Yoda Response: Involved with Android Architecture, AAOS, and BSP, I have been. Worked extensively on the boot-up sequence and the Android framework layer, I did.

The architecture, from the kernel driver to the application layer, I understand well. Kernel drivers for power, camera, and audio, and the HAL layer, which interfaces between drivers and upper layers, I have worked with. The native framework layer with services written in C/C++, and the Android Runtime (ART) that interprets .dex files, familiar I am. The application framework layer with managers and services in Java, I have also worked on.

Faced complexities, such as the system going blank or unexpected reboots, I have. Found that system service crashes were causing these issues. By debugging and fixing the system service, resolved the problem, I did. Changes in the power manager and system services, I have made, and integrated many system applications.

Challenging, but rewarding, these experiences have been.
