If you are running Android Studio in Linux Mint / Ubuntu 64bit and you just updated to the latest Android Studio version, you might get the following error:
/home/esilva/IDEs/android-studio/sdk/build-tools/19.1.0/aapt: error while loading shared libraries: libz.so.1: cannot open shared object file: No such file or directory

To fix it just install ia32-libs from your Synaptic Package Manager
This should fix it…
Happy Coding!
