Hint for @NonNull not working by pressing ALT+ENTER

Question

I am getting problem in shortcut of Auto Insert code: ALT+ENTER

Not annotated parameter overrides @ParametersAreNonnullByDefault

Inspection info: This inspection reports problems related to @Nullable and @NotNull annotations usage configured in Constant conditions & exceptions inspection.

I know that by pressing ALT+ENTER we are getting option as below:

And It will annotate automatically by press ENTER.

But I am getting following options (There is no option to annotate directly)

Why the above image not showing option to Annotate directly.

I am using Android Studio:

Android Studio 3.3.2
Build #AI-182.5107.16.33.5314842, built on February 16, 2019
JRE: 1.8.0_152-release-1248-b01 amd64
JVM: OpenJDK 64-Bit Server VM by JetBrains s.r.o
Linux 4.18.0-16-generic

Issue:

I have one project in PC-1 named "UserApp" created using Android Studio 3.3.1, Another Project "DriverApp" in PC-2 created using same version.

This annotation problems come up with both project but In "UserApp" its solved by updating Android Studio 3.3.2

Now I am coping "DriverApp" in PC-1 but and compiling in Android Studio 3.3.2 but getting same error as previously I got.

How can I rebuild "DriverApp" project so I get that annotation working?

I have tried:

Restart, Invalidate cache, and Restart
Build Project
Clean Project

When I tried to add annotation in Android studio 3.4 , it automatically added dependency `implementation 'org.jetbrains:annotations-java5:15.0'` . So try adding this dependency and check — Manohar, Mar 11 '19 at 07:19

I found answer as I have implemented following steps:

After pressing ALT+ENTER, Click on right arrow of "Inspection '@NotNull/@Nullable problems'" and then Run inspection on...

You will be prompted for Scope of Inspection. That should be Whole Project.

In that you will came to know how many places need to change. By clicking on "AndroidX Annotation", It will use annotation for AndroidX.

This problem occurred after Migration of AndroidX.

Hope it will helps you.

Settings > Build, Execution, Deployment > Compiler > Annotation Processors. Tick 'Enable annotation processing'.

File | Other Settings | Default Settings, navigate to the compiler settings, annotation processing and enable this option before importing the project.' In android studio 3.3 there's change in schema you can find it here and it works in new projects only after change done,its working in my current project also – Richa Shah Mar 11 '19 at 06:45
In that I am just getting option for `SDK Location` only. – Pratik Butani Mar 11 '19 at 06:47
