Android Studio中references to other resources are not supported by build-time PNG generation解决方案

问题

Can't process attribute android:strokeColor="@color/ucrop_color_toolbar_widget": 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.

解决方案

参考文档：http://developer.android.com/tools/help/vector-asset-studio.html

在项目build.gradle中，添加如下代码：

android {
  defaultConfig {
    vectorDrawables.useSupportLibrary = true
  }
}

OK，完美解决~
