How do you approach app development for devices with varying display resolutions and pixel densities?

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.
