Flutter: Android dependency 'androidx.core:core' has different version for the compile (1.0.0) and runtime (1.0.1) classpath. You should manually set the same version via DependencyResolution

Okay so I managed to fix the error by adding this snippet of code like so

subprojects {
        project.configurations.all {
            resolutionStrategy.eachDependency { details ->
                if (details.requested.group == 'com.android.support'
                        && !details.requested.name.contains('multidex') ) {
                    details.useVersion "27.1.1"
                }
                if (details.requested.group == 'androidx.core'
                        && !details.requested.name.contains('androidx') ) {
                    details.useVersion "1.0.1"
                }
            }
        }
    }

Paste this into your build.gradle under build script like so.

``` gradle
buildscript {
ext.kotlin_version = '1.2.51'
repositories {
google()
jcenter()
}

dependencies {
    classpath 'com.android.tools.build:gradle:3.2.1'
    classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
    classpath 'com.google.gms:google-services:4.2.0'
}

subprojects {
    project.configurations.all {
        resolutionStrategy.eachDependency { details ->
            if (details.requested.group == 'com.android.support'
                    && !details.requested.name.contains('multidex') ) {
                details.useVersion "27.1.1"
            }

            if (details.requested.group == 'androidx.core'
                    && !details.requested.name.contains('androidx') ) {
                details.useVersion "1.0.1"
            }
        }
    }
}

}

allprojects {
repositories {
google()
jcenter()
}
}

rootProject.buildDir = '../build'
subprojects {
project.buildDir = "${rootProject.buildDir}/${project.name}"
}
subprojects {
project.evaluationDependsOn(':app')
}

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

After upgrading the compileSdkVersion from 27 to 28 on my app, I got this error.

I pasted the following dark magic into .../android/build.gradle (not .../android/app/build.grade) and that made the problem go away:

subprojects {
    project.configurations.all {
    resolutionStrategy.eachDependency { details ->
            if (details.requested.group == 'androidx.core' &&
           !details.requested.name.contains('androidx')) {
        details.useVersion "1.0.1"
            }
    }
    }    
}

I'm having trouble reproducing this so far. If anyone has sharable code that triggers this error it would be really helpful for debugging.

@Atominac found a reproducible case in #27679.

Steps to Reproduce

  flutter_local_notifications:
  firebase_core:
  firebase_messaging:

I use Hixie's function.and the problem go away

No joke, I recently had the same problem (and I was getting many complaints about various dependencies that were AndroidX, with -rc01 version endings), and various solutions for forcing a resolution strategy were not working.

I solved it by upgrading my gradle dependency in the android/build.gradle file: classpath 'com.android.tools.build:gradle:3.3.1' (I was previously on version 3.2.1)

@david-mccoy Thanks ! It worked for me!

@david-mccoy great answer. Annoying androidX issues have been bothering me lately and this worked for me

this worked for me too

No joke, I recently had the same problem (and I was getting many complaints about various dependencies that were AndroidX, with -rc01 version endings), and various solutions for forcing a resolution strategy were not working.

I solved it by upgrading my gradle dependency in the android/build.gradle file: classpath 'com.android.tools.build:gradle:3.3.1' (I was previously on version 3.2.1)

Worked for me after changing also the Kotlin version (I have Kotlin support on my project) to 1.3.0 (I had 1.2.71)

If gradle upgrade from 3.2.1 to 3.3.1, I found a problem that the android:label in androidmanifest.xml will not take effect after modified and meta-data will not take effect. @david-mccoy. Have you found this problem？

Bumping com.android.tools.build:gradle to 3.3.2 solved this issue for me as well.

Since this is a file that was generated by flutter create, is it flutters responsibility to keep it up to date, or me as a developer? 🤔

If you have kotlin support in your flutter app, to solve this problem, you need to change 2 values in android/build.gradle:

1. change kotlin_version from 1.2.71 to 1.3.0

2. change gradle version from 3.2.1 to 3.3.2

happened to me, changing both kotlin and gradle worked

Android dependency 'androidx.core:core' has different version for the compile (1.0.0) and runtime (1.0.2) classpath. You should manually set the same version via DependencyResolution.

[√] Flutter (Channel stable, v1.7.8+hotfix.4, on Microsoft Windows [Version 10.0.17763.678], locale tr-TR)
[√] Android toolchain - develop for Android devices (Android SDK version 29.0.1)

1. Go to android->gradle->wrapper->gradle-wrapper.properties and change the distribution URL to
   distributionUrl=https\://services.gradle.org/distributions/**gradle-5.1.1-all.zip**

#

Upgrade Android Gradle Plugin and Gradle to the latest version can solve this problem. For Android Studio 3.5, modify these:
android/build.gradle

com.android.tools.build:gradle:3.5.0

android/gradle/wrapper/gradle-wrapper.properties

distributionUrl=https\://services.gradle.org/distributions/gradle-5.4.1-all.zip

#

Of course, you should manually set the same version via DependencyResolution. So, the following resolution strategy can also be used to resolve the conflicts of dependency :
android/gradle.properties:

androidxCoreVersion=1.0.0
androidxLifecycleVersion=2.0.0
````
android/build.gradle: 
```groovy
subprojects {
    project.configurations.all {
        resolutionStrategy {
            force "androidx.core:core:${androidxCoreVersion}"
            force "androidx.lifecycle:lifecycle-common:${androidxLifecycleVersion}"
        }
    }
}

