How to Resolve the Error "The Mincompilesdk (31) Specified in a Dependency's Aar Metadata" in Native Java or Kotlin

How can I resolve the error The minCompileSdk (31) specified in a dependency's AAR metadata in native Java or Kotlin?

I have found the solution. Enter this line of code above package in the app Gradle file.

For Kotlin developers:

configurations.all {
    resolutionStrategy { force 'androidx.core:core-ktx:1.6.0' }
}

For Java developers

configurations.all {
    resolutionStrategy { force 'androidx.core:core:1.6.0' }
}

How can I resolve the error The minCompileSdk (31) specified in a dependency's AAR metadata in native Java?

The error message hints at how to resolve the issue. The minCompileSdk can never be higher than your compileSdkVersion which is also hinted in the name of the parameters, as the minCompileSdk is the minimum SDK you want to support, so setting it to a higher value than the compileSdkVersion should intuitively mean that it won't be the minimum sdk version needed.

Either downgrade your minCompileSdk to 30 og upgrade your compileSdkVersion to 31, to fix this issue. You can read more about these parameters in this thread: What is the difference between compileSdkVersion and targetSdkVersion?

minCompileSDK specified in dependency AAR metadata (androidx.window:window:1.0.0-beta04)

replace this code:

android {
    compileSdkVersion 30

    sourceSets {
        main.java.srcDirs += 'src/main/kotlin'
    }

    defaultConfig {
        applicationId "com.example.r_app"
        minSdkVersion 21
        targetSdkVersion 30
        versionCode flutterVersionCode.toInteger()
        versionName flutterVersionName
    }
...........

dependencies {
    implementation platform('com.google.firebase:firebase-bom:28.0.1')
    implementation 'com.google.firebase:firebase-analytics-ktx'
    implementation "org.jetbrains.kotlin:kotlin-stdlib-jdk7:$kotlin_version"
}

by the following

android {
    compileSdkVersion 31

    sourceSets {
        main.java.srcDirs += 'src/main/kotlin'
    }

    defaultConfig {
        applicationId "com.example.r_app"
        minSdkVersion 21
        targetSdkVersion 31
        multiDexEnabled true
        versionCode flutterVersionCode.toInteger()
        versionName flutterVersionName
    }

.......and.......
dependencies {
    implementation platform('com.google.firebase:firebase-bom:28.0.1')
    implementation 'com.google.firebase:firebase-analytics-ktx'
    implementation 'com.google.guava:guava:27.0.1-android'
}

and add the line classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version" in project_file -> android -> build.gradle :

 dependencies {
        classpath 'com.android.tools.build:gradle:4.1.3'
          ......
        classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version" 
    }

After that open for editing in Android Studio on the top right.. Allow it to build. then Run. If required - flutter clean - pub_get in pubspec.yaml. I think this should work.. Because I am not sure what other requirements or errors you are getting.

Android app won't build -- The minCompileSdk (31) specified in a dependency's androidx.work:work-runtime:2.7.0-beta01

The error is being caused because one of your dependencies is internally using WorkManager 2.7.0-beta01 that was released today (which needs API 31). In my case it was CheckAarMetadata.kt.

You can fix it by forcing Gradle to use an older version of Work Manager for the transitive dependency that works with API 30. In your build.gradle file add:

dependencies {
    def work_version = "2.6.0"
    // Force WorkManager 2.6.0 for transitive dependency
    implementation("androidx.work:work-runtime-ktx:$work_version") {
        force = true
    }
}

This should fix it.

The minCompileSdk (31) specified

Add this line of code in-app `build.gradle file.

configurations.all {
        resolutionStrategy { force 'androidx.core:core-ktx:1.6.0' }
    }

One or more issues found when checking AAR metadata values:

Change your compileSdk 30 to 31.

It worked for me!

   compileSdk 31

    defaultConfig {
        applicationId "com.example.lifecycle"
        minSdk 21
        targetSdk 30
        versionCode 1
        versionName "1.0"

        testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
    }
