ViewBinding with Java11, AndroidStudio always shows error (but runs without any problem)

Question

I notice that with Java8 there is no problem with viewBinding in AndroidStudio (Arctic Fox).

compileOptions {
    sourceCompatibility JavaVersion.VERSION_1_8
    targetCompatibility JavaVersion.VERSION_1_8
}
buildFeatures {
    viewBinding true
}

However, once I set compileOptions to JavaVersion.VERSION_11, AndroidStudio always falsely shows viewBiding(s) errors though it can compile and run with no problem.

I tested this with a fresh new project in AndroidStudio ArcticFox. It suggests to import the class. After imported, it says Package not found:

Is this AndroidStudio's bug, or are there any misconfiguration about Java compiler setting in my AndroidStudio?

All I did something particular was JavaVersion.VERSION_11.

Maybe you need to update the Gradle plugin. Faced such kinds of issues due to Gradle plugin on lower AS — Sachin, Jul 30 '21 at 06:23
@Sachin I think Gradle plugin is recent: `classpath "com.android.tools.build:gradle:7.0.0"` — hata, Jul 30 '21 at 06:33
Still happening today -.- The project can be built and launched on a physical device but it show the annoying red message. — ieselisra, Oct 10 '21 at 08:25

As google's support answered: This issue has been fixed and landed in BB canary 8. It is specific to Java 11.

Thank you. FYI, I searched about Bumblebee canary then I found this issue tracker: [View Binding not working with Java 11](https://issuetracker.google.com/issues/180946610?pli=1). I'll wait next stable update. – hata Aug 11 '21 at 11:18
With stable Bumblebee the problem has actually been fixed! – hata Jan 27 '22 at 11:26

remove the import line from your project and import it again by pressing Alt+Enter then inform me

import com.myapplication.databinding.ActivityMainBinding;

public class MainActivity extends AppCompatActivity {   

ActivityMainBinding binding;
protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);


        binding = ActivityMainBinding.inflate(getLayoutInflater());
        View view = binding.getRoot();
        setContentView(view);

}

}

I imported the class again. But the imported class definition is red colored `Package not found` error. – hata Jul 30 '21 at 07:44
make sure your package name is correct in class definatination??? otherwise viewBinding is right – Muhammad Mubashar Hussain Jul 30 '21 at 07:51
It does not solve the problem of this issue. – t0m Aug 16 '21 at 07:20

I had this issue, and I did the following:

Run the gradle updater
OR
open the terminal and run gradlew help --scan, it will generate a report that tells will what you should edit before migrate to Gradle 7.0
open your gradle.properties and distributionUrl to https\://services.gradle.org/distributions/gradle-7.0.2-bin.zip
Go to your Project build.gradle and set the classpath to com.android.tools.build:gradle:7.0.0.
Sync with Gradle FIles and rebuild your project.

Thank you for your information. My test project is a newly created project and it uses Gradle 7.0 (gradle-wrapper.properties: gradle-7.0.2-bin.zip) from its creation. – hata Jul 31 '21 at 14:50
