How to remove warnings of nullable in Android?

Question

I'm using annotations library supported by Android. It is useful for checking NullpointerExceptions. But, it also annoying if I checked the variable if it is null.

In this case:

@Nullable String value; boolean isValid(String target) { return (target != null && target.length() > 0); } void test() { if (isValid(value)) { Log.d("TEST", value); // Do something. } }

In above code, I already checked if 'value' is null, but still got the warning of "It maybe produce NullPointerException".

Is there some annotations that I checked null-type in this function?

Why not initialize the String value to an empty string in the constructor or at declaration itself? — vishwarajanand

You can use the annotation:

@SuppressWarnings("ConstantConditions")
