.
The context for this question is that, in my case, some resources should be freed when the task goes to the background (and only then). This can be implemented with onStart/onStop in my application's activities, but this is not possible when external activities are being used. When we start an external activity with startActivityForResult (e.g. to pick a document or take a photo), Android places it on top of the current task's stack. However, there is apparently no way to get lifecycle callbacks from that new activity, even though it belongs to the same task as the rest of my application. In other words, I haven't found a way to detect if the current task has gone to the background when the activity on top of the stack is external to my application. Any ideas? Thank you for your help.
