API 'variant.getExternalNativeBuildTasks()' is obsolete and has been replaced with 'variant.getExternalNativeBuildProviders()

Question

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WARNING: API 'variant.getExternalNativeBuildTasks()' is obsolete and has been  replaced with 'variant.getExternalNativeBuildProviders()'.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"             }         } 

What exactly do I need to change here?

I have skipped out a few constants and other sensitive information in the app/build.gradle file.

Answer 1

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'    } }

Answer 2

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.
