### Android 1.0—introducing Google Apps and actual hardware ###
|
||||
|
||||
By October 2008, Android 1.0 was ready for launch, and the OS debuted on the [T-Mobile G1][1] (AKA the HTC Dream). The G1 was released into a market dominated by the iPhone 3G and the [Nokia 1680 classic][2]. (Both of those phones went on to tie for the [best selling phone][3] of 2008, selling 35 million units each.) Hard numbers of G1 sales are tough to come by, but T-Mobile announced the device broke the one million units sold barrier in April 2009. It was way behind the competition by any measure.
|
||||
|
||||
The G1 was packing a single-core 528Mhz ARM 11 processor, an Adreno 130 GPU, 192MB of RAM, and a whopping 256MB of storage for the OS and Apps. It had a 3.2-inch, 320x480 display, which was mounted to a sliding mechanism that revealed a full hardware keyboard. So while Android software has certainly come a long way, the hardware has, too. Today, we can get much better specs than this in a watch form factor: the latest [Samsung smart watch][4] has 512MB of RAM and a 1GHz dual-core processor.
|
||||
|
||||
While the iPhone had a minimal amount of buttons, the G1 was the complete opposite, sporting almost every hardware control that was ever invented. It had call and end call buttons, home, back, and menu buttons, a shutter button for the camera, a volume rocker, a trackball, and, of course, about 50 keyboard buttons. Future Android devices would slowly back away from thousand-button interfaces, with nearly every new flagship lessening the number of buttons.
|
||||
|
||||
But for the first time, people saw Android running on actual hardware instead of a frustratingly slow emulator. Android 1.0 didn't have the smoothness, flare, or press coverage of the iPhone. It wasn't as capable as Windows Mobile 6.5. Still, it was a good start.

The core of Android 1.0 didn't look significantly different from the beta version released two months earlier, but the consumer product brought a ton more apps, including the full suite of Google apps. Calendar, Email, Gmail, IM, Market, Settings, Voice Dialer, and YouTube were all new. At the time, music was the dominant media type on smartphones, the king of which was the iTunes music store. Google didn't have an in-house music service of its own, so it tapped Amazon and bundled the Amazon MP3 store.
|
||||
|
||||
The most important addition to Android 1.0 was the debut of Google's store, called "Android Market Beta." While most companies were content with calling their app catalog some variant of "app store"—meaning a store that sold apps and only apps—Google had much wider ambitions. It went with the much more general name of "Android Market." The idea was that the Android Market would not just house apps, but everything you needed for your Android device.
|
||||
|
||||
|
||||

||||
|
||||
At the time, the Android Market only offered apps and games, and developers weren't even able to charge for them. Apple's App Store had a four-month head start on the Android Market, but Google's big differentiator was that Android's store was almost completely open. On the iPhone, apps were subject to review by Apple and had to meet design and technical guidelines. Potential apps also weren't allowed to duplicate the stock functionality. On the Android Market, developers were free to do whatever they wanted, including replacing the stock apps. The lack of control would turn out to be a blessing and a curse. It allowed developers to innovate on the existing functionality, but it also meant even the trashiest applications were allowed in.
|
||||
|
||||
Today, this client is another app that can no longer communicate with Google's servers. Luckily, it's one of the few early Android apps [actually documented][6] on the Internet. The main screen provided links to the common areas like Apps, Games, Search, and Downloads, and the top section had horizontally scrolling icons for featured apps. Search results and the "My Downloads" page displayed apps in a scrolling list, showing the name, developers, cost (at this point, always free), and rating. Individual app pages showed a brief description, install count, comments and ratings from users, and the all-important install button. This early Android Market didn’t support pictures, and the only field for developers was a description box with a 500-character limit. This made things like maintaining a changelog very difficult, as the only spot to put it was in the description.
|
||||
|
||||
Right out of the gate, the Android Market showed permissions that an app required before installing. This is something Apple wouldn't get around to implementing until 2012, after an iOS app was caught [uploading entire address books][7] to the cloud without the user's knowledge. The permissions display gave a full rundown of what permissions an app was using, although this version railroaded users into agreeing. There was an “OK" button, but no way to cancel other than the back button.

