LATEST ANDROID SPECIFICATION

The Android logo was designed with the Droid font family made by Ascender Corporation.[94]
Android Green is the color of the Android Robot that represents the Android operating system. The print color is PMS 376C and the RGB color value in hexadecimal is #A4C639, as specified by the Android Brand Guidelines.[95] The custom typeface of Android is called Norad. It is only used in the text logo.[96]
[edit] Market share Research company Canalys estimated in Q2 2009 that Android had a 2.8% share of worldwide smartphone shipments.[97] By Q4 2010 this had grown to 33% of the market, becoming the top-selling smartphone platform. This estimate includes the Tapas and OMS variants of Android.[13]
 
In February 2010 ComScore said the Android platform had 9.0% of the U.S. smartphone market, as measured by current mobile subscribers. This figure was up from an earlier estimate of 5.2% in November 2009.[98] By the end of Q3 2010 Android's U.S. market share had grown to 21.4 percent.[99]
In May 2010, Android's first quarter U.S. sales surpassed that of the rival iPhone platform. According to a report by the NPD group, Android achieved 25% smartphone sales in the US market, up 8% from the December quarter. In the second quarter, Apple's iOS was up by 11%, indicating that Android is taking market share mainly from RIM, and still has to compete with heavy consumer demand for new competitor offerings.[100] Furthermore, analysts pointed to advantages that Android has as a multi-channel, multi-carrier OS, which allowed it to duplicate the quick success of Microsoft's Windows Mobile.[101]
In early October 2010, Google added 20 countries to its list of approved submitters. By mid-October, purchasing apps will be available in a total of 32 countries.[102] For a complete list of countries that are allowed to sell apps and those able to buy them see Android Market.



 
As of December 2010 Google said over 300,000 Android phones were being activated daily,[103] up from 100,000 per day in May 2010.In February 2011, during the 2011 Mobile World Congress, Eric Schmidt announced that Android has reached 350,000 activations per day.At Google I/O, May 10, 2011, Google announced that 400,000 new Android devices are activated every day and more than 100 million have been activated.Android's kernel is derived from the Linux kernel but has included architecture changes by Google outside the typical Linux kernel development cycle.[107] Android does not have a native X Window System nor does it support the full set of standard GNU libraries, and this makes it difficult to port existing GNU/Linux applications or libraries to Android.[108] However, support for the X Window System is possible.[109] Google no longer maintains the code they previously contributed to the Linux kernel as part of their Android effort, creating a separate version or fork of it.[110][111] This was due to a disagreement about new features Google felt were necessary (some related to security of mobile applications).[112] The code which is no longer maintained was deleted in January 2010 from the Linux kernel codebase.[113]Google announced in April 2010 that they will hire two employees to work with the Linux kernel community.[114]However, as of May 2011, points of contention still exist between Google and the Linux kernel team: Google tried to push upstream some Android-specific power management code in 2009, which is still rejected today.[115].Furthermore, Greg Kroah-Hartman, the current Linux kernel maintainer for the -stable branch, said in December 2010 that he was concerned that Google was no longer trying to get their code changes included in mainstream Linux.[116] Some Google Android developers hinted that "the Android team was getting fed up with the process," because they were a small team and had more urgent work to do on Android.
