Integrity requirements

• I confirm that I have read the documentation, understand the meaning of all the configuration items I wrote, and did not pile up seemingly useful options or default values.
• I confirm that I have provided the server and client configuration files and process that can be reproduced locally, instead of a complicated client configuration file that has been stripped of sensitive data.
• I confirm that I have provided the simplest configuration that can be used to reproduce the error I reported, instead of depending on remote servers, TUN, graphical interface clients, or other closed-source software.
• I confirm that I have provided the complete configuration files and logs, rather than just providing parts I think are useful out of confidence in my own intelligence.

Start by reproducing the crash when connecting through the Android UI, then inspect dns/transport_registry.go and dns/transport_manager.go at the logged stack frames, followed by box.go and experimental/libbox/service.go. Trace the RawLocalDNSServerOptions versus LocalDNSServerOptions mismatch and verify that the reported Android connection no longer aborts.
