android intel Atom news

shared by Vincent Tsao on 09 May 10 - Cached
  • 我们都知道Intel一直在试图将Android带到自己的Atom平台上，1个月前他们宣布了Atom已经可以成功运行Android和Meego系统，今天他们又透露了这颗Atom芯片的一些技术细节。 这颗Atom芯片属于Z6xx系列，在手机上可达到1.5GHz的主频，在平板上更是可以摸高到1.9GHz的速度，足以提供1080p视频的解码和720p视频的录制，帮助3D显卡闲置功耗降低50倍以上，等于多赋予电池10天的待机。这个新的芯片组应该可以提供长达2天的音频回放和4-5小时的视频浏览。 对Android的支持方面，Z6xx平台可支持标准的WiFi、3G/HSPA和WiMAX无线连接。之前传说Google和索尼联手打造的Android TV就内置了Intel的Atom芯片，那么很可能就是Z6xx系列，我们会在5月19日的Google I/O大会上见到运行Android的Atom芯片的庐山真面目。

  • onSaveInstanceState() is called by Android if the Activity is being stopped and may be killed before it is resumed! This means it should store any state necessary to re-initialize to the same condition when the Activity is restarted. It is the counterpart to the onCreate() method, and in fact the savedInstanceState Bundle passed in to onCreate() is the same Bundle that you construct as outState in the onSaveInstanceState() method.
  • Note that saveState() must be called in both onSaveInstanceState() and onPause() to ensure that the data is saved. This is because there is no guarantee that onSaveInstanceState() will be called and because when it is called, it is called before onPause().

  • The density of a screen is important because, other things being equal, a UI element (such as a button) whose height and width are defined in terms of screen pixels will appear larger on the lower density screen and smaller on the higher density screen.
  • The density-independent pixel is equivalent to one physical pixel on a 160 dpi screen, the baseline density assumed by the platform (as described later in this document). At run time, the platform transparently handles any scaling of the dip units needed, based on the actual density of the screen in use. The conversion of dip units to screen pixels is simple: pixels = dips * (density / 160). For example, on 240 dpi screen, 1 dip would equal 1.5 physical pixels. Using dip units to define your application's UI is highly recommended, as a way of ensuring proper display of your UI on different screens.

  • 根据NPD的报告，Android操作系统手机在美国智能手机市场份额达到28%，领先于苹果21%，排在首位的是RIM，份额为36%。 对此，苹果称NPD的数据不完整。公司新闻发言人娜塔莉·哈里森（Natalie Harrison）说：“15万美国用户向在线咨询提交数据，这十分有限，它没有包括全球8500万的iPhone、iPod Touch用户。”娜塔莉·哈里森进一步说，从全球范围来看iPhone销量远胜Android手机，IDC上周发布的数据显示，iPhone拥有全球智能手机市场份额达16.1%，居诺基亚和RIM之后。 娜塔莉·哈里森称：“我们iPhone的销量上个季度创了历史，增长131%，新的iPhone OS 4.0也将于夏季推出，我们一点也没看到竞争对手赶上的迹象。” 从2007年iPhone上市以来，共售出5100万台。

  • 面向杂志、报纸数字化发布的德国软件公司 Neofonie GmbH 近日发布了自己的平板电脑——WePad 以配合自家的内容发布平台 WeMagazine。
  • Neofonie 表示产品预期在今年 4 月发售，有可能早于 iPad 在欧洲的发售日期。WePad 的规格表看起来确实很美，增加了很多 iPad 缺失的重要功能，但至关重要的软件系统最终表现如何还无从得知。对于一家基本没有操作系统开发经验的小公司而言，这是一个相当有挑战性的任务。
  • ...2 more annotations...
  • WePad 有很多亮点，比如它采用了自己修改的 Linux 平台搭配 Android 系统，允许用户同时安装使用 Android Market 和 Adobe Air 程序；它采用了类似 iPad 的玻璃外屏和金属机身；其它配置也明显瞄准着 iPad
  • 不过这家小公司的野心还远不止于此，他们在介绍 WeMagazine 平台时也直言不讳自己以 iBooks 和 Kindle 商店为目标，写道： Apple iTunes 和 Amazon Kindle 强迫出版商退化为简单的内容提供商，而 WePad 允许出版商继续接触读者的信息。

Android Rises in Mobile Web Usage, iPhone Stagnates, Declines - 0 views

  • Worldwide, it doesn't look so bad for Apple yet; it's still the king of the hill by a long shot, steady at about 50%. Android is making inroads, though, now accounting for almost a quarter of the world's mobile web usage.
  • And now we get to the interesting part: the United States. The top-notch Android phones have been available in the US for longer than in other countries, and carriers there have been pushing them longer. This shows: in the US, Android has almost overtaken the iPhone OS (which excludes the iPod Touch!) in mobile web usage - 42% vs. 44%.
  • ...2 more annotations...
  • In November 2009, the iPhone OS accounted for 55% of the mobile web usage in the US; now it's down to 44%. In the same timespan, Android grew from 27% to 42%. The US can be seen as a test bed for the rest of the world, since Android hasn't been pushed as much outside of the US as it has been inside of the US. In Apple's defence, though, the arrival of the iPad in the coming weeks may reverse the declining trend of the iPhone OS. And, as noted, the iPod Touch is not included in these figures. All in all, it's clear that Android is no longer just a speck on the horizon. Google's mobile operating system is a serious threat to Apple's iPhone, which could further explain why Apple decided to sue HTC. Jobs might be drinking coffee with Schmidt in a nicely staged press moment, but in the meantime, the '80s and '90s are happening all over again for Apple: the PC business model beating the Mac one.

  • Some of the highlights from the report include: Smartphones accounted for 48% of AdMob’s worldwide traffic, up from 35% in February 2009, fueled by heavy application usage on iPhone and Android devices. Although the share of feature phone traffic in AdMob’s network declined from 58% to 35%, the absolute traffic from feature phones still grew 31%.  This means that while the overall traffic from feature phones is growing, traffic from smartphones and mobile Internet devices is growing faster. The mobile Internet device category experienced the strongest growth of the three, increasing to account for 17% of traffic in AdMob’s network in February 2010.  Although the vast majority of traffic in this category comes from the iPod touch, the category also includes devices like the Sony PSP and Nintendo DSi.

It’s also great for collaboration — we’ve been using it around the TechCrunch office to share files for years now
