Using lambdaj in android

Question

Does anyone tried to use lambdaj library in android development?

It works fine for me when I create a simple small java application, but I can't manage to use it in an android application.

UPDATE:

I'm adding lambdaj (lambdaj-2.3.2-with-dependencies.jar, downloaded from http://code.google.com/p/lambdaj), and then when building my application get the following error:

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.

Answer 1

I know that this question is 4 years old, but I had the same problem nowdays and I solved by adding to my gradle build configuration depedencies the last hamcrest library version available.

here my related thread

UPDATE:

I had some problem with lambdaj on my project, this library is not totally compatible. I moved to retrolambda, check it out!

Answer 2

It looks to me like there is a problem with the hamcrest library. Try following the advice in the error and rebuild the hamcrest library from source.
