You can do it yourself.

The biggest design issue? No search and menu buttons. This opens up for all sorts of weird design and placement choices. Having back, home, menu and search as software/hardware buttons that are always there makes it so much easier. Having to search every app for these options take away space and is confusing. Buttons in apps, which could have been on the phone, is stupid and something I always found irritating about iOS. The way Google is heading with Android worries me to be honest. We don’t want to have an OS thats like iOS, thats why we chose Android in the first place. The Galaxy Nexus is a sweet phone, no doubt, but the new software buttons are just utterly useless. My greatest wish is for customizable software buttons through a rooted ROM, or even in stock, so that the screen can be used for actual content instead of trial and error button searching. When CM9 is finished and available for Galaxy Nexus I might consider buying it. For now I am holding on to my Desire (with 4 hardware buttons!) tightly.
I love Android so don’t hate me. But this is my honest opinion about the way the design is heading. It makes sense for Google to have this design page, it really does, but reducing four functional buttons to three was not a good choice. The recent apps is essentially useless, as you could always just hold down the home button. Sure its pretty and you can close apps, but who cares, it is not functional compared to search and menu. Especially menu. Having search and “options” buttons in an app is a waste of screen space.

This is just naive. I have a Galaxy Nexus and I have never had any difficulty locating the software buttons in any app. If you really have difficulty in finding the software buttons, it says more about you than about the software. They are standardised icons.

I can understand that someone might have a preference for hardware or software buttons, but to claim that this is “the biggest design issue” is just blowing it out of all proportion.

Great idea. I’m sure this will go a long way to helping devs who are design impaired

Actually, I tend to agree with him. it may not bea big deal, but a consistently located “more features” button is one of the features I would like to see kept. that said, ics solves the “is there something there” issue and continues to support an auto-hidden menu button. developers can still take advantage of it as far as i know.

This is why i like the G-Team…They listen to their customers, help their developers, and always finding ways to stay in the game…Go G-Team!!

There are lots of resources on the developer.android.com site already, including video tutorials etc. It’s a great place to start, try following their basic “Hello World” tutorial and see how that goes, it should give you a place to start.
