A couple questions:

• Should we wait until Manny's PR is merged so there will be fewer public classes/methods to document?
• I'm guessing we need to update this periodically as we change the public surface of our API. How will we remember to do this next time?

[rachaprince]

Good callout, let's wait for Manny's PR to land.

The second question is also a good one. It seems like the api-information test should run on every PR. I wonder if there is a configuration setting that should be fixed in this repo. I'll ask a question to the Firebase Android Core team

Thanks @rachaprince for fixing this. I didn't have time to work on #3213 any further. I'll close that.

[rachaprince]

Looking at the public api files generated by the script, I think there are still some places where we will want to reduce the visibility of methods and classes

[rachaprince]

Closing this in favor of #3235, which limits the number of public classes and methods
