Should use “sp” instead of “dp” for text sizes

Question

When I use

android:textSizes=\"20dp\" 

in my XML for a textView, I got a warning \"Should use \"sp\" instead of <

Answer 1

As @GiruBhai shared,it is more convenient to use sp instead of dp for the text size since it can be changed -unlike dp - according to the user's preferences.Which may be fulfilling your users needs better.
