How do I sort/filter Google Code projects by stars? - google-code

Question

I would like to know what projects hosted on Google Code that have the most stars, especially when searching by label, like this:
https://code.google.com/hosting/search?q=label%3aAndroid

Answer 1

Sort by stars is not supported on the project search page. Was able to write some page scrapping code to get the required information.
Hope it helps.

System.out.println("Total projects:" +projects.size());
for (Project project : projects) {
System.out.println(project.url + ":" + project.stars);
}
}
}
class Project {
String url;
String stars;
}

Answer 2

I would have say use &sort=stars as they do in the support of google code but it doesn't work well. I'm not sure it's possible unfortunately...