The next most important app was probably Gmail. Most of the base functionality was here already. Unviewed messages showed up in bold, and labels displayed as colored tags. Individual messages in the Inbox showed the subject, author(s), and number of replies in a conversation. The trademark Gmail star was here—a quick tap would star or unstar something. As usual for early versions of Android, the Menu housed all the buttons on the main inbox view. Once inside a message, though, things got a little more modern, with "reply" and "forward" buttons as permanent fixtures at the bottom of the screen. Individual replies could be expanded and collapsed just by tapping on them.
|
||||
|
||||
The rounded corners, shadows, and bubbly icons gave the whole app a "cartoonish" look, but it was a good start. Android's function-first philosophy was really coming through here: Gmail supported labels, threaded messaging, searching, and push e-mail.

But if you thought Gmail was ugly, the Email app took it to another level. There was no separate inbox or folder view—everything was mashed into a single screen. The app presented you with a list of folders and tapping on one would expand the contents in-line. Unread messages were denoted with a green line on the left, and that was about it for the e-mail interface. The app supported IMAP and POP3 but not Exchange.

The history of Android

### 安卓1.0——谷歌系app和实体硬件的引入 ###
|
||||
|
||||
到了2008年10月，安卓1.0已经准备好发布，这个系统在[T-Mobile G1][1]（又以HTC Dream为人周知）上初次登台。G1进入了被iPhone 3G和[Nokia 1680 classic][2]所主宰的市场。（这些手机并列获得了2008年[销量最佳手机][3]称号，各自卖出了350万台。）G1的销量数字已难以获得，但T-Mobile宣称截至2009年4月该设备的销量突破了100万台。无论从哪方面来说这在竞争中都处于落后地位。
|
||||
|
||||
G1拥有单核528Mhz的ARM 11处理器，一个Adreno 130的GPU，192MB内存，以及多达256MB的存储空间供给系统以及应用使用。它有一块3.2英寸，320x480分辨率的显示屏，被布置在一个含有实体全键盘的滑动结构之上。所以尽管安卓软件的确走过了很长的一段路，硬件也是的。时至今日，我们可以在厂商的一个手表中得到比这更好的参数：最新的[三星智能手表][4]拥有512MB内存以及1GHz的双核处理器。
|
||||
|
||||
当iPhone有着最少数量的按键的时候，G1确实完全相反的，按键几乎支持每个硬件控制。它有拨通和挂断按钮，home键，后退，以及菜单键，一个相机快门键，音量控制键，一个轨迹球，当然，还有50个键盘按钮。未来安卓设备将会慢慢离开按键多多的界面设计，几乎每部新旗舰都在减少按键的数量。
|
||||
|
||||
但是这是第一次，人们见到了运行在实机上的安卓，而不是跑在一个令人沮丧的慢吞吞的模拟器上。安卓1.0没有iPhone那样顺滑流畅，闪亮耀眼，或拥有那么多的新闻报道。它也不像Windows Mobile 6.5那样才华横溢。但这仍然是个好的开始。
|
||||
|
||||
|
||||
安卓1.0和0.9的默认应用列表。

