My project was working perfectly fine until I upgraded my gradle to 4.1 in android studio and all hell broke loose.
I keep getting this error when I clean my project.
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 C:\Users\daviestobialex\AndroidStudioProjects\ShopCentra\app\src\main\res\drawable\trapezoidal_bac.xml : Can't process attribute android:fillColor="@android:color/white": 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.
Apparently, it is throwing an error to a reference call that exists in my color.xml
