One significant project where I tailored Android for specific hardware configurations was for the Scania Trucks navigation system. To ensure compatibility with AOSP and AAOS specifications, I undertook several key steps.

I strictly adhered to AOSP guidelines and documentation to ensure that all customizations met the latest standards and features. I developed custom services using AIDL to integrate with car-specific libraries and drivers in the Hardware Abstraction Layer (HAL). Additionally, I customized the bootloader animation and system UI components, such as the status bar and notification bar, to align with the specific hardware requirements. I also enhanced input methods and resource management to optimize performance for the hardware.

To manage read/write permissions and ensure secure access to hardware resources, I implemented SELinux policies. I conducted rigorous compatibility testing using the Compatibility Test Suite (CTS) to ensure that the customizations did not disrupt any AOSP or AAOS specifications. Utilizing continuous integration and continuous development pipelines allowed me to automate testing and deployment, helping to catch any issues early and ensuring that the application remained stable and compliant.

For performance and optimization, I used Android Studio Profiler to monitor RAM usage, battery performance, and overall system performance. I conducted extensive UX/UI testing to ensure a seamless user experience. Furthermore, I customized the Human-Machine Interface (HMI) by modifying AIDL interfaces and AOSP components to create a user-friendly and efficient interface for truck drivers.

By following these steps, I ensured that the customized Android system was fully compatible with AOSP and AAOS specifications while meeting the specific needs of the hardware.
