Start with the stack trace at StorageUtils.java:23 and LoggerFactory.java:86, then trace the proxy initialization through HttpProxyCacheServer.java and global_functions.java:377. Check how the Android build packages the SLF4J classes and reproduce the failure; done means creating the proxy no longer throws NoClassDefFoundError.
