Q:

Imported classes are prefixed in Client Library

In Python I'm creating backend for my Android app.  My code is too big so I broke it to 2 files with functions and one with shared classes (shared_classes.py) which inherit from messages. Message. 
When I generate client library, all classes get prefixed with name of the python file I stored them in (they look like: SharedClassesExampleName.java).  
Is it possible to force endpointscfg.py to stop generating library with prefixed python classes? 

A:

As described on this page (in step no.  4)
The "package=" line is used by the underlying ProtoRpc when creating names for the ProtoRPC messages you create.  This package name will show up as a prefix to your message class names in the discovery doc and client libraries. 
So you if you encourage this problem just add package=' ' (empty value) and your classes will not be prefixed.
