Ever since Froyo (Android 2.2), Google's Android OS has supported syncing Microsoft Exchange accounts using the ActiveSync protocol. I am trying to find Android's implementation of the ActiveSync protocol within the Android code-base.
Does anyone know where ActiveSync is implemented in Android? I have been rummaging around the GitHub repository but cannot find it.
Right here, enjoy.
[EDIT] - if there are issues accessing the link above, the source is also on omapzoom.org. To see individual code files there, navigate to a "tree" link for any of the commits and dig down into the src folders. Here's an example.
