This week's book giveaway is in the Design forum. We're giving away four copies of Experimentation for Engineers: From A/B testing to Bayesian optimization and have David Sweet on-line! See this thread for details.
I have been trying to add android-support-v7-appcompat to my android project and found that there were no files in src! I also checked with another sdk and the src folder was empty there too.
So is it supposed to be empty or have I done something wrong.
If I have done something wrong please advise how I should get the files
