Question

我一直在尝试使用Android项目设置gwt，并在将sdk添加到我的构建路径后，编译就会出现这个问题。

我正在使用IntelliJ Ultimate 13.1，Android应用程序是随附的骨架。

这是完整的追溯：

披露：我从未做过任何严肃的Android开发者，而且我实际上并不知道＆＃34; pre dex＆＃34;真的意思是。

绝对没有理由将gwt-user打包到Android应用中。

要么包装由GWT生成的JS，你只需要在编译时使用GWT;或者您想使用RequestFactory，您应该使用requestfactory-client.jar。在其他情况下，您可能希望使用不在requestfactory-client中的其他GWT类（例如RegExp或SafeHtml），在这种情况下，您必须提取它们进入你自己的JAR，或者只是使用gwt-servlet。

Pre Dexing gwt-user.jar导致垃圾收集器出现OutOfMemoryError
