Obfuscation and Native calls

[paulkeast]

Is there an 'emptied-out' version (i.e. no Native calls) of the Nokia API available or any plans to make one as the Native calls used (for example, when using a List) cause an 'Unsatisified Link Error' which means the no obfuscation can occur on the code, which given the small file limits in place can be vital.

I was able to obfuscate my midlet jar with RetroGuard using 'emptied-out' MIDP API which can be found at http://developer.java.sun.com/developer/qow/archive/161/emptyapi.zip

After running the preverifier on the obfuscated jar file, the midlet runs nicely on the 6310i emulator. But for some reason NOT on the actual phone! Any ideas why ?

In your 6310i emulator directory, there is a file called classes.zip, this file contains all the API you need. Include this file in your classpath when compiling.

When obfuscating, remember NOT to include all javax.* and com.nokia.* packages. This might be your problem.
