Start with com.danikula.videocache.file.Files.makeDir and FileCache., then follow the request path through HttpProxyCacheServerClients and HttpProxyCacheServer.processSocket. Reproduce the failure using the reported external-storage cache path; done means the cache request no longer fails because the directory cannot be created, with video playback still working.
