To ensure Android app compatibility with different screen sizes and resolutions, follow these steps:
1. Use density-independent units (dp or dip) for dimensions instead of pixels.
2. Implement responsive layouts using ConstraintLayout, RelativeLayout, or LinearLayout to adapt UI elements to various screen sizes.
3. Utilize the “wrap_content” and “match_parent” attributes for width and height properties to adjust views dynamically.
4. Create alternative resource folders (res/layout, res/drawable, etc.) for specific screen configurations (e.g., small, normal, large, xlarge).
5. Employ vector drawables or 9-patch images to maintain image quality across different resolutions.
6. Test your application on multiple devices/emulators with varying screen sizes and densities.
