{pagination} Android對USB的支持 Android將在新的平板電腦版Honeycomb 3.1和智能手機(jī)版Gingerbread 2.3.4中首次支持USB。該支持包括一種新的Open Accessory API，含有谷歌提供的一個USB支持庫。 Android與眾不同，因其被定義為一個設(shè)備，不是Linux下面的一個主機(jī)環(huán)境。因此，Android USB附件從技術(shù)角度來看將是USB主機(jī)。谷歌庫旨在為開發(fā)者消除這種差別。 這種設(shè)備/主機(jī)情形意味著Android USB附件將不能通過USB從Android手機(jī)或平板電腦獲得電源。谷歌目前沒有開發(fā)對USB 3.0的支持。 谷歌、Microchip和日本RT Corp.宣布了用于建立Android USB附件的硬件開發(fā)者工具。在一個視頻中，Microchip的一名工程師演示了該公司的工具套件，使用基于MIPS的處理器。 谷歌表示，將來也會推出對使用藍(lán)牙的Android附件的支持。谷歌的一名經(jīng)理把新興的Android附件市場與iPhone和iPad附件市場進(jìn)行了對比。蘋果嚴(yán)密控制其附件市場。 “生產(chǎn)附件將沒有NDA和費(fèi)用，也不需要批準(zhǔn)，因此放手做吧，”谷歌Android的產(chǎn)品管理總監(jiān)Hugo Barra表示。 另外，谷歌宣布了Android @ Home，用于通過Wi-Fi或某種無線家庭控制網(wǎng)絡(luò)，把Android設(shè)備連接到多種家用電器和家庭自動化設(shè)備。LED燈與開關(guān)生產(chǎn)商Lighting Science表示，將在年底推出一款LED燈泡，可以由Android設(shè)備進(jìn)行無線控制。 @ Home項目包括一個用于控制家庭媒體系統(tǒng)的硬件參考設(shè)計——Project Tungsten。谷歌展示了一個與網(wǎng)絡(luò)相連的Tungsten裝置，控制一個立體聲系統(tǒng)，通過晃動具有近距通訊鏈接的設(shè)備，就能夠購買或啟動互聯(lián)網(wǎng)音頻流。 “它組合了新型云服務(wù)、軟件和設(shè)備，開啟了一個完整的應(yīng)用領(lǐng)域，”作演示的一個谷歌開發(fā)者表示。 Android @ Home軟件與無線網(wǎng)絡(luò)支持細(xì)節(jié)將在今年稍晚的時候公布。 本文授權(quán)編譯自EE Times，版權(quán)所有，謝絕轉(zhuǎn)載 查看英文原文Android gets more unity USB support

{pagination} Android gets more unity USB support SAN FRANCISCO, Calif. – At its annual developers conference, Google outlined its plans to pull together separate versions of its Android environment and extend the software to support USB. Support for tablet, smartphone and television versions of Android will come together in a so-called Ice Cream Sandwich version of the software to be released as open source code in the fourth quarter. The current Honeycomb version 3.0 for tablets and a 3.1 upgrade due within weeks will not be made available as open source. GoogleTV client software will continue to be a separate variant of Android, but starting this summer apps developed for it will become available in the public Android apps market online. "We want one OS that runs everywhere, and we want to insulate developers from differences in devices," said Mike Cherod, a Google developer working on Ice Cream Sandwich, alluding to additional tools to be announced tomorrow at the Google I/O event here. Google has released eight versions of Android in two and a half years. It is currently being used on 310 different devices and was activated on 100 million phones in 2011 with activations tracking at 400,000 a day, said Hugo Barra, director of Android product management in a Google I/O keynote. Google angered OEMs by refusing to release as open source its Honeycomb software for tablets. In addition, earlier this year, it re-tooled plans for GoogleTV software announced at this event a year ago. Separately, Google announced an alliance of more than a dozen partners that will define a standard plan for upgrading devices in the field to bring greater unity to the Android market. The group includes AT&T, HTC, LG, Motorola, Samsung, Sony Ericsson, Verizon and Vodaphone. They have initially pledged to make any Android upgrades available on devices in the field for the first 18 months after their purchase. In addition, Google announced new streaming video and music services for Android devices, based on Google cloud services. USB support for Android Google will support USB for the first time on the next version of its software for tablets, Honeycomb 3.1, and the smartphone version, Gingerbread 2.3.4. The support includes a new Open Accessory API which includes USB support libraries from Google. Android is unusual in that it is defined as a device, not a host environment under Linux. Thus Android USB accessories will technically be USB hosts. The Google libraries aim to smooth over that distinction for developers. The device/host situation means Android USB accessories will not be able to get power over USB from Android handsets or tablets. Google is not developing support for USB 3.0. Google, Microchip and RT Corp. of Japan announced hardware developers kits for building Android USB accessories. In a video, a Microchip engineer demonstrated his company's kit which uses a MIPS-based processor. Google said it will also release support for Android accessories using Bluetooth in the future. A Google manager contrasted the new Android peripheral market to the tightly controlled one maintained by Apple for its iPhone and iPad. "There will be no NDAs or fees and no approval process to build accessories, so go get started," said Hugo Barra, director of product management for Android at Google. Separately Google announced Android @ Home, an initiative to link Android devices to a broad range of home appliances and home automation devices over Wi-Fi or an unspecified wireless home control network. Lighting Science, an LED light and switch maker, said it will release LED light bulbs and switches by end of year that can be controlled wirelessly by Android devices. The @ Home initiative includes a hardware reference design for controlling home media systems, called Project Tungsten. Google demoed a Tungsten box linked to the Web, controlling a stereo and capable of buying or starting an Internet audio stream based on waving a device with a near field communications link. "This combination of new cloud services, software and devices enables a whole universe of applications," said a Google developer giving the demo. The Android @ Home software and details of its wireless network support will be released late this year.
