Google's doing a lot to bolster its Android developers guide at the moment, with fresh design tips we covered yesterday and then a new section on accessibility arriving shortly after. The latter provides a bunch of suggestions on things like minimum button size (48dp or around 9mm), and also explains how to make use of free components like TalkBack, which gives a spoken description of an app's UI, and Eyes-Free Keyboard, which many users find easier than regular touch-to-click. These stock services work best with apps that have been designed with them in mind, so if we were presumptuous enough to command all devs to look at the source link, then we probably would. (Do it. Do it.)
