Subsystem
Client
Motivation
On Android UrlConnection by default doesn't support HTTP/2, and is an old stack.
HttpEngine is now part of the Android 14 APIs (API 34+), and supports HTTP/2, HTTP/3 and much more advanced features.
Apps can install this as the process singleton URL handler, but this could have other impacts.
Solution
Rather than switching to the very different API HttpEngine, this change minimises the differences by using
HttpEngine.openConnection(URL)
and otherwise working the same as the existing UrlConnection code.TODO
