Android HAL (Hardware Abstraction Layer) is one of the lower layers in the Android OS software stack (right above the Linux kernel). It is a hardware specific implementation that provides an interface between system services (e.g., camera software) and the hardware drivers for that service (e.g., camera driver).
This instructor-led, live training (onsite or remote) is aimed at developers who wish to write HAL interfaces to enable Android applications to talk to the underlying hardware.
By the end of this training, participants will be able to:
- Set up the development environment needed to start HAL development for Android.
- Implement a HAL interface to enable Android services to communication with hardware device drivers.
- Understand how a HAL module is loaded by an Android system.
- Develop, test and debug HAL code iteratively using an Android emulator.
- Load and deploy HAL modules onto a physical Android device for real-world testing.
- Understand and implement HAL's re-architectured HIDL on Android 8.0 devices.
Format of the Course
- Interactive lecture and discussion.
- Lots of exercises and practice.
- Hands-on implementation in a live-lab environment.
