Kim Kulish/Corbis Andy Rubin, a former Google executive and the inventor of the Android operating system, left the search giant after having an "inappropriate relationship" with a subordinate and then concealed secret payments related to his departure from his wife for several years, according to a court filing made public Tuesday.

The New York Times reported in October that Google paid Rubin $90 million after company co-founder Larry Page asked for his resignation
