Sample interview questions: How do you approach app development for devices with varying display resolutions and pixel densities?
Sample answer:
Adaptive Design Principles:
- Responsive Layouts: Use flexible layouts that adjust to different screen sizes. Employ percentages, rem, or em units to ensure elements scale proportionally.
- Fluid Images: Utilize SVGs or images with multiple resolutions to ensure they remain sharp and crisp at different pixel densities.
- Dynamic Text Scaling: Adjust font sizes based on screen dimensions to maintain readability and accessibility.
Multi-Resolution Assets:
- Size-Specific Resources: Create separate asset folders for different display sizes, ensuring optimal image quality for each resolution.
- Vector Graphics (SVGs): Use vector graphics that can scale seamlessly to any screen size without pixelation.
- Resolution-Independent Images: Create images that are resolution-independent, such as PNGs with transparent backgrounds.
Testing and Optimization:
- Test on Multiple Devices: Thoroughly test your app on a variety of devices with different resolutions and pix… Read full answer
