有人试过在android开发中使用lambdaj库吗？
当我创建一个简单的小型 java 应用程序时，它对我来说工作正常，但我无法在 android 应用程序中使用它。
更新:
我正在添加 lambdaj(lambdaj-2.3.2-with-dependencies.jar，从 http://code.google.com/p/lambdaj 下载)，然后在构建我的应用程序时出现以下错误:
Dx warning: Ignoring InnerClasses attribute for an anonymous inner class
(org.hamcrest.generator.qdox.directorywalker.DirectoryScanner$1) that doesn't come with an
associated EnclosingMethod attribute. This class was probably produced by a
compiler that did not target the modern .class file format. The recommended
solution is to recompile the class from source, using an up-to-date compiler
and without specifying any "-target" type options. The consequence of ignoring
this warning is that reflective operations on this class will incorrectly
indicate that it is *not* an inner class.

最佳答案
我知道这个问题已有 4 年历史，但我现在遇到了同样的问题，我通过将最新的 hamcrest 库版本添加到我的 gradle 构建配置 depedencies 中解决了这个问题。
更新:
我在我的项目中遇到了 lambdaj 的问题，这个库不完全兼容。我搬到了 retrolambda，看看吧!
关于java - 在安卓中使用 lambdaj，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/5977100/
