Updated Android Studio to 3.0 and getting this issue

Question

Error:Execution failed for task ':App:mergeDebugResources'.
    > There were multiple failures while executing work items
       > A failure occurred while executing com.android.build.gradle.tasks.MergeResources$FileGenerationWorkAction
          > Error while processing /media/nikhilesh/App/src/main/res/drawable/ic_add_black_24dp.xml : Can't process attribute android:fillColor="@color/green": references to other resources are not supported by build-time PNG generation. See http://developer.android.com/tools/help/vector-asset-studio.html for details.

How can we solve this?

Answer 1

You can add the following line inside your default config of your app build.gradle:

defaultConfig{
   vectorDrawables.useSupportLibrary = true
}

Edit: you also need to add this dependency if you didn't already

dependencies {
    compile 'com.android.support:appcompat-v7:27.1.1'
}

Update:

Since Gradle 3.4 the compile configuration is deprecated and should be replaced by implementation:

dependencies {
    implementation 'com.android.support:appcompat-v7:27.1.1'
}

Answer 2

The problem is because the new gradle cannot refer to color library, which you use to get the @color/green value.

The solution is same as rotemitz said Just add this line to your defaultConfig of build.gradle (Module : app)

vectorDrawables.useSupportLibrary = true

AND to dependencies of the same build.gradle

compile 'com.android.support:appcompat-v7:23.1.0'

Note : You may change the appcompat version, refer to your compile SDK version

Answer 3

You just need to add the following line inside your default config of your app build.gradle:

defaultConfig{
       vectorDrawables.useSupportLibrary = true
    }
