Can you explain the differences between px, dp, and sp units in Android development?

Android uses different units of measurement to ensure a responsive and readable interface on various devices:

• px (pixels) — these are actual screen pixels. Direct use is not recommended because pixel density varies across devices.

• dp (density-independent pixels) — units independent of pixel density. They scale depending on the screen density so that interface elements appear the same size on different devices.

• sp (scale-independent pixels) — similar to dp, but additionally consider the user's font size settings. Used for text sizes so that text scales according to user preferences.

Example:

• For setting button size, it is better to use dp.
• For text size — sp.

This ensures usability and interface adaptability.
