G5 Android for Industrial System Control

Building friendly interfaces for industrial systems with Android

formateur
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
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
