Lets say you are in "maps", layers, more layers, favorite places,London screen.
Now take me back to maps without selecting anything. (I'm in NY) and without clicking 5 times back, or going thru home and clicking maps again.
It's not difficult press back 5 times... no.
Actually, I just counted 4 clicks for that and I followed your steps. (I'm using the latest version of maps but - 1. layers, 2. more layers, 3. favorite places, 4. London screen - that's 4 in, so it's 4 out.)
I also tried Alexie Sayle (HI ALEXIE!) to get out the sub-menus, saw a little of London and then just hit my location button, upper left, to get back to me.
OK - you're again getting creamed because we all thought you were referring to something else entirely.
You're referring to the hierarchical pop-up sub-menu navigation within an app, not app page navigation.
Not to be flippant - but I don't think it's a highly common use to get from home to London and then decide that the last you wanted was to visit a foreign city at all. Had you made the last step into London, you'd have been only one button from returning home.
This sort of thing isn't just common to Android - managing hierachical sub-menus on embedded systems with touchscreens - not uncommon for the behavior you're seeing at all.
You might suggest to Google (not being sarcastic) that the standard service that apps link to for pop-ups like that include an upper-right X button.
I suspect that they'll evaluate the suggestion in terms of use cases and need.
PS - Web designs don't seem to have that sort of elements per se. I guess you're expecting that that's like a web popup where you control things in the main navigation and then can kill the pop-up. And Windows sub-menus rarely go as deep as three levels - if that - and you have a mouse to get out of the sub-hierarchy quickly. And a bigger screen to manage it all in.
PPS - When I asked for the example 10 minutes after you posted it, please understand I do read all of your posts - I'd simply asked that being seeing your earlier post. As a mod, I have the pleasure of trying to post and do site maintenance at the same time, and I can't always finish a post quickly enough.
