Working with AOSP has presented several challenging integrations, but one particular instance stands out. We were tasked with migrating an existing project from Android 8 (Oreo) to Android 10 (Q). This involved significant changes, including transitioning from HIDL to AIDL for hardware interface definitions. The migration required us to ensure that all hardware components and custom kernels were compatible with the new AIDL framework. This complex process demanded thorough testing and validation of each component.

The setup itself posed a major challenge, as AOSP requires substantial disk space and time for installation. Patience and meticulous planning were crucial during this phase. We extensively used ADB tools to test hardware components and ensure they functioned correctly with the new system.

Another challenge was ensuring compatibility across different screen sizes. We had to adapt the UI to work seamlessly on both small and large screens, which involved significant adjustments and testing to guarantee a consistent user experience.

Additionally, we converted existing Java code to Kotlin, which required careful handling of annotations to preserve all functionalities. We also transitioned from traditional layouts like RelativeLayout to Jetpack Compose, necessitating a complete overhaul of the UI components.

To manage these changes effectively, we implemented feature flags and maintained comprehensive documentation. This approach allowed us to track changes and ensure that any new features or modifications were well-documented and easy to understand for future developers.

We conducted regular code reviews and established versioning protocols to maintain code quality and stability. This helped us identify potential issues early and ensured that the project remained on track.

Overall, the successful integration of AOSP required a combination of technical expertise, thorough testing, and effective documentation. These efforts ensured that we could deliver a stable and high-performing product that met the project's requirements. Thank you.
