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.

我们怎么解决这个问题？

Answer 1

您可以在app build.gradle的默认配置中添加以下行:

defaultConfig{
   vectorDrawables.useSupportLibrary = true
}

编辑:如果您还没有,还需要添加此依赖项

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

更新:

从Gradle 3.4开始,compile配置已弃用,应替换为implementation:

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

Answer 2

问题是因为新的gradle无法引用用于获取@ color/green值的颜色库.

解决方案与rotemitz相同,只需将此行添加到build.gradle的defaultConfig(模块:app)

vectorDrawables.useSupportLibrary = true

和相同build.gradle的依赖项

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

注意:您可以更改appcompat版本,请参阅您的编译SDK版本

Answer 3

您只需要在app build.gradle的默认配置中添加以下行:

defaultConfig{
       vectorDrawables.useSupportLibrary = true
    }
