安卓编年史
蜂巢的应用列表少了很多应用。上图还展示了通知中心和新的快速设置。

默认的应用图标从32个减少到了25个，其中还有两个是第三方的游戏。因为蜂巢不是为手机设计的，而且谷歌希望默认应用都是为平板优化的，很多应用因此没有成为默认应用。被去掉的应用有亚马逊 MP3 商店，Car Home，Facebook，Google Goggles，信息，新闻与天气，电话，Twitter，谷歌语音，以及语音拨号。谷歌正在悄悄打造的音乐服务将于不久后面世，所以亚马逊 MP3 商店需要为它让路。Car Home，信息以及电话对一部不是手机的设备来说没有多大意义，Facebook 和 Twitter还没有平板版应用，Goggles，新闻与天气以及语音拨号几乎没什么人注意，就算移除了大多数人也不会想念它们的。
几乎每个应用图标都是全新设计的。就像是从 G1 切换到摩托罗拉 Droid，变化的最大动力是分辨率的提高。Nexus S 有一块800×480分辨率的显示屏，姜饼重新设计了图标等资源来适应它。Xoom 巨大的1280×800 10英寸显示屏意味着几乎所有设计都要重做。但是再说一次，这次是有真正的设计师在负责，所有东西看起来更有整体性了。蜂巢的应用列表从纵向滚动变为了横向分页式。这个变化对横屏设备有意义，而对手机来说，查找一个应用还是纵向滚动列表比较快。
第二张蜂巢截图展示的是新通知中心。姜饼中的灰色和黑色设计已经被抛弃了，现在是黑色面板带蓝色光晕。上面一块显示着日期时间，连接状态，电量和打开快速设置的按钮，下面是实际的通知。非持续性通知现在可以通过通知右侧的“X”来关闭。蜂巢是第一个支持通知内控制的版本。第一个（也是蜂巢发布时唯一一个）利用了此特性的应用是新的谷歌音乐，在它的通知上有上一曲，播放/暂停，下一曲按钮。这些控制可以在任何应用中访问到，这让控制音乐播放变成了一件轻而易举的事情。
“添加到主屏幕”的缩小视图更易于组织布局。搜索界面将自动搜索建议和通用搜索分为两个面板显示。

点击主屏幕右上角的加号或长按背景空白处就会打开新的主屏幕设置界面。蜂巢会在屏幕上半部分显示所有主屏的缩小视图，下半部分分页显示的是小部件和快捷方式。小部件或快捷方式可以从下半部分的抽屉中拖动到五个主屏幕中的任意一个上。姜饼只会显示一个文本列表，而蜂巢会显示小部件完整的略缩图预览。这让你更清楚一个小部件是什么样子的，而不是像原来的“日历”一样只是一个只有应用名称的描述。
摩托罗拉 Xoom 更大的屏幕让键盘的布局更加接近 PC 风格，退格，回车，shift 以及 tab 都在传统的位置上。键盘带有浅蓝色，并且键与键之间的空间更大了。谷歌还添加了一个专门的笑脸按钮。 :-)
打开菜单的 Gmail 在蜂巢和姜饼上的效果。按钮布置在首屏更容易被发现。

Gmail demonstrated all the new UI concepts in Honeycomb. Android 3.0 did away with hiding all the controls behind a menu button. There was now a strip of icons along the top of the screen called the Action Bar, which lifted many useful controls to the main screen where users could see them. Gmail showed buttons for search, compose, and refresh, and it put less useful controls like settings, help, and feedback in a dropdown called the "overflow" button. Tapping checkboxes or selecting text would cause the entire action bar to change to icons relating to those actions—for instance, selecting text would bring up cut, copy, and select all buttons.
The app icon displayed in the top left corner doubled as a navigation button called "Up." While "Back" worked similarly to a browser back button, navigating to previously visited screens, "Up" would navigate up the app hierarchy. For instance, if you were in the Android Market, pressed the "Email developer" button, and Gmail opened, "Back" would take you back to the Android Market, but "Up" would take you to the Gmail inbox. "Back" might close the current app, but "Up" never would. Apps could control the "Back" button, and they usually reprogrammed it to replicate the "Up" functionality. In practice, there was rarely a difference between the two buttons.
Honeycomb also introduced the "Fragments" API, which allowed developers to use a single app for tablets and phones. A "Fragment" was a single pane of a user interface. In the Gmail picture above, the left folder list was one fragment and the inbox was another fragment. Phones would show one fragment per screen, and tablets could show two side-by-side. The developer defined the look of individual fragments, and Android would decide how they should be displayed based on the current device.
The calculator finally used regular Android buttons, but someone spilled blue ink on the calendar.

