there are so many libraries trying to be helpful in the Android ecosystem that it's sometimes hard to know which ones to employ, which ones are worth the time and effort to learn.<p>this tool seems like it provides some useful data to help developers answer that question for their projects.<p>that said, i think some of the most interesting info is about the libraries that are <i>not</i> published by Google. it might be neat to have an option to filter those out of the results.
