4 days practical workshop for up to 12 people.

This course shows how to port Android to a typical embedded hardware platform. It is intended for engineers who are starting out with a fresh Android implementation or who need to understand and modify an existing one.During the hands-on sessions attendees learn how to use the source code from the Android Open Source Project (AOSP) and go through the steps of implementing Android on a common development board with an ARM Cortex A series processor.

Layout

An essential part of the training are the lab sessions, which take approximately 50% of the time. We normally work in pairs using a modern development board. Each group will also need a laptop or desktop to run the system development tools. We will provide a bootable USB memory stick with an appropriate version of Linux and Android development tools, so there is no need to install Linux beforehand.

Who it is for

Software engineers and system architects

Training Course Prerequisites

  • A good understanding of the C language and familiarity with Linux development and command-line tools. A working knowledge of Java is useful.
