I've done some work on this. Android is a very toxic environment for this sort of thing, primarily due to draconian filesystem permissions and aggressive killing of services. It's all in the name of security and battery life, but I wish there were an easy way to turn that all off for selfhosting. I've also seen people mention that apparently the flash memory doesn't do well with server type workloads, but a lot of that could probably be mitigated with logging to RAM, using a CDN, etc.
