Issues were found when checking AAR metadata: androidx.core:core:1.12.0-alpha01 and androidx.core:core-ktx:1.12.0-alpha01

I am working on a project and today the build is not working anymore.
The error is the following:

From my research, I understand that the version from the error message were released yesterday, according to the official documentation.

Below are the build.gradle scripts that the project is using.
In my build.gradle I have implementation 'androidx.core:core-ktx:1.9.0'. I don't understand why another version is added at the build phase and also why androidx.core:core:1.12.0-alpha01 is added.

build.gradle:

I had the same error today, and this is what fixed it for me: check in all your library modules for this import in the build.gradle files (you can search in Android Studio in the Edit → Find → Find in Files... menu option):

implementation 'androidx.core:core-ktx:+'

Replace it with the latest stable version to avoid the error:

implementation 'androidx.core:core-ktx:1.9.0'

Synchronise your project and the errors should be gone!

I have the same problem. Add this line; it's related to Android 14 changes:

defaultConfig {
compileSdkPreview = "UpsideDownCake"
}

I had the same problem, but my project didn't have this generic dependency:

androidx.core:core-ktx:+

But some of my dependencies had it (you can see it with the Gradle "Dependency analyser"). So you need to tell Gradle to force a specific dependency version for your dependencies:

configurations.all {
resolutionStrategy {
force("androidx.core:core-ktx:1.9.0")
}
}

Go through your dependencies and make sure to specify explicitly the exact version you'd be using, I had this issue and it is a multi-module project I used 1.9.0 in some modules and in some modules I used core-ktx:+.

just change

implementation("androidx.core:core-ktx:+")

to

implementation("androidx.core:core-ktx:1.9.0")

or a later stable version

I had the same problem.

This helped:

defaultConfig {
compileSdkPreview = "UpsideDownCake"
}

But it created a problem at the moment of creating the APK file/bundle, so the best solution for me was to downgrade Gradle.

Android Gradle Plugin Version 7.1.1 || Gradle Version 7.3

Here's what worked for me :

Project Structure > Dependencies > app > core-ktx+ > Requested Version

Change it to "1.9.0"

Apply.

androidx.core:core: is either a dependency declared in your module's build.gradle or pulled in as a transitive dependency into your project. There's a good chance that it is declared as androidx.core:core-ktx:+ which will make Gradle pull in the latest version of your dependency.

This is something Gradle will warn you against with the message:
> Avoid using + in version numbers; can lead to unpredictable and unrepeatable builds'.

Finding the dependency and giving it a specific version instead of + should fix the issue.

Like Aleksandr Zurnachyan said.
I face the same problem.

Recommended action: Use a different version of dependency 'androidx.core:core:1.12.0-alpha01', or set compileSdkPreview to "UpsideDownCake" in your build.gradle file if you intend to experiment with that preview SDK.

I have found another way to fix this issue.
We can't force update all project dependencies to androidx.core:core-ktx:1.9.0, because I have used many libraries which uses older version of this library.

A solution that worked for me

Downgrading Gradle version from 7.4 to 7.3 worked for me.

My Android Studio version: version 15 (Dolphin), 2021.3.1 Patch 1

My New

Android Gradle Plugin Version 7.1.1
|| Gradle Version 7.3

First, add these dependencies to your build.gradle(Module) file and sync.

implementation("androidx.core:core-ktx:$core_version")
implementation("androidx.core:core-role:1.0.0")

I think your problem will be solved...

Downgrading from googlePlayServicesLocationVersion = "20.0.0" to "19.0.0" helped.
