I am just one of the people who help. Anyway, the android pages are a mess. I wont update them myself since I only update things I actually have experience with and understand.
I have been assembling some posts on fixing this page,

But still am not comfortable with actually implementing anything related to it.
I have @jayfella comments saved, but am unsure if they are complete since I do not use google anything if I can help it.
Edit: Feel free to crazy and fix anything you wish… You can follow the link @jayfella has and on it you will find detailed explanations on how to contribute.
