Is there a android developer page that lists all of the trusted root CAs?
I know I can just pull the file, and list them using keytool - looking for a published web page
I haven't found an official page. However, here is shown how to get the list of trustes certs from an android device: http://www.andreabaccega.com/blog/2010/09/23/android-root-certification-authorities-list/
There are also all certs published which were found on an that particular Android 2.2 Froyo.
Coming too late to the party, but still... Although it is not an official document, you can find few lists of system trusted certificates taken from Android devices here.
In Jelly bean you can find the trusted CA list by navigating to
Settings -> Security -> Trusted credentials.
