After many hours, I finally uninstalled Android Studio, delete all Android directory, clean registry and reinstall Android Studio stable version.

you can just change the Kotlin version to something else and then gradle sync again This will solve the issue

you will find it in build.gradle file(project)

    ext.kotlin_version = "1.5.10"  //I used this 

you can also roll back to your previous version. If you want this should not recreate the issue.

Try it:

File --> settings --> Plugins --> Android ButterKnife Zelezny --> disenable

Kotlin version 1.4.10 magically stopped working in the IDE.

The problems are not related to the IDE version but rather to the integration of the kotlin plugin and the IDE.

kotlinVersion = '1.5.10'

classpath 'com.android.tools.build:gradle:4.2.2'

Then Sync Project and Compile.

Finally you can see that the problem of Analyzing disappears and the IDE becomes intelligent again.

It is possible that after updating kotlin you have minimal errors in other libraries so you also have to update or fix them (I happened with Room)

The one solution that worked for me (working in Canary 2021.1.1) was to completely uninstall the Kotlin plugin from Android Studio, restart, let Android Studio install it automatically, and then everything worked again.

The root cause of this issue was that Android Studio "accidentally?" updated Kotlin plugin to an M1 version (I'm on x64), namely 211-1.5.30-M1-release-141-AS7442.40, when updating the plugin. I'm not sure why, but from now a check of what is going to be updated in Canary seems mandatory to avoid these kind of stuff to happen.

This solution is 100% working for the above issue

 ext.kotlin_version = "1.5.21"

 classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"

This is a looming AS IDE issue correlated with the Kotlin plugin, Have tried literally every answers here with tooth and nail, nothing worked. There were chains of errors. Finally removing the android studio cache manually only worked for me %USERPROFILE%\AppData\Local\Google\AndroidStudio2020.3. Artic fox sucks!

You may also try to update the Kotlin plugin to the latest if possible and see if it makes any difference.

In my case, I just update the dependency "androidx.core:core-ktx:1.3.2" to "androidx.core:core-ktx:1.6.0". And it's gone, working normally

Android Studio -> File -> Invalidate Caches and Restart

Nothing else helped me.

It appears that the Kotlin plugin was, indeed, the culprit.

Today (24 May 2021), a new version was released 1.5.10, and as soon as I installed it, everything went back to normal.

Synopsis: After upgrading from version 1.4.32 of Kotlin plugin to 1.5.0, code inspection, completion, linking to sources, javadocs, etc. all stop working (stuck at "Analyzing..." as the images here and here show), and only return for a few seconds/minutes when sth triggers a new analysis (eg. a gradle build, commit, loading new files, etc).

History of the plugin updates for reference can be found here

From my project I deleted the files

.idea/gradle.xml
.idea/workspace.xml

and it solved it for me.

Seems to be that I had previously configured the project's gradle incorrectly and even after several reinstalls I wasn't getting any luck.

disable Compose plugin. the only way work for me.

If you are using

• Jetpack Compose 1.0.5 (haven't tested with 1.0.0-1.0.4 but they should work too)
• Java 11
• Kotlin 1.5.31 (tested 1.5.10 working too)

the other answers don't work

What works is the following in your project build.gradle:

tasks.withType(org.jetbrains.kotlin.gradle.tasks.KotlinCompile).configureEach {
        kotlinOptions {
            jvmTarget = "11"
            useIR = true
            freeCompilerArgs += [
                    "-Xallow-jvm-ir-dependencies",
                    "-P",
                    "plugin:androidx.compose.compiler.plugins.kotlin:suppressKotlinVersionCompatibilityCheck=true"
            ]
        }
    }

(compose compiler was blocking Kotlin compiler from completing jobs)

and Invalidate Caches & Restart

I just update the Koltin version to 1.5.20 and it works!!

this issue comes from plugins

1- update plugins

2- step by step disable plugins to find incorrect plugin

3- as advance people please report issue to providers for solve the problem

in Arctic Fox version (2020.3.1) I fixed it by updating Gradle Plugin version 7.0.0.
