  • 0

I am working on an Android application where I would want to switch between 3 activities (say Home, Map and Photo). Right now the flow is like ‘Home>Map>Photo’. I would like to allow the user to switch between these 3 activities. Say if he wants to go from Photo to Map or from Photo to Home without destroying the Photo activity. What is the best way in Android to achieve this?

I went through other answers on SO but it seems like caching the data somewhere is the only feasible way which does not break other functionality (For ex. back button).

— Edit —

I want this to work exactly like the way TabHost works. Will appreciate any ideas about how to achieve that.

    Ok, so this is what I ended up doing to restore the state once the activity finishes.

    • Store all primitive variables in the SharedPreferences of the activity.
    • Store images as files.
    • Will use SQLite if needed.

    I also looked at db4o android but not sure whether I’ll use it.
