Disable Intellij @Nullable on "implement methods" when base method is androidx @Nullable

Question

In Android Studio 4.2 beta 1, whenever I implement a method annotated with the androidx version of @Nullable, the IDE is automatically adding the jetbrains @Nullable annotation as well.

This is extremely annoying as it results in code like:

  @Nullable
  @org.jetbrains.annotations.Nullable
  @Override
  public String foo(@Nullable @org.jetbrains.annotations.Nullable String bar) {
    return null;
  }

Any way to prevent this?

Please tell what version of androidx annotations do you use? What default annotations do you have defined in Preferences | Build, Execution, Deployment | Compiler | Configure annotations? Thanks – Malvie

@OlgaKlisho AndroidX Annotations Version: 1.1.0. Preferences | Build, Execution, Deployment | Compiler exists, but there is nothing mentioned about annotations below that. – Thremmatology

Your issue seems to be the duplicate of youtrack.jetbrains.com/issue/IDEA-247941 and it should be fixed since IntelliJ IDEA 2020.2 Please see the workaround description youtrack.jetbrains.com/issue/… – Malvie

Thanks! oddly the configure annotations option is not in Android studio 4.2 beta 1. I believe the next release of Android Studio migrates to IDEA 2020, so it'll probably be there then. – Thremmatology

Answer 1

I ran into this problem and was able to fix it by going to Settings > Editor > Inspections > Probable Bugs > Nullability > @NotNull / @Nullable annotations. Then under Options, click the Configure Annotations button, select androidx.annotation.Nullable and androidx.annotation.NonNull from the respective lists, and press the checkmark to select them as the annotations.

Nice, this works. I think AS also fixed the default values at some point (currently using 2020.3.1-canary15) – Thremmatology

Very annoying issue this fixed it, thanks – Hotchpotch

Answer 2

As @jnmorris said, follow these steps :

Go to Settings > Editor > Inspections >

Find Java > Probable Bugs > Nullability Problems > @NotNull/@Nullable Problems

Click Configure Annotations button and check these items
