Using Android Studio 3.3 Canary 11 with the gradle plugin version 3.3.0-alpha11. It throws the following error when trying to sync gradle 

WARNING: API 'variant.getExternalNativeBuildTasks()' is obsolete and has been 
replaced with 'variant.getExternalNativeBuildProviders()'.
It will be removed at the end of 2019.
For more information, see https://d.android.com/r/tools/task-configuration- 
avoidance
Affected Modules: app

Clicking on the error leads me to this line in the gradle file 

applicationVariants.all { variant ->
            variant.outputs.all {
                outputFileName = "${variant.name}-${variant.versionName}.apk"
            }

The issue has been fixed in their latest release 'io.fabric.tools:gradle:1.30.0'

Please update your both gradle fabric tools with 1.30.0

buildscript {
  // ... repositories, etc. ...

   dependencies {
       // ...other dependencies ...
       classpath 'io.fabric.tools:gradle:1.30.0'
   }
}

  • I'm still getting this warning with `classpath 'io.fabric.tools:gradle:1.31.0'` and `implementation 'com.crashlytics.sdk.android:crashlytics:2.10.1'`. It's either broken again or not fixed for all cases. – Gene S Aug 02 '19 at 06:41

EDIT

This issue has been fixed in Fabric 1.28.0. In your build.gradle of the project level, add the following line:

classpath 'io.fabric.tools:gradle:1.28.1'

Previous Answer

It happens after I updated Android Studio to 3.3.0. apply plugin: 'io.fabric' is the cause. I have sent a bug report to Firebase team about this issue.

You have 3 options:

  • Wait until the next version of Fabric plugin is released. Check the latest version here.

  • Downgrade to Android Studio 3.2.1.

  • Comment out io.fabric plugin.

In build.gradle of your app's module:

apply plugin: 'com.android.application'
// apply plugin: 'io.fabric' <== this plugin causes the error

However, you can still build and run your projects even though this error appears. Just ignore it.

    Would it be possible for you to link to the bug report or issue you opened with Firebase? I'd love to upvote it. – yuval Jan 15 '19 at 00:00

    I have to use the `io.fabric` plugin then how can i remove this warning without changing this? – 0xAliHn Jan 16 '19 at 13:57
  • And Also disable the dependency of Crashlytics. – Infinite Loops Jan 17 '19 at 03:34

    This is the cause, not a viable solution – Daniel Wilson Jan 17 '19 at 08:45

    They are saying that you can use it until end of the 2019 year. For now I'm using, we will see what happens ) – Shuhrat Akramov Jan 21 '19 at 01:29
  • 1
    @DarshanMiskin this is normal, either remove completely crashlytics or keep the warning for now. If your app is not building at all you can check comments below for solution – 113408 Jan 23 '19 at 21:15
  • This definitely seems to be the cause, wouldn't migrating to Firebase crashlytics solve this, since Fabric is integrating it's features in to Firebase, i'm following this guide: https://proandroiddev.com/migrating-crashlytics-to-the-firebase-console-5e05b6ff8c12 – JimmyFlash Jan 24 '19 at 12:05

    Why downgrading? No sense! It's just a warning, it's not removed yet and it can build your project (the whole 2019 year...). I believe they will fix it during this year – user25 Jan 25 '19 at 10:33
  • I agree for just a warning downgrading seems too extreme. If its a platform change the (google) will most probably make it explicit for instance that we should move from fabric to firebase crashlystics type-configuration – samuel owino Feb 04 '19 at 11:16

    For now the best thing to do is to live with the warning. Maybe they'll fix it in the near future – Tamoxin Feb 08 '19 at 18:41
  • `io.fabric.tools:gradle:1.27.1` is still having this issue. – Kimi Chiu Mar 02 '19 at 02:31
  • I got .this error after removing this. The Crashlytics build ID is missing. This occurs when Crashlytics tooling is absent from your app's build configuration – Vishal Patoliya ツ Mar 12 '19 at 10:14
  • https://docs.fabric.io/android/changelog.html#fabric-gradle-plugin and https://fabric.io/kits/android/crashlytics/install have the latest versions. – Andrew Koster May 28 '19 at 17:34

in application build.gradle , downgrade to this stable version of gradle :

classpath 'com.android.tools.build:gradle:3.2.1'

It happens after I updated Android Studio to 3.3 , temp solution until they fix it !

edit: you don't need to downgrade your android studio !

