One of the projects I worked on involved customizing Android for specific hardware configurations in the infotainment system of Scania Trucks. To ensure compatibility with AOSP and AAOS specifications, we diligently followed the latest AOSP documentation and guidelines, aligning our customizations with standard practices. We developed AIDL services to facilitate communication between various components and to integrate with car-specific libraries and drivers. Additionally, we tailored the bootloader animation and system UI components, such as the status bar, notification panel, and input methods, to meet the hardware requirements. We also implemented SELinux policies to manage read/write permissions and enhance the security of our custom components.

To monitor performance and resource management, we utilized Android Profiler to track RAM usage, battery performance, and overall system health. We established a CI/CD pipeline to ensure continuous integration and development, which allowed us to identify issues early through automated testing and validation.

For testing and validation, we conducted extensive assessments using the Compatibility Test Suite (CTS) to confirm that our customizations were compatible with AOSP specifications. We also customized the Human-Machine Interface (HMI) by modifying AOSP components like the bootloader, framework, and UI/UX elements to address the specific needs of the hardware.

By following these steps, we ensured that our customizations were robust, secure, and fully compatible with AOSP and AAOS specifications, providing a seamless user experience on the specific hardware.
