+\section{Install the Java JDK}
+
+The Android build system requires the Oracle Java6 JDK, that is too
+old to be bundled in Ubuntu. We'll have to fetch it from another
+source, and install it.
+
+To do so, we first need to add the repository that holds the JDK
+nowadays.
+
+\begin{verbatim}
+sudo add-apt-repository ppa:webupd8team/java
+sudo apt-get update
+\end{verbatim}
+
+Now, we can install the latest JDK version with the command:
+\begin{verbatim}
+sudo apt-get install oracle-java6-installer
+\end{verbatim}
