G5	Android for Industrial System Control

Building friendly interfaces for industrial systems with Android

Objectives Discover the Android system architecture. Learn to configure and compile the Android sources to get a working system. Understand the Android SDK and NDK Learn how to build a simple application Learn the basics of man-machine Interface with Android Discover how to interface Java code and native code Explore the Android source code architecture The Android init process System services The Android Hardware Abstraction Layer Labs are conducted on i.MX6 or i.MX8 boards We use the last open source version of Android, as available on the board. For on-site trainings, if suitable Linux workstations are not available, we provide virtual machine images for VirtualBox; the only requisite is then a recent 64bit PC with at least 8Gb of RAM and 100Gb of free disk space.

Who should attend this course? Engineers that must develop Android applications to control industrial systems. Architects that want to understand the benefit they may obtain from using Android in their products. What you will be able to do after the training Install Android on an embedded platform Interface an Android platform with an external system Create a typical Android Embedded application. Prerequisite Basic Linux user experience Basic C (or C++) programming skills Due to the high degree of advanced Java techniques being used, good Java development skills are mandatory See our L4G - Java for Android course for quickly learning the necessary Java techniques

Course environment Printed course material (in English). One Linux PC for two trainees. One target Android platform (dual Cortex/A9) for two trainees External sensor hardware on an Arduino board connected in USB with the Android platform
