In legacy/trac#27431 and legacy/trac#27375, it was reported Android is leaking DNS requests. From [ticket:27431#comment:1 27431], in summary: ``` This is exactly what we feared. It looks like this is the result of a bug within the Android core HTTP library. This leak is already fixed in the more recent releases of Android. In particular, any version after Android O (API 26+) should not leak DNS queries. ``` We should patch TBA so it relies on the Android core library as little as possible. We don't need the fancy optimizations Android provide with request pools and such, so I think we can simply create and manage a proxy connection ourselves. legacy/trac#27822 maybe related (but there isn't enough info available).