    Then you also have to downgrade to Android Studio 3.2.1. Thanks anyway – Rubén Viguera Jan 15 '19 at 11:15

    It worked without downgrading anything thanks for the suggestion – Sid Jan 15 '19 at 19:28
  • I had the same problem after upgrading Android Studio (AS) to version 3.3. I got Gradle sync to work again by downgrading Gradle to version 4.6 and Android Gradle Plugin to version 3.2.1, which was the versions I was using prior to the AS update. Look up the table [here](https://developer.android.com/studio/releases/gradle-plugin) if you are doubt how to modify the versions for gradle and the plugin. – Rabie Jradi Jan 15 '19 at 12:57
  • Since my answer was converted into the comment you see above let me add that I couldn't get the proposed solution of this answer to work by only changing the version of the gradle plugin to 3.2.1. I had to also downgrade gradle to 4.6, otherwise gradle sync would still complain. – Rabie Jradi Jan 17 '19 at 12:38

    you don't need to downgrade your android studio @RubénViguera – Amer AlZibak Jan 23 '19 at 21:02

    You don't need to downgrade anything other than gradle version as mentioned in the answer. This should be the accepted answer. – Danish Ansari Feb 23 '19 at 07:14

UPDATE As of today you can use classpath 'io.fabric.tools:gradle:1.28.0' to fix this issue !

If commenting out Crashlytics's plugin io.fabric on the app gradle file worked for you temporarily 

//apply plugin: 'io.fabric'

Then upgrading your fabric gradle dependencies on the Project gradle file will permanently solve the issue:

classpath 'io.fabric.tools:gradle:1.27.0'

NB: this doesn’t remove the warnings but let you use Crashlytics with AS3.3+

  • @RJB Are you using Crashlytics? If you remove it from your project it works ? If yes then this should fix the issue. However you might still get warnings, but the project will compila and you can generate your apk safely – 113408 Jan 18 '19 at 07:50
  • Yes. I mean that I am still getting the warning. – RJB Jan 18 '19 at 07:55
  • the op and others (including me) had this issue and were unable to compile the project with `crashlytics` enabled. So to keep Crashlytics and still push to prod you can use the above mentioned update even though it still trigger "warnings". – 113408 Jan 18 '19 at 15:20

Not sure what the actual issue is but commenting out the crashlytics related dependencies from the project solved issue.

It's confirmed as bug for Crashlytics and they are working on it.

https://issuetracker.google.com/issues/116408637

Quoted from Google assignee:

je...@google.com #23 Jan 23, 2019 01:40AM
Hi all,

Thank you for your patience.

It looks like the bug in all cases is coming from crashlytics and I've filed a bug with them.

I will keep you updated on the status.

For me, my debug app is working fine on my device just by running and ignoring the warning without commenting Crashlytics or Fabric. I have not try for production.

Update:

Google Issue Tracker had mark this issues as Won't Fix (Infeasible) because all the issues was from Crashlytics, and let fixes done by Crashlytics team (despite they are same Googler...).

They suggest to follow this link for Crashlytics updates:

https://github.com/firebase/firebase-android-sdk/issues/198

Note: I'm still using Android Studio 3.3 with io.fabric.tools:gradle:1.26.0 without commenting any of Craslytics and it's works fine on my debug app.

Update:

I can confirm now that it works fine on my production/release version app. How do I know it works? Because it had sent me back a crash reports -_-'

Anyway, just ignore the warning, they should fix it eventually.

