One complex problem I tackled involved developing a dynamic calendar feature for the Sacramento Kings NBA team application. The challenge was to create an interactive calendar where each date could expand to display events, games, live scores, and video icons.

To address this, we utilized a combination of GridLayout and RecyclerView. Each date was represented as an item in the RecyclerView, allowing for efficient handling of large data sets. This implementation required careful management of UI states to ensure smooth transitions between expanded and collapsed views.

We adhered to several best practices to ensure code quality and maintainability:

1. **Architecture**: We employed the MVVM (Model-View-ViewModel) architecture, which helped separate concerns and made the codebase more modular and testable.

2. **Design Patterns**: We implemented design patterns such as Singleton for managing instances and Factory for creating complex objects, enhancing code reusability and manageability.

3. **Code Quality Tools**: We utilized tools like Lint and SonarQube to analyze the code for potential issues and ensure compliance with coding standards, helping maintain a clean and efficient codebase.

4. **Unit Testing**: We wrote extensive unit tests using JUnit and Mockito to ensure our code was reliable and free of bugs, which also helped catch regressions early in the development process.

5. **Documentation**: We thoroughly documented our code, making it easier for other team members to understand and contribute. This included inline comments and external documentation for complex algorithms and data structures.

6. **Performance Optimization**: We used Android Profiler to monitor CPU, memory, and network usage, which helped us identify and resolve performance bottlenecks, ensuring that the calendar feature was responsive and efficient.

By following these practices, we created a robust and maintainable solution that met the requirements and provided a seamless user experience. The project was a valuable learning experience and reinforced the importance of adhering to best practices in software development. Thank you.