For the first time in Android's history, the calculator got a makeover with non-custom buttons, so it actually looked like part of the OS. The bigger screen made room for more buttons, enough that all the calculator functionality could fit on one screen. The calendar greatly benefited from the extra space, gaining much more room for appointment text and controls. The action bar at the top of the screen held buttons to switch views, along with showing the current time span and common controls. Appointment blocks switched to a white background with the calendar corner only showing in the top right corner. At the bottom (or side, in horizontal view) were boxes showing the month calendar and a list of displayed calendars.
The scale of the calendar could be adjusted, too. By performing a pinch zoom gesture, portrait week and day views could show between five and 19 hours of appointments on a single screen. The background of the calendar was made up of an uneven blue splotch, which didn't look particularly great and was tossed on later versions.
The new camera interface, showing off the live "Negative" effect.

The giant 10-inch Xoom tablet did have a camera, which meant that it also had a camera app. The Tron redesign finally got rid of the old faux-leather look that Google came up with in Android 1.6. The controls were laid out in a circle around the shutter button, bringing to mind the circular controls and dials on a real camera. The Cooliris-derived speech bubble popups were changed to glowing, semi-transparent black boxes. The Honeycomb screenshot shows the new "color effect" functionality, which applied a filter to the viewfinder in real time. Unlike the Gingerbread camera app, this didn't support a portrait orientation—it was limited to landscape only. Taking a portrait picture with a 10-inch tablet doesn't make much sense, but then neither does taking a landscape one.
The clock app didn't get quite as much love as other areas. Google just threw it into a tiny box and called it a day.

Tons of functionality went out the door when it came time to remake the clock app. The entire "Deskclock" concept was kicked out the door, replaced with a simple large display of the time against a plain black background. The ability to launch other apps and view the weather was gone, as was the ability of the clock app to use your wallpaper. Google sometimes gave up when it came time to design a tablet-sized interface, like here, where it just threw the alarm interface into a tiny, centered dialog box.
The Music app finally got the ground-up redesign it has needed forever.
Ron Amadeo 供图
While music received a few minor additions during its life, this was really the first time since Android 0.9 that it received serious attention. The highlight of the redesign was a don't-call-it-coverflow scrolling 3D album art view, called "New and Recent." Instead of the tabs added in Android 2.1, navigation was handled by a Dropbox box in the Action Bar. While "New and Recent" had 3D scrolling album art, "Albums" used a flat grid of albums thumbnails. The other sections had totally different designs, too. "Songs" used a vertically scrolling list of text, and "Playlists," "Genres," and "Artists" used stacked album art.
In nearly every view, every single item had its own individual menu, usually little arrows in the bottom right corner of an item. For now, these would only show "Play" and "add to Playlist," but this version of Google Music was built for the future. Google was launching a Music service soon, and those individual menus would be needed for things like viewing other content from that artist in the Music Store and managing the cloud storage versus local storage options.
Just like the Cooliris Gallery in Android 2.1, Google Music would blow up one of your thumbnails and use it as a background. The bottom "Now Playing" bar now displayed the album art, playback controls, and a song progress bar.
Some of the new Google Maps was really nice, and some of it was from Android 1.5.

Google Maps received another redesign for the big screen. This one would stick around for a while and used a semi-transparent black action bar for all the controls. Search was again the primary function, given the first spot in the action bar, but this time it was an actual search bar you could type in, instead of a search bar-shaped button that launched a completely different interface. Google finally gave up on dedicating screen space to actual zoom buttons, relying on only gestures to control the map view. While the feature has since been ported to all old versions of Maps, Honeycomb was the first version to feature 3D building outlines on the map. Dragging two fingers down on the map would "tilt" the map view and show the sides of the buildings. You could freely rotate and the buildings would adjust, too.
Not every part of Maps was redesigned. Navigation was untouched from Gingerbread, and some core parts of the interface, like directions, were pulled straight from Android 1.6 and centered in a tiny box.