Aww, just read that it had fixed with fabric 1.28.0 :)

Latest news from 01/24/2019

enter image description here

Info here https://issuetracker.google.com/issues/116408637

We will need to wait untill Crashlytics came up with a solution, here is GitHub issue opened

https://github.com/firebase/firebase-android-sdk/issues/198

The only way I'm using as right now to not comment io.fabric plugin is downgrading my gradle and upgrading my fabric classpath (this is working on my production app)

 dependencies {
        classpath 'com.android.tools.build:gradle:3.2.1'
        classpath 'com.google.gms:google-services:4.2.0'
        classpath 'io.fabric.tools:gradle:1.27.0'

        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }

As it was said, the problem is with Fabric/Crashlytics.

apply plugin: 'io.fabric'

It's a bug on Crashlytics/Firebase side, please check the following link and see the bug' status : https://github.com/firebase/firebase-android-sdk/issues/198

the issue-tracker might refer to "lazy task configuration" -

that's at least what task configuration avoidance suggests.

but one possibly can prevent the access to this obsolete method of BaseVariantImpl, when variant.outputs.all won't access that method (internally) - or when checks can prevent the access; or when accessing the variant by it's name; or somehow disable the external native build tasks for the variant. also see the single-variant project sync option, which rather seems related.

or wait for build-tools 3.3.0-alpha12 or 3.3.0-beta1 ...this is not even a release candidate, therefore investing to much time might be pointless - except using it to file another bug-report.

the new quick feedback quick feedback button still looks the most promising.

For me, I followed these steps: 1. upgrade the Gradle dependency on project level build.gradle.

        classpath 'io.fabric.tools:gradle:1.28.0'

  1. add this plugin dependency below apply plugin: 'com.android.application' in the app level build.gradle.

        apply plugin: 'io.fabric'

  2. Sync the project with gradle files.

This happens due to the update of your Android Studio from Android Studio 3.2.0 to Android Studio 3.3.0. Update Your Gradle Dependencies (Project)of IO.Fabric. Like:

classpath 'io.fabric.tools:gradle:1.27.1'

and also update your Kotlin version to

classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:1.3.20"

This will resolve this issues. Thanks

this has been fixed in the latest release of the Fabric gradle plugin, 1.28.0, which went live today. Have this in your top-level build.gradle:

buildscript {
// ... repositories, etc. ...

dependencies {
    // ...other dependencies ...
    **classpath 'io.fabric.tools:gradle:1.28.0'**
}

Build log prints how to debug this, particularly you need to run build with -Pandroid.debug.obsoleteApi=true, that'll print stack-trace of call to deprecated API and you'll be able to figure which plugin/code calls it.

If it ends up being your code — use new Provider API (read Lazy Task Configuration doc)

If it comes from other plugin — report to them with stack-trace and warning message and maybe submit a patch. As in this case its related to io.fabric issue.

Changing source compatibility in module build.gradle file to Java 8 fixes the issue

compileOptions {
    sourceCompatibility 1.8
    targetCompatibility 1.8
}

Be sure to rebuild the project after adding those lines

In my case, I needed to use io.fabric plugin, and the solution was, to update to the latest fabric tools gradle version:

classpath 'com.android.tools.build:gradle:3.3.0'
classpath 'io.fabric.tools:gradle:1.27.0'

For those who need to keep the Fabric plugin applied, the temporary solution is to go back to the previous version of the gradle at the project level.

Change the classpath version to com.android.tools.build:gradle:3.2.1.

It was a problem with latest gradle (in my case 3.3.2) version and Fabric.io plugin. It is now solved by the new version Users should have this in their top-level build.gradle:

buildscript {
   // ... repositories, etc. ...

    dependencies {
        // ...other dependencies ...
        classpath 'io.fabric.tools:gradle:1.28.0'
    }
}

Fix is update the root build gradle files to latest. And this answer hold true now. in fureture again new change will be implementing by gradle and android SDK. At times answer will vary in due course of time.

repositories {
    maven { url "https://jitpack.io" }
    maven {
        url 'https://maven.fabric.io/public'
    }
    google()
    jcenter()

}
dependencies {

    classpath 'com.android.tools.build:gradle:3.5.0'
    classpath 'com.google.gms:google-services:4.3.0'
    classpath 'io.fabric.tools:gradle:1.30.0'
}
