Arggg!!! Amazon obfuscated many class names in recent firmware updates. I wasted some time trying to figure it out. This is much harder than I expected.
Thanks to ixtab, I grabbed the firmware 5.0.0 and extract the JARs from it. All the class and method names are back  . But it seems that the decompiler can't differentiate among local variables, all of them are named "a"  . Does anybody know how to fix this? |
No easy way to fix it. The decompiler decompiles correctly - the variables *are* all named "a" because of obfuscation. (Yes, even 5.0.0 is slightly obfuscated). You might be able to "rename" them by modifying the constants pool of the class file, and correctly "linking" the variables there. If you're lucky, there is some deobfuscator out there which can do that, but I don't remember seeing one. If you do find one, then I'm very interested in it, because yes, it's a PITA to read such code.
One more comment concerning 5.0.0/5.1.x/5.2.0: I'm also usually resorting to the 5.0.0 version to understand what's going on, and then try to matchmake with the newer version. Just remember that the code may change slightly between the versions (some parts also changed heavily), and that ultimately you have to figure out the patch for the code of the exact version that you want to support. Oh, and a hint: "jad -a" is your friend.
