Hello, I would like to share this java decompiler with the community. FernFlower is the first analytic decompiler for java. It will decompile class files and jar files to human readable java code. Unlike JD-GUI it does not decompile to byte code. It also will deobfuscate the source if you ask it to. This tool should work well with dex2jar. The files are attached. It requires java to run.

I take no credit for creating this tool. I will still however release the decompiled and deobfsucated source code.

Sorry for reviving that old thread, but this is currently the first Google result for "fernflower", so I think it would be nice to post here to guide people looking for more information about this decompiler. Fernflower should get more popular now, since it is integrated in the IntelliJ IDEA version 14 IDE, which is very popular including among Android developers.

The source code posted by ostar2 was decompiled from the Fernflower binaries. The good news is that the original sourcecode is now available and under Apache license.

It includes the standalone decompiler which can be used outside of the IDE:

CLASSPATH=java-decompiler.jar java
