What am I missing? This doesn't make any sense:
Why is TextUtils.isEmpty(null) returning false?

isEmpty(CharSequence str) Returns true if the string is null or 0-length. static boolean. isGraphic(CharSequence str) Returns whether the given CharSequence contains any printable characters.
Yes, TextUtils. isEmpty(string) is preferred. TextUtils will always return a boolean value. In code, the former simply calls the equivalent of the other, plus a null check.
I faced this same issue while writing my unit test. The problem was I had following setting in my Gradle:
testOptions {
unitTests.returnDefaultValues = true
}
By default android code returned default value, while running my unit tests. Just get rid of that and you should be fine.
