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)
