The answer is right there: What is the difference between "px", "dp", "dip" and "sp" on Android?
pixels is the exact number, and dip is dynamic: better to keep the view you want on any type of screen
Problem
Why did I have this Alert message in my xml layouts in android the message is Avoid using "px" as unite, use "dp" instead
