I download the android source code here : https://github.com/android
But my problem is how to know the api version of each branch, like for exemple for the branch:
- gingerbread-release
- ics-mr0-release
- ics-mr1-release
- jb-release
- kitkat-release
- lollipop-mr1-release
- lollipop-release
- marshmallow-mr1-release
- marshmallow-mr2-release
- marshmallow-release
- nougat-release
- etc..
