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
