مطلبی جالب در ویکیپدیا خواندم که حتما بخوانید:

Android's source code is released by Google under open source licenses, although most Android devices ultimately ship with a combination of open source and proprietary software, including proprietary software developed and licensed by Google.[3] Initially developed by Android, Inc., which Google bought in 2005,[16] Android was unveiled in 2007, along with the founding of the Open Handset Alliance – a consortium of hardware, software, and telecommunication companies devoted to advancing open standards for mobile devices.[17]

Android is popular with technology companies which require a ready-made, low-cost and customizable operating system for high-tech devices.[18] Android's open nature has encouraged a large community of developers and enthusiasts to use the open-source code as a foundation for community-driven projects, which add new features for advanced users[19] or bring Android to devices which were officially released running other operating systems. The operating system's success has made it a target for patent litigation as part of the so-called "smartphone wars" between technology companies

بسیار جالب است که بدانید اندروید بر اساس لینوکس (بله لینوکس رقیب دیرینه ماکروسافت) کرنل است که گوگل آن را توسعه داد و شاید بتوان گفت اگرچه در فروش سیستم عامل های کامپیوتر، pc و لپتاپ در مقابل ویندوز مایگر.سافت شکست خورد اما بدون شک در بازار موبایل گوی میدان را از دست ویندوزفون ها ربود و رقابتش با آی او اس (سیستم عامل آیفون) بالا گرفته است.
