When I tried to install the latest Android ADT in my ubuntu 13.10 laptop, I found that annoying "R cannot be resolved" bug. And it also reports that aapt cannot find or open libstdc++.so.6and libz.so.1.
After I search the web, here is the solution I found:
sudo apt-get install lib32ncurses5 lib32stdc++6 sudo apt-get install lib64z1-dev
