How do I know if a certificate authority is going to be trusted on a particular version of the Android SDK?

I can't find a list of authorities per Android SDK version anywhere. Most advice suggests running some code on a mounted device to determine the list of trusted root authorities for that device. This is simply not acceptable. If we're testing against a certain version, I need to know for that version, and each vers开发者_Python百科ion above, what certificate authorities can we use? In particular, we need the CA to be trusted on Android 2.0+.
