DSL element 'android.dataBinding.enabled' is obsolete and has been replaced with 'android.buildFeatures.dataBinding'

Gets following warning when building the project

DSL element 'android.dataBinding.enabled' is obsolete and has been replaced with 'android.buildFeatures.dataBinding'.

I am using Android Studio Canary 6

Starting from Android Gradle Plugin 4.0.0-alpha05 there is a new block called buildFeatures to enable build features.

So in order to enable databinding with new AGP plugin you have do like following in module (ex: app) level gradle file

build.gradle ( Groovy DSL )

// shorter version
// android.buildFeatures.dataBinding true


// longer version

android {

    buildFeatures {

         dataBinding true

         // for view binding:
         // viewBinding true
    }
}

build.gradle.kts ( Kotlin DSL )

// shorter version
// android.buildFeatures.dataBinding = true


// longer version

android {

  buildFeatures {

         dataBinding = true

         // for view binding:
         // viewBinding = true
    }
}

Reference: https://developer.android.com/studio/releases/gradle-plugin#buildFeatures

Put it in build.gradle(app level).It will work with android studio version greater than or equal to 4.0.0.

android {
    buildFeatures{ 
        dataBinding true // for data binding 
        viewBinding true // for view binding
    }
}

This warning occurs because

    dataBinding {
        enabled=true
    }

    viewBinding {
        enabled=true
    }

This code style is deprecated and it will remove from the gradle version 5 now if you still want to use this then you can use androidx legacy support dependencies

in app lavel build.gradle

implementation 'androidx.legacy:legacy-support-v4:1.0.0'

otherwise you can use new code style to enable data binding and view binding

like this

android {

  buildFeatures {

         dataBinding = true

         // for view binding:
         // viewBinding = true
    }
}

> Put this code in Gradle Scripts >> build.gradle(Module: appName.app)

after the buildTypes, include the data biding code

buildTypes {
       release {
           .......
          ........
       }
   }
 //here is the code...
   buildFeatures {
       dataBinding = true
   } 

That's all :)

If you're looking for the new feature viewBinding, try this for Groovy

android {
    ...
    buildFeatures {
        viewBinding true
    }
}

and this for Kotlin

android {
    ...
    buildFeatures {
        viewBinding true
    }
}

But, to use the default android data binding

android {
    ...
    buildFeatures {
        dataBinding true
    }
}

also, be aware to use

kapt "com.android.databinding:compiler:4.0.0"

1- add dataBinding under buildFeatures like this:

android {
...
buildFeatures {
        dataBinding true
    }
...
}

2- Change dagger version to 2.31.2:

annotationProcessor "com.google.dagger:dagger-compiler:$daggerVersion"
implementation "com.google.dagger:dagger:$daggerVersion"

3- Change also butterKnife version to 10.2.3:

implementation 'com.jakewharton:butterknife:10.2.3'
annotationProcessor 'com.jakewharton:butterknife-compiler:10.2.3'

buildFeatures {

        //just for dataBinding ，It has nothing to do with viewBinding 
        dataBinding = true

        //just for viewBinding ，It has nothing to do with dataBinding
        viewBinding = true
    }

Look at the notes above，so it should be very clear

The following works:

android { compileSdkVersion 30 buildToolsVersion "30.0.3"

defaultConfig {
    applicationId "com.poet.navviewmodeljave"
    minSdkVersion 19
    targetSdkVersion 30
    versionCode 1
    versionName "1.0"
    //dataBinding.enabled true
    buildFeatures.dataBinding
    testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
}
