Java Question Compilier - UNEXPECTED TOP-LEVEL EXCEPTION

[BobsYourUncle]

Hi All,

Both the Net library and my own library reference an external jar. The jar is mime4j.

Because both libraries are referencing the same library, the compilier/dexer is adding the same class name twice and causing a problem. Here's the error message:-

Compiling generated Java code.          1.21
Convert byte code - optimized dex.      Error
UNEXPECTED TOP-LEVEL EXCEPTION:

Does anyone know how to solve this problem? Any help would be really appreciated.

Kind regards,

You can remove this jar file (or classes) from your library jar.

Thanks Erel.
How do I exclude or delete the conflicting Base64OutputStream class from my library jar?

You can open the jar file with a zip program and delete it.
