I have contributed to the development of AOSP and AAOS, and I would like to share an example of my work. I was involved in customization and utilized the Android Interface Definition Language (AIDL), a powerful tool for inter-process communication (IPC). AIDL enables the definition of interfaces that facilitate client-server communication.

One specific instance I recall involved implementing audio settings customization. I used AIDL to create steps for a callback interface, which I then implemented in a custom class to manage changes to the audio settings. For example, I needed to mute the currently playing track. By using the AIDL-generated steps in my custom class, I was able to call the method to mute the audio, ensuring smooth IPC by leveraging the underlying Linux features.

This approach proved to be effective, allowing me to customize and maintain AOSP components, enhancing functionality and ensuring seamless communication between applications.
