Description
Android is much more than a smartphone operating system. As the core of the Android Open Source Project, it serves as a multifaceted basis for a wide range of applications. AOSP’s key feature is its function as a platform for an open ecosystem
which enables the integration of third-party applications. AOSP already has a mature, comprehensively tested technology stack. It includes everything from connectivity and multimedia right through to highly sophisticated security mechanisms and a protected runtime environment for third-party applications. This means that you can focus on the core aspects of your business model when creating custom developments, instead of on the platform itself. This concept is proving an extremely interesting one, particularly for the automotive industry.
During this training course, we will dive deep into the AOSP functionality and examine the entire stack, including the Car System Service and Vehicle HAL. We will demonstrate how and at which points your own customizations or services can be
integrated, how a custom product variant can be defined, and how you can create your own emulators in order to test your customizations. Through numerous practical examples, inspired by real-life project requirements, this training course provides an
accessible introduction to the complex AOSP system development. Participants will also have plenty of opportunity to exchange information, ask questions, and help to shape the course content.
