Does anybody have any suggestions/recommendations for cancelling and saving within android? The issue that I'm having is I have to open a screen in a full screen dialog with save-able options on it, but there is also an option to move to another screen within the dialog with yet more save-able option. I don't know what to do when the user goes to the second screen. Should there be more save and cancel options on that, should changes just be saved automatically? I've looked through other android apps but I haven't found anything similar.
I'd love to be able to keep all data on a single screen but I haven't found a solution for it. It's for a checkout flow, when a user wants to change their address.
