I have extensive experience with both Java and Kotlin in Android development. I began my journey with Java while working on an e-commerce application, and more recently, I have transitioned to using Kotlin in the automotive sector.

In my earlier projects, I utilized Java for various aspects of Android development, including thread management, where I applied Java's threading model to handle background tasks and UI updates. I also implemented network operations using libraries like Retrofit and managed JSON parsing with Gson. Additionally, I built complex UI components to ensure smooth interaction with the backend.

In my recent projects, I have leveraged Kotlin's advanced features to enhance development efficiency and code quality. I used Kotlin Coroutines for managing asynchronous tasks, which simplified the code and improved readability compared to traditional threading models. Kotlin's null safety features helped reduce null pointer exceptions, making the code more robust. I also utilized extension functions to add functionality to existing classes without modifying their code, which improved modularity and readability. Furthermore, higher-order functions and lambdas allowed for more expressive and concise code, especially in scenarios involving callbacks and event handling.

One notable project where I utilized advanced features of Kotlin was the development of an automotive HMI application. In this project, I implemented coroutines for handling network calls and background tasks, ensuring a smooth and responsive user interface. I used extension functions to simplify the manipulation of UI components, making the code cleaner and more maintainable. I also leveraged Kotlin's sealed classes to manage different states of the UI, such as loading, success, and error states, in a type-safe manner.

By utilizing these advanced features of Java and Kotlin, I was able to develop robust, efficient, and maintainable Android applications. This experience has provided me with a deep understanding of both languages and their respective strengths in the context of Android development.
