    Obfuscation

    Hi,

    I try to obfuscate my MIDlet but I can't.
    I made a game and tested it on a real phone: it works perfectly.

    Now I'm trying to obfuscate it with Proguard 1.7.2
    During the obfuscation I get this message:
    "warnig: can't write resoure entry [META-INF/MANIFEST.MF] can't add manifest file as an ordinary zip entry."

    But I get an output file, so I try to add the manifest by myself... it installs the midlet on the phone but it won't run.

    So I tried to preverify after obfuscation but it seems to be a problem there's always the same error that's not very explicit:
    "Jar file creation failed with error -1". It tells me that preverified classes are in tmp/41: all the classes are there!! (I had this error trying to preverify the output jar of Proguard AND the original jar before obfuscation)

    If someone has idea to help me, it's welcome :-)


    Thanks, thanks, thanks

    Heh, I had same error yesterday making Ant makescript, and forgot how I solved it

    Maybe you try to save preverified file to the same name as original one?
