I have seen many tutorials which suggest cloning of andengine and its extensions by using Mercurial.
The url is https://code.google.com/p/andengine. However when I clone using this URL I get a single README file telling me that everything has moved to https://github.com/nicolasgramlich/AndEngine
However I am not able to clone from here. How should I clone the files
Any help will be appreciated.
They moved to Github so you need to use Git to get the files. See Installing Git for more info.
