App doesn't run on device if LWUIT is obfuscated
I have just set up a demo app that basically puts a form on the screen and writes Hello World. I have written an Ant script that compiles and builds and packages and it all works fine on a real device. As soon as I obfuscate using Proguard (tried version 4.0 and 4.3) the app doesn't work. The device just reports an exception when starting. I am using Antenna and therefore the wtkobfuscate task.
Any ideas how I can obfuscate and still get the app to run on the device?
