Google 在 Android Developer Blog 发表了一篇题为 “Say Goodbye to the Menu Button” 的文章。
文章主要是提醒开发人员，随着 Android 4.0 手机陆续推出，手机上不会再有 Menu 按键。App 内的 Menu 亦会逐渐淡出，取而代之的是 Action Bar。
In order to provide the most intuitive and consistent user experience in your apps, you should migrate your designs away from using the Menu button and toward using the action bar.
