Supporting Different Screen Sizes in Android

To support different screen sizes in Android, you can use the following techniques:

1. Use Density-Independent Pixels (dp)

• Use density-independent pixels (dp) instead of pixels (px) for dimensions in your layouts
• This ensures your UI elements scale appropriately for different screen densities
