Android Studio: How to stop getting error marks on unused symbols

Question

In any code, i guess, there are variables/method/classes that are really not used and maybe just there for show/just in case.

Anyway, How do i set Android Studio to stop giving me the 'yellow' error stripe marks in the scrollbar for unused variables. Although, i don't want to stop getting warnings all together.

Answer 1

Fount it!

Right click the scroll bar > Customize Highlight Level > Configure inspections. You'll find an immense list, type-in the search field for unused then you'll see "Unused Symbol", unchecked it.

Answer 2

add SuppressWarnings annotation at the methods/variables/classes which are unused...

@SuppressWarnings("unused")
private String unusedString;

@SuppressWarnings("unused")
private void unusedMethod() {

}

@SuppressWarnings("unused")
private class UnUsedClass {

}
