Android - Save activity state when starting new activity?

I know I could use the Bundle savedInstanceState to manually save and restore the state by overriding onPause, onResume, on Create (etc), but there is actually lots of data in custom components that are not easily serializable, so I'd like to avoid that What you would "like" does not much matter. You need this code anyway to handle configuration changes (e.g. , switch from portrait to landscape). Please implement onSaveInstanceState() and onRestoreInstanceState() then back out all the rest of the inappropriate hacks that you have in your previous paragraph (e.

G singleInstance alwaysRetainTaskState ).

Well, obviously, what I "like" is dictated by the application imperatives. About those "inapropriate" hacks, maybe I'm missing the point, but why would they be inapropriate? Are they like things to avoid?

Seems pretty neat to me, but, once again, maybe I miss some information. And if I can get the behavior I want from them when I go back to home screen and to the application again, is it really bad to think that I could find the same kind of thing if I start the application from my activity? – Ours Feb 2 at 13:08 @Ours: "Are they like things to avoid?" -- the documentation explicitly states that singleInstance is "not appropriate for most applications", with the quoted passage highlighted in red.

AlwaysRetainTaskState="true" is fine for its intended purpose, but it is not supposed to be some sort of panacea for properly saving your instance state. – CommonsWare Feb 2 at 13:20 Ok. Doesn't mean it's not appropriate in my case.

And all of that doesn't solve my problem. Anyway, thanks for your answer and advices. – Ours Feb 2 at 13:29.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
