Yoda Response: Certainly, Avi. Designing user interface components for the Android platform, especially system-level UI elements and custom views, has been a significant part of my experience. Here’s an overview:

1. **Understanding Requirements**: I start by collaborating closely with UX designers to understand the complete requirements and ensure that the design aligns with user expectations and best practices.

2. **Custom Views and Reusable Components**:
   - **Custom Views**: Developed custom views for reusable components such as custom progress bars, buttons, and drawing views. This involves extending existing view classes and overriding methods like `onDraw` to create unique UI elements.
   - **RecyclerView**: Utilized RecyclerView for efficient display and management of large data sets, implementing custom adapters and view holders.

3. **System UI Customization**:
   - **Overlay and Notification Bar**: Customized system UI elements such as overlays and the notification bar to enhance the user experience.
   - **Custom Dashboards and Widgets**: Designed custom dashboards and widgets, including launchers and picture-in-picture modes, to provide a seamless and interactive user interface.

4. **Performance Optimization**:
   - **Layout Optimization**: Focused on optimizing layouts by avoiding nested layouts and using ConstraintLayout for complex designs. Implemented view caching mechanisms to improve performance.
   - **Hardware Acceleration**: Managed hardware acceleration settings to ensure smooth rendering of custom views.

5. **System-Level UI Elements**:
   - **Split Screen and Multi-Window Support**: Developed interfaces that support split-screen and multi-window modes, ensuring compatibility across different devices and screen sizes.
   - **Animation and Interaction**: Implemented custom animations and interaction patterns to enhance the user experience, using ObjectAnimator and other animation frameworks.

By focusing on these aspects, I ensure that the user interface components are not only visually appealing but also performant and user-friendly, providing a consistent experience across all devices and screen sizes.