|
||||
|
||||
安卓1.0的核心与两个月前发布的beta版本相比看起来并没有什么引人注目的不同，但消费者产品带来了不少应用，包括一套完整的谷歌系应用。日历，电子邮件，Gmail，即时通讯，市场，设置，语音拨号，以及YouTube都是全新登场。那时候，音乐是智能手机上占据主宰地位的媒体类型，其王者是iTunes音乐商店。谷歌没有自家的音乐服务，所以它选择了亚马逊并绑定了亚马逊MP3商店。
|
||||
|
||||
安卓最重要的新增是谷歌商店的首次登场，叫做“安卓市场Beta”。与此同时大部分公司满足于将它们的软件目录称作一些不同的“应用商店”——意思是一个出售应用的商店，并且只出售应用——谷歌明显有着更大的野心。它搭配了一个更为通用的名字，“安卓市场”。这个名字的想法是安卓市场不仅仅拥有应用，还拥有一切你的安卓设备所需要的东西。
|
||||
|
||||
|
||||

||||

|
||||
|
||||
那时候，安卓市场只提供应用和游戏，开发者们甚至还不能为它们收费。苹果的App Store相对与安卓市场有4个月的先发优势，但是谷歌的主要差异化在于安卓的商店几乎是完全开放的。在iPhone上，应用受制于苹果的审查，必须遵循设计和技术指南。潜在的新应用不允许在功能上复制已有应用。在安卓市场，开发者可以自由地做任何想做的，包括开发替代已有的应用。控制的缺失会转变成祝福同时也是诅咒。它允许开发者革新已有的功能，但同时意味着甚至是毫无价值的垃圾应用也被允许进入市场。
|
||||
|
||||
现在，这个客户端是又一个不再能够和谷歌服务器通讯的应用。幸运的是，它也是在因特网上被[真正记录][6]的为数不多的早期安卓应用之一。主页提供了通向一般区域的连接，像应用，游戏，搜索，以及下载，顶部有横向滚动显示的特色应用图标。搜索结果和“我的下载”页面以滚动列表的方式显示应用，显示应用名，开发者，费用（在那时都是免费的），以及评分。单独的应用页面展示了一个简短的描述，安装数，用户评论和评分，以及最重要的安装按钮。早期的安卓市场不支持图片，开发者唯一能使用的区域是应用描述，还有着500字的限制。这使得类似维护一个更新日志变的十分困难，因为只有描述的位置可以供其使用。
|
||||
|
||||
就在安装之前，安卓市场显示了应用所需要的权限。这是苹果直至2012年之前都避免做的，那年一个iOS应用被发现在用户不知情的情况下[将完整的通讯录上传][7]到云端。权限显示给出了一个完整的应用用到的权限列表，尽管这个版本强迫用户同意应用权限。界面有个“OK”按钮，但是除了后退按钮没有办法取消。
|
||||
|
||||
|
||||
Gmail展示收件箱，打开菜单的收件箱。
|
||||

|
||||
|
||||
下一个重要的应用也许就是Gmail。大多数基本的功能此时已经准备好了。未读邮件以加粗显示，标签是个有颜色的标记。在收件箱中每封独立邮件显示着主题，发件人，以及一个会话中的回复数。Gmail加星标志也在这里——快速点击即可给邮件加星或取消。一如往常，对于早期版本的安卓，菜单里有收件箱视图应有的所有按钮。但是，一旦打开了一封邮件，界面看起来就更加的现代了，“回复”和“转发”按钮永久固定在了屏幕底部。各个独立回复可以点击它们来展开和收缩。
|
||||
|
||||
圆角，阴影，以及气泡图标给了整个应用“卡通”的外表，但是这是个好的开始。安卓的功能第一哲学真正从此开始：Gmail支持标签，邮件会话，搜索，以及邮件推送。
|
||||
|
||||
|
||||
Gmail在安卓1.0的标签视图，写邮件界面，以及设置。
|
||||
Ron Amadeo供图
|
||||
|
||||
但是如果你认为Gmail很丑，电子邮件应用又拉低了下限。它没有分离的收件箱或文件夹视图——所有东西都糊在一个界面。应用呈现给你一个文件夹列表，点击一个文件夹会以内嵌的方式展开内容。未读邮件左侧有条绿色的线指示，这就是电子邮件应用的界面。这个应用支持IMAP和POP3，但是没有Exchange。
