Even though Google doesn't publicly disclose its financials regarding the Android OS, the trial currently going on between Google and Oracle has been indirectly changing that. During one of the recent trial proceedings, the Judge in the case shared that Google actually lost money for every quarter in 2010 on their Android OS. He didn't give specific figures, but after reading aloud from one of Google's financial documents he finished with, "That adds up to a big loss for the whole year."

This is relevant to the case because "Oracle contends that Google should not be able to deduct certain Android expenses for the purposes of copyright damages in the case. However, Google spokesman Jim Prosser said Oracle misrepresented its financial numbers."
