That was not a joke.
Read the design guide -- it promotes the idea of having one "master button" -- for the screen's "primary action".
This means -- other actions will not be accessible as buttons, and will take more taps to get to.
For example, the "select all" button, refresh, or search (in a folder).
Taking "select all" as an example. I get questions on how select "all" messages at once, so more taps is a big deal to those users -- and adding even more, does it seem like a joke?
Material design guide is also "preliminary" and has inconsistencies. Let's talk about selection again:
http://www.google.com/design/spec/patterns/selection.html"long-press and two-finger touch may be extended by a drag gesture to select multiple items when initiating selection"
Long press and drag is already used in Android for drag and drop, since 3.0.
And about those buttons again -- "icons along the bottom in portrait mode" first appeared in Android 4.0, and it still works in 4.4.
In Android L preview, it doesn't work when using the "material theme". I did report this as a bug a few months ago, it's still not fixed in the preview build from a few days ago.
Does this mean that "icons along the bottom" are gone? So I'll be *forced* to use "one big button per screen" (and at most two buttons along the top) layouts? Existing users won't be happy. Still funny?
Sure, I can join the choir, just watch me --
"With Android L, Google makes a bold departure from old and rusty design metaphors, and breaks through into the world of brand new, intuitive, appealing design that combines intuitive usability with pleasing aesthetics"
-- but when you start working through the details, it just doesn't seem so shiny anymore.
-------
On the other hand -- I don't understand what *specifically* users expect from "Android L and material design", other than "oh, it's Android L and material design"? Anything?
I did understand how with Android 3.0, it became possible to write apps with side by side layouts. I've done that. Then swiping became fashionable, ok, here it is (navigation drawer, message actions).
But the notion that computer interfaces are supposed to mimic layers of paper, with ink "under" and "above", and sliding pieces everywhere...
Huh?
Maybe I'm just too dumb.
