By TRULY empty, I mean no ways to cheat it. there are many websites on the internet offering empty characters in order to cheat the system and send an empty message. I want to block every single way that this could happen. MY QUESTION IS: Is there any function in android studio that prevents such things from happening? a function which checks both if the string is empty and if it doesn’t contain any empty characters?? or do I have to do it manualy?
You can use isBlank to test for the most common whitespace characters (or emptiness), but you’ll have to check the exotic ones manually I’m afraid.
