I have seen your build.gradle file and you are using ext.kotlin_version = '1.9.0' which is not widely supported yet.
could please downgrade to 1.8.0 at least

this is my build.gradle file:
buildscript {
ext.kotlin_version = '1.8.0'
repositories {
google()
mavenCentral()
}

dependencies {
    classpath 'com.android.tools.build:gradle:7.4.2'

}

}

[jgarciamccausland]

Any updates or workarounds?

[kgadva]

For me it worked to update the Kotlin version in the build.gradle file to 1.9.0
ext.kotlin_version = '1.9.0'

[jgarciamccausland]

Yep, that worked in our environment as well. Thanks!

[hatch01]

It work, but many other packages are incompatible with this Kotlin version, so I can't use it in my project.
And I get some warning using it :

save my day, thanks

[thamaraSenanayake]

try to update the minSdkVersion

[vbuberen]

It seems to me that the issue is in fact that to use Kotlin 1.9.x project needs to already be on Android Gradle Plugin 8. I have already discovered it in Plus Plugins and this is the reason why I am reverting Kotlin version back to 1.7.22 till AGP 8 is more adopted among Flutter projects.

Error comes from R8 in AGP older than 8.x not supporting Kotlin 1.9.x as it can be seen here: https://developer.android.com/build/kotlin-support

[juliansteenbakker]

Hi all, i'm testing if downgrading the version won't break anything. If not, then ill release a new version with downgraded kotlin version.

[KolyaParadiuk]

Hi! I had the same problem, but managed to run app.
I added jcenter() in android/build.gradle in allprojects

allprojects {
    repositories {
        google()
        mavenCentral()
        jcenter()

    }
}

use ext.kotlin_version = '1.9.0'
and classpath 'com.android.tools.build:gradle:7.2.2'

with this configuration app runs without errors

[donjordano]

the only thing that worked for me was adding this to app/build.gradle

configurations.all { resolutionStrategy { eachDependency { if ((requested.group == "org.jetbrains.kotlin") && (requested.name.startsWith("kotlin-stdlib"))) { useVersion("1.7.10") } } } }

[navaronbracke]

@mhd-ghaith-abtah Are you still having this issue when using version 3.5.1? We recently did a downgrade to Kotlin 1.7.x due to an issue with Kotlin 1.9.x

[thiagosoaress2]

Hi! I had the same problem, but managed to run app. I added jcenter() in android/build.gradle in allprojects

allprojects {
    repositories {
        google()
        mavenCentral()
        jcenter()

    }
}

use ext.kotlin_version = '1.9.0' and classpath 'com.android.tools.build:gradle:7.2.2'

with this configuration app runs without errors

This worked for me. I was previosloy using classpath 'com.android.tools.build:gradle:7.4.2'

[navaronbracke]

@thiagosoaress2 I advise not using jcenter, as is was sunset a while ago: https://jfrog.com/blog/into-the-sunset-bintray-jcenter-gocenter-and-chartcenter/

Is there a specific reason why you need Kotlin version 1.9.0 ? The plugin was downgraded back to Kotlin 1.7.x due to complaints from other users.

There shouldn't be an issue with the com.android.tools.build:gradle version. The plugin itself is using Gradle 8 even, which works fine on the example app.

[Jacqqq]

After long fight with gradle,
eventually ended up with setup

kotlin 1.8.0
classpath 'com.android.tools.build:gradle:7.2.2'
classpath 'com.google.gms:google-services:4.3.15' !

[IwanPWK]

delete folder .gradle, go to inside build, delete all folders, or just delete folder build, then setup like this
kotlin 1.8.0, 1.9.0 whatever
classpath 'com.android.tools.build:gradle:7.2.2'
classpath 'com.google.gms:google-services:4.3.15'

just in case (optional)
maybe you have to set up
Future main() async {
WidgetsFlutterBinding.ensureInitialized();
await Firebase.initializeApp();
runApp(const MyApp());

[alexandrim0]

deleting of .grade and build solve problem even with kotlin 1.9.0 and gradle 8.1.0

please help

[navaronbracke]

The mobile_scanner example application runs fine with Kotlin 1.9.x, however, your combination of dependencies might not be compatible with Kotlin 1.9.x

Does it work if you switch to Kotlin 1.8.x ?

