What is the structure of the Android source repository at Google Git?

I am familiar with this android architecture model:enter image description here

But when I browse android repository at google git I just can't figure out exactly what files should exist in which folder. What exactly is the folder structure of the android git? Also another question, Is there any specific reason why 'Core Libraries' shown in picture inside 'ANDROID RUNTIME' block sits below 'APPLICATION FRAMEWORK' block? Keeping in mind how apps interact with 'Core Libraries' they should sit beside 'APPLICATION FRAMEWORK' block not below it.