the previous error is solved thanks to @Lebogang95 but Im facing a new one with androidx.swiperefreshlayout and androidx.localbroadcastmanager:localbroadcastmanager and it keeps coming every time with a new Error.
One of the Errors reads:
Android dependency 'androidx.drawerlayout:drawerlayout' has different version for the compile (1.0.0-rc01) and runtime (1.0.0) classpath. You should manually set the same version via DependencyResolution

any idea guyz?

Update Gradle solves to me.

distributionUrl=https\://services.gradle.org/distributions/gradle-5.4.1-all.zip

classpath 'com.android.tools.build:gradle:3.5.0'

  }
    }    
}

Thanks for this!!! Been hours trying to figure things out.

I updated the project, migrated to androidx, and upgraded gradle, which I think would be better.

Kotlin Version is V imp for it to work. Do change it to ext.kotlin_version = '1.3.0'

This should be adressed ASAP. Just created a new Flutter project yesterday and I had to fix this issue from like 1 year ago today:
Change Kotlin to:
ext.kotlin_version = '1.3.0'
and Gradle to:
classpath 'com.android.tools.build:gradle:3.3.1'

If this is the support that Google tries to sell, I am not seeing it. Inacceptable for a Framework that wants to gain traction...

I solved it by upgrading my gradle dependency in the android/build.gradle file: classpath 'com.android.tools.build:gradle:3.3.1' (I was previously on version 3.2.1)

I had just migrated to AndroidX and was in the process of implementing firebase_core and firebase_messaging, when I came across this error. Migrating to Gradle 3.3.1 as @david-mccoy mentioned fixed the issue for me. Thanks!

this is very bad, very annoying, every time i start a new project with Flutter i have to edit several files from android folder for the compile project, like "gradle.properties" adding the lines

android.useAndroidX = true
android.enableJetifier = true

edit the file "android / build.gradle"

Set Gradle to 3.3.1 instead of 3.2.1
Add dependency com.google.gms: google-services: 4.3.2
Set kotlin version to 1.3.0 ext.kotlin_version = '1.3.0'

edit android / app / build.gradle

add Firebase SDK
implementation 'com.google.firebase: firebase-analytics: 17.2.0'

add SDKs to any other Firebase product
https://firebase.google.com/docs/android/setup#available-libraries

add at end of file
apply plugin: 'com.google.gms.google-services'

add dependency
implementation 'com.android.support:multidex:1.0.3'

This is all very bad, it seems that Flutter is a smarter and unprofessional thing.

No need to change dependencies versions manually. Just open project with Android Studio and Refactor -> Migrate to AndroidX... and everything will work as expected.
Reference: https://flutter.dev/docs/development/androidx-migration

@theshyelf
Ideally, if you didn't have to do any of this.
Ideally, from the moment I added the package to pubspec, this would be done automatically. Similar to Nuget Xamarin packages in visual Studio

after this I had to execute a flutter pub cache repair to make it build again

as at 2019/03/28.

Thank you. This one solve my problem today.

My solution is as follows:

1. Change to 3.3.1 in build.grade in the project root directory, and then delete ext.kotlin_version = '1.3.31'
2. Add it again under grade. Properties,
   Android. UseAndroidX = true
   Android. EnableJetifier = true,
   Save the first line org.gradle.jvmargs= -xmx1536m
   Delete the rest.
3. The last sync

我的解决方案如下:
1.先在项目根目录下的build.grade中,改为3.3.1.然后删除ext.kotlin_version = '1.3.31'
2.再在grade.properties下添加,
android.useAndroidX = true
android.enableJetifier = true,
保留第一行 org.gradle.jvmargs=-Xmx1536M
其余删除.
3.最后 sync

I dont want to migrate to androidx as it doesnt support lower versions of android what to do?

I'm having trouble reproducing this so far. If anyone has sharable code that triggers this error it would be really helpful for debugging.

Easy to reproduce:

1. create a new flutter project AndroidStudio
2. add cloud_firestore: ^0.11.0+1 to pubspec.yaml
   observe compilation errors
   Execution failed for task ':app:preDebugBuild'.

Android dependency 'android.arch.lifecycle:runtime' has different version for the compile (1.0.0) and runtime (1.1.1) classpath. You should manually set the same version via DependencyResolution

• Try:
  Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output. Run with --scan to get full insights.
• comment #cloud_firestore: ^0.11.0+1
• execute run, observe apk is successfully generated.

  Hope this helps!
  Thank you for helping with this error!

@override

Thanks so much. Worked for me

No need to change dependencies versions manually. Just open project with Android Studio and Refactor -> Migrate to AndroidX... and everything will work as expected.
Reference: https://flutter.dev/docs/development/androidx-migration

It will just say you that no use of AndroidX in current project. That's it, you have to make manual changes.

My solution is as follows:

1. Change kotlin_version from 1.2.71 to 1.3.0
2. Change gradle version from 3.2.1 to 3.3.1

had to have a flutter command to check and fix the project automatically.

I've made the updates but still get the same error:

the error indicates that Kotlin version was not updated.

This is happening when using image_picker: ^0.6.2+3 . with cloud_firestore: ^0.13.0+1

Same as @bdairy , just added _image_picker_ and I have the problem:
cloud_firestore: ^0.13.0+1
firebase_storage: ^3.1.1
image_picker: ^0.6.3

Solved with:

buildscript {
    ext.kotlin_version = '1.3.0'
    repositories {
        google()
        jcenter()
    }

    dependencies {
        classpath 'com.android.tools.build:gradle:3.3.2'
        classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
        classpath 'com.google.gms:google-services:4.3.2'
    }
}

The issue is that the project is likely using an older version of Gradle, Android Gradle plugin and Kotlin.

If you still see this issue, ensure:

1. <app-dir>/android/build.gradle contains this section:

