-- Many of our APIs are shared between Android and Server, and we also run the client tests on desktop machines, so **stick to Java 8** unless you've verified that something newer is available on Android (back to our earliest supported version, API level 21, at the time of this writing), and don't use Android-specific APIs unless you're actually in Android-specific code. (This *should* be checked in CI but things have slipped through before, and it'll save you time to know whether you're allowed to use something.)
