While setting up continuous integration on Ubuntu Server 16.04 for my Intoxication Calculator Android Application I experienced the following error:

> com.android.ide.common.process.ProcessException: Failed to execute aapt

This is due to missing 32bit dependencies which need to be installed in addition to the Android SDK. These libraries can be installed by executing:

$ sudo apt-get install lib32gcc1 libc6-i386 lib32z1 lib32stdc++6

I’ve had to install these libraries in the past on my Lubuntu development machines.
