In a recent project at Harman, I had the opportunity to work with Kotlin for Android Automotive development. We encountered several challenges during the build and deployment process, particularly with fast boot and reboot issues. Debugging proved to be quite difficult due to the absence of direct debugging tools, so we relied heavily on logs to identify and resolve problems. To enhance our troubleshooting efforts, I implemented a comprehensive logging mechanism that captured detailed information. We carefully analyzed these logs to accurately pinpoint and address the issues we faced. Through persistence and a systematic approach, we successfully overcame these challenges.