[LuqmaanMohammed]

No it doesn't work

[navaronbracke]

We are going to need the full gradle build log to see what the actual issue is. Could you open the native Android project and run a Gradle build with the --stacktrace and --info options? (--stacktrace and --debug might help too)

I also noticed, you are running Gradle 8, with Java 8. Could you ty to upgrade Java to Java 17? (see the example app for the Java 17 configuration)

The service com.android.tools.idea.explainer.IssueExplainer seems to be IntelliJ related?

Could you run Gradle directly, through Android Studio?

[LuqmaanMohammed]

Sir could you please run the repo on your pc and check it i am will be very grateful to you please i am a beginner so am not able to understand the errors and what to do please could you check it and see

[navaronbracke]

I will have a look at the Gradle error with the mobile_scanner example app.

[endruuu]

Might not be a good idea to everyone, but try to increase the minSdkVersion to 24 - that's all.
No need to change the gradle or kotlin version.

[Crucialjun]

Might not be a good idea to everyone, but try to increase the minSdkVersion to 24 - that's all. No need to change the gradle or kotlin version.

This worked for me

[ps9310]

This worked for me

me too!

[KallewMachado]

Pode não ser uma boa ideia para todos, mas tente aumentar minSdkVersionpara 24 – isso é tudo. Não há necessidade de alterar a versão Gradle ou Kotlin.

This worked for me too

[ziqq]

This case work for me

minSdkVersion 23

plugins {
  id "dev.flutter.flutter-plugin-loader" version "1.0.0"
  id "com.android.application" version "7.2.2" apply false
  id "org.jetbrains.kotlin.android" version "1.9.22" apply false
  id "com.google.gms.google-services" version "4.3.15" apply false
}

[saty-a]

Might not be a good idea to everyone, but try to increase the minSdkVersion to 24 - that's all. No need to change the gradle or kotlin version.

Just updating the minSdkVersion from 21 to 23 worked for me. Thanks @endruuu.

[MrCyjaneK]

@saty-a's suggestion is great but in my case it increased app size by 3x (from 90mb to 280mb) which is somewhat unacceptable, but it did compile and run without problems.

[yelyseiruban]

inside android/build.gradle

buildscript {
ext.kotlin_version = '1.9.22'
repositories {
google()
mavenCentral()
}

dependencies {
    classpath 'com.android.tools.build:gradle:7.2.2'
    // START: FlutterFire Configuration
    classpath 'com.google.gms:google-services:4.3.15'
    // END: FlutterFire Configuration
    classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
}

}

worked for me

[navaronbracke]

Since this issue seems to be resolved by updating the min SDK and or Kotlin version of the Android project, I'm going to close this issue.

[aymendn]

I had a similar problem with Flutter 3.19 and solved it with these versions:

• android/build.gradle

buildscript {
    ext.kotlin_version = '1.9.0' // upgraded to kotlin 1.9
    repositories {
        google()
        mavenCentral()
        jcenter() // added this
    }

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

In case someone else runs into this issue, don't bump the minSdk to 24. That's likely wrong. Odds are you are running into this because you create a project prior to flutter 3.16. If thats the case, you need to update your build.gradle files using the new declerative plugins {} block. This must be updated manually. The link steps you through the process for the updates. Additionally, you will need to update AGP to at least 8.0+. That part I am not too confident in, but it's what was needed for my build to pass without changing the minSdk version.

Updating minSDK to 24 works for me but I am wondering what changed between 23 and 24 that fixes this issue?
