Software

Android is a software stack for mobile devices that includes an operating system, middleware and key applications. This beta version of the Android SDK provides the tools and APIs necessary to begin developing applications on the Android platform using the Java programming language.

Android is a software platform and operating system for mobile devices, based on the Linux kernel, developed by Google and later the Open Handset Alliance.[1] It allows developers to write managed code in a Java-like language that utilizes Google-developed Java libraries,[2] but does not support programs developed in native code.[3]

The unveiling of the Android platform on 5 November 2007 was announced with the founding of the Open Handset Alliance, a consortium of 34 hardware, software, and telecom companies devoted to advancing open standards for mobile devices.[4] Google has pledged to make most of the Android platform available under the Apache free-software and open source license.[5]
Over the past year, we announced Android, released several SDKs (eventually resulting in the 1.0 SDK), gave out the first half of the $10,000,000 prize money for the Android Developer Challenge, and prepared the first Android-powered device for users. Tomorrow, the T-Mobile G1 goes on sale.

But today, we're making what might just be the most exciting announcement of all: we and our Open Handset Alliance partners have now released the source code for Android. There's a huge amount of code and content there, so head over to http://source.android.com/ for all the details.

I'd like to offer a huge thank you and congratulations to my colleagues and the Alliance partners for what I hope will be a red-letter day for the open source community, and openness in the mobile industry.
