解决错误java.lang.UnsupportedOperationException

遇到错误

 Error:Execution failed for task ':app:transformClassesWithDexForDebug'.

> com.Android.build.api.transform.TransformException: com.android.ide.common.process.ProcessException: Java.util.concurrent.ExecutionException: java.lang.UnsupportedOperationException 

导致编译失败，加入一行代码就可以了。
