Android TextUtils isEmpty vs String.isEmpty

Question

What is difference between TextUtils.isEmpty(string) and string.isEmpty?

Both do the same operation.

Is it advantageous to use

Answer 1

Yes, TextUtils.isEmpty(string) is preferred.

---

For string.isEmpty(), a null string value will throw a NullPointerException

TextUtils will always return a boolean value.

In code, the former simply calls the equivalent of the other, plus a null check.

return string == null || string.length() == 0;
