Android is an open-source software stack for mobile devices, and a corresponding open-source project led by Google. We created Android in response to our own experiences launching mobile apps. We wanted to make sure that there was no central point of failure, so that no industry player can restrict or control the innovations of any other. That’s why we created Android, and made its source code open.
Google’s Vic Gundotra at the keynote for I/O 2010:
“If Google didn’t act, it faced a draconian future where one man, one phone, one carrier were our choice. That’s a future we don’t want. … So if you believe in openness, if you believe in choice, if you believe in innovation from everyone, then welcome to Android.”
