我已下载并将xstream-1.4.8.jar添加到我的
Android Studio项目中.当我构建项目时它工作正常,但是当我尝试运行它时,我从Gradle Build窗口中收到以下错误:

提前致谢.
XStream 1.4.8是针对Java 8编译的,Android支持的最新版本是Java 7.
一种解决方案是使用适用于Android的XStream 1.4.7,另一种解决方案是下载XStream 1.4.8源代码并自行编译.在这种情况下,您将不得不删除Lambdamapper.java以及可能的其他一些有问题的类.
此外,您可能会遇到使用不同版本的xmlpull解析器的问题.在这种情况下,您可以从编译中排除一个.
compile('com.thoughtworks.xstream:xstream:1.4.7') { exclude group: 'xmlpull',module: 'xmlpull' }
