Firebase – The binary version of its metadata is 1.7.1, expected version is 1.5.1. How to Solve?

I connected firebase and I got this error, how can I fix it? (Class ‘com.google.firebase.auth.ktx.AuthKt’ was compiled with an incompatible version of Kotlin. The binary version of its metadata is 1.7.1, expected version is 1.5.1.)

build.gradle

buildscript {
    ext {
        compose_version = '1.1.0-beta01'
    }

    dependencies {
        classpath 'com.google.gms:google-services:4.3.13'
    }
}// Top-level build file where you can add configuration options common to all sub-projects/modules.
plugins {
    id 'com.android.application' version '7.2.1' apply false
    id 'com.android.library' version '7.2.1' apply false
    id 'org.jetbrains.kotlin.android' version '1.5.31' apply false
}

task clean(type: Delete) {
    delete rootProject.buildDir
}

    Try downgrading kotlin version from 1.7.1 to 1.5.1. Your current version is causing the issue as firebase auth dependency is not compatible with your current kotlin version.

    Recently i had same issue,

    I fixed with below steps.

    Project Gradle

     classpath 'org.jetbrains.kotlin:kotlin-gradle-plugin:1.7.10' 
 or 
 id 'org.jetbrains.kotlin.android' version '1.7.10' apply false

    App gradle

    implementation "org.jetbrains.kotlin:kotlin-reflect:1.7.10"

    You can find more details on the below thread.

    Try this. It works.

    buildscript {
    ext.kotlin_version = '1.7.20'
    repositories {
        google()
        mavenCentral()
    }

    dependencies {
        classpath 'com.android.tools.build:gradle:7.2.2'
        classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
    }
}

    Because of the Kotlin version of your Gradle project. Gradle forces and old version of Kotlin. So the solution is:

    Firstly, you need to update your Kotlin plugin in Android Studio to the latest version.

    Second, go to /android/build.gradle and use this code below (note: if the latest kotlin version is greater than > 1.7.20, you need to change 1.7.20 to x.x.x ( x.x.x is the latest Kotlin version ) ).

    buildscript {
    ext.kotlin_version = '1.7.20'
    repositories {
        google()
        mavenCentral()
    }

    dependencies {
        classpath 'com.android.tools.build:gradle:7.2.2'
        classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
    }
}

    Hopefully this help you in some sort of way.
    I have encountered the same exact issue even the GPT failed to help me out, The accepted answer might work for you but it didn’t for me what worked was a set of steps:

    1. Update the Android studio if not already and update suspected dependencies in
      build.gradle(app) after that
      add implementation 'com.android.support:appcompat-v7:26.1.0' if not already
      available .

    2. In project Structure make sure you have compatible (Gradle Plugin version,
      Gradle version and Gradle JDK mine were 7.0.2,7.2 and 11 ).

    3. In Gradle.Properties add
      android.useDeprecatedNdk=true android.enableAapt2=true android.enableUnitTestBinaryResources=false org.gradle.jvmargs=-Xmx2048m -Dfile.encoding=UTF-8

    4. In build.gradle(project)-> allprojects->repositories
      add
      configurations.all { resolutionStrategy.force "com.android.support:support-v4:26.1.0" }

    5. Make sure you have same version of kotlin in both build.gradles e.g:
      classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version" in build.gradle(project)->dependencies
      and implementation "org.jetbrains.kotlin:kotlin-reflect:$kotlin_version" in build.gradle(app) ->dependencies
      where
      ext.kotlin_version = ‘1.8.0’ in build.gradle(project)->buildscript