```.groovy
buildscript {
ext.kotlin_version = '1.3.50'
repositories {
google()
jcenter()
}

dependencies {
    classpath 'com.android.tools.build:gradle:3.5.0'
    classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
}

}

2. `<app-dir>/android/gradle/wrapper/gradle-wrapper.properties` contains this code:
```.properties
distributionBase=GRADLE_USER_HOME
distributionPath=wrapper/dists
zipStoreBase=GRADLE_USER_HOME
zipStorePath=wrapper/dists
distributionUrl=https\://services.gradle.org/distributions/gradle-5.6.2-all.zip

1. Ensure the app is migrated to AndroidX:
   .properties org.gradle.jvmargs=-Xmx1536M android.enableR8=true android.useAndroidX=true android.enableJetifier=true

cc @zanderso this is another instance of files getting out of sync. We don't see these issues in the devicelab because we only test against a single combination of these dependencies.

@blasten thanks for the reply,, But really all these settings are exactly the same,, yet I am still getting the same error. I even run flutter clean.. check the screen shots and flutter doctor. This stopping my work I would really appreciate your help guys.. thanks

Setting up firebase:

Use gms service version as shown in the code below in app.gradle instead of 4.3.2 or any other version :

classpath 'com.google.gms:google-services:4.2.0'

Add this snippet to build.gradle below dependencies:

subprojects {
        project.configurations.all {
            resolutionStrategy.eachDependency { details ->
                if (details.requested.group == 'com.android.support'
                        && !details.requested.name.contains('multidex') ) {
                    details.useVersion "27.1.1"
                }
                if (details.requested.group == 'androidx.core'
                        && !details.requested.name.contains('androidx') ) {
                    details.useVersion "1.0.1"
                }
            }
        }
    }

Change dependenicie in build.gradle (outside of app->build.gradle)
classpath 'com.android.tools.build:gradle:3.3.1'
note that initially its 3.2.1 or can be some other version too.

change kotlin version to 1.3.0 from 1.2.71 or something else

goto gradle.properties and paste this snippet of code:

android.useAndroidX = true
android.enableJetifier = true

Hi @bdairy

I was having the same issue.
Please ensure the following things. I still see in your updated version statement:

classpath 'com.android.tools.build:gradle:3.5.0'
which should be 3.3.1

Also have you set minimum sdk version to 21?
Further I hope you have added this set of lines in gradle.properties:

android.useAndroidX = true
android.enableJetifier = true
```
Also you have changed kotlin version to 1.3.50 but it should be 1.3.0

@sedhha my friend,, All what you've mentioned caused the same problem,,

the main issue is that Kotlin version update is not affecting the build...
as you can see my kotlin version is set to ext.kotlin_version = '1.3.0' . but the error says it is org.jetbrains.kotlin:kotlin-gradle-plugin:1.2.71

Now if any one has a solution for that please help I am really Stuck without any clarification of the issue...

