app shrinking tricks

In 1999 I remember there were heaps of tools that could take an app complete with all of its jar files and carve out all of the unused bytecode. This was great for applets.

Now, I can see the value of doing something similar for trying to move something quickly to JME.

Are these kinds of tools still around?

Are you talking about an obfuscator which "zips" the Midlet's jar file? Yes, there are obfuscators out there for that.

Like this one

Or do you mean taking a J2SE program and automatically turning it into a J2ME program? That I have not seen considering that they are two different specs, and apis.

Mark is correct...

you can use obfuscators....

But you gotta also understand the consequences it can create based on the level you are looking at...

E.g. Less readability
