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

android / app / build.gradle中的依赖关系

Answer 1

如前所述on this comment，您必须自己编译所有内容。在android/app/build.gradle。

中添加此内容

我不知道你是否有完全相同的问题，但每当我遇到dex问题时，这就是解决方案。

  compile "com.google.android.gms:play-services-base:11.4.2"
  compile "com.google.android.gms:play-services-base-license:11.4.2"
  compile "com.google.android.gms:play-services-ads:11.4.2"
  compile "com.google.android.gms:play-services-ads-lite:11.4.2"
  compile "com.google.android.gms:play-services-ads-license:11.4.2"