@blasten any update on this issue>? is there any hot fix? anything . I can do,, it has been more than 6 days,, please guys

Just for the reference the problem was with a plugin that is called flutter_launch.. which no one notice in the error including me because the package name also miss leading,, anyway... I had to go the plugin and update the Kotlin version over there to fix the issue,, Thanks for the help everybody.

@bdairy sorry for not replying earlier. The problem is in the flutter_launch plugin https://pub.dev/packages/flutter_launch. Which version of this plugin are you using? I saw the version was updated in Jun 2019: https://github.com/thyagoluciano/flutter_launch_whatsapp/commit/d29f6359d339286519d682fb19dc4b48d3de0625

@csells How will this be handled in future? I ran today into this after upgrading flutter and my plugins. At least we should find better error messages that tells the user what to do OR even better make flutter doctor to be able to fix such things

The resolution of this problem involves finding plugin versions that satisfy the version constraints of each supported platform. When pub resolves a dependency, it doesn’t have knowledge of platform dependencies such as the Kotlin version used in a plugin.

That said, error messages can be improved.

We can highlight the specific plugin that is having issues. Currently, you get a Gradle error, which refers to a plugin as project.

hello guy 1 actually have a problem "sync project with gradles file". it's disabled and how can i enable and show it in the android menu

?

follow these steps
step #1
$ flutter clean
$ flutter pub cache repair

step #2
in appRoot -> android -> build.gradle

• set ext.kotlin_version = '1.3.50' or later versions
• in dependencies set gradle version to 3.6.1 or later version
  classpath 'com.android.tools.build:gradle:3.6.1'
• in subprojects add
  project.configurations.all {
  resolutionStrategy.eachDependency { details ->
  if (details.requested.group == 'androidx.core' &&
  !details.requested.name.contains('androidx')) {
  details.useVersion "1.0.1"
  }
  }
  }

step #3
in adnroid -> gradle -> wrapper -> gradle-wrapper.properties
set gradle to gradle-5.6.4-all.zip or later versions
distributionUrl=https\://services.gradle.org/distributions/gradle-5.6.4-all.zip

step #4
$flutter clean

step #5
$flutter run

I'm closing this bug as the original issue was caused by combining AndroidX and support dependencies. The AndroidX migration guide walks through the steps to avoid this problem: https://flutter.dev/docs/development/androidx-migration.

If you have kotlin support in your flutter app, to solve this problem, you need to change 2 values in android/build.gradle:

1. change kotlin_version from 1.2.71 to 1.3.0
2. change gradle version from 3.2.1 to 3.3.2

as at 2019/03/28.

thanks，for this ,it works for me

I pasted the following dark magic into .../android/build.gradle (not .../android/app/build.grade) and that made the problem go away:

subprojects {
    project.configurations.all {
  resolutionStrategy.eachDependency { details ->
            if (details.requested.group == 'androidx.core' &&
         !details.requested.name.contains('androidx')) {
      details.useVersion "1.0.1"
            }
  }
    }    
}

works for me perfectly

One of the Best Github Issue Discussion I have ever seen

https://github.com/flutter/flutter/issues/27254#issuecomment-461692152
solved my isssue

Running into this issue again after updating cloud_firestore from 0.13.5 to 0.14.0+2.

Worked for me as well.

This is what it looks like in the build.gradle file:

buildscript {
    ext.kotlin_version = '1.3.0'
    repositories {
        google()
        jcenter()
    }

    dependencies {
        classpath 'com.android.tools.build:gradle:3.3.2'
        classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
    }
}

Is there a way to let flutter do this change when a package that relies on it is being updated/added?

Still does not work after all the suggestions

No joke, I recently had the same problem (and I was getting many complaints about various dependencies that were AndroidX, with -rc01 version endings), and various solutions for forcing a resolution strategy were not working.

I solved it by upgrading my gradle dependency in the android/build.gradle file: classpath 'com.android.tools.build:gradle:3.3.1' (I was previously on version 3.2.1)

Thanks！ It worked for me!
