Android History

                    Android release in 2007, the Open Handset Alliance announced the Android platform and launched a beta program for developers. Android went through the typical revisions of a new
platform. Several prerelease revisions of the Android Software Development Kit (SDK) were released. The first Android handset (the T-Mobile G1) began shipping in late 2008. Throughout 2009 and 2010, new and exciting Android smartphones reached markets throughout the world and the platform proved itself to industry and consumers alike. Over the last three years, numerous revisions to the Android platform have been rolled out, each providing compelling features for developers to leverage and users to enjoy. Recently, mobile platforms have begun to consider devices above and beyond the traditional smartphone paradigm, to other devices like tablets, e-book readers, and set-top boxes like Google TV.

                    As of this writing, hundreds of varieties of Android devices are available to consumers
around the world from high end smartphones to low end “free with contract” handsets and everything in between. This figure does not include the numerous Android tablet and e-book readers also available, the dozens of upcoming devices already announced, or the consumer electronics running Android.There are more than 200,000 applications currently published on the Android Market. In the United States, all major carriers now carry Android phones prominently in their product lines, as do many in Asia, Europe, Central/South America, and beyond. The rate of new Android devices reaching the world markets has continued to increase.

                    Google has been a contributing member of the Open Handset Alliance from the
beginning. The company hosts the Android open source project as well as the developer website at http://developer.android.com.
