Rubin went on to say that Sun's president and CEO at the time, Jonathan Schwartz, was so excited about the idea of open sourcing Java that he wanted to "pick up the phone and call" Brin.

An undated presentation by Rubin and the Android team . It proposed that Sun become a founding partner of the Open Handset Alliance, the group of companies that supported Android when it launched. The presentation says Sun and Google would "engage in a co-development relationship."

The proposal included a three-year deal between the companies in which "Sun makes Java Open Source as part of [the] Android platform" and the companies work together to bring Android to market.

The proposal included a US$25 million to $50 million fee, which presumably would have been paid to Sun. In addition, if Google earned revenue from services running on Android, it was prepared to share that revenue with Sun.

One slide lists reasons for making the deal, including that it was critical to Google's open-source handset strategy, would dramatically accelerate its schedule and form an industry alliance to block Microsoft.
