Two of the three Radio Browser hosts this client shipped no longer resolve.
The retry loop rotates de1 -> nl1 -> at1, so once the first attempt failed
for any transient reason the remaining two were guaranteed to fail as well:
the retries meant to add resilience had become a dead end, and a single blip
surfaced as "No connection to the radio API" with a healthy API and a healthy
network. The live mirror list confirms only one server remains:
[{"ip":"91.98.4.78","name":"de1.api.radio-browser.info"},
{"ip":"2a01:4f8:1c1d:699::1","name":"de1.api.radio-browser.info"}]
The API docs say exactly what this code was doing wrong: "Never use a direct
link to a single new server. It is much better to get a list of the servers",
pointing clients at all.api.radio-browser.info to enumerate what exists.
Seed with that round-robin host plus de1, then resolve the real list from
/json/servers once per instance and rotate over that. Discovery shares one
in-flight request across concurrent callers, because the home screen loads
two lists at once through Future.wait, and any failure silently leaves the
seed list in place — it still contains a working host, so a failed discovery
must never be worse than not trying. Explicitly injected servers disable
discovery so callers can still pin a mirror.
Build the User-Agent from the running package too. The API asks clients to
identify themselves, and this header claimed PluriWave/0.1.0 while the app
shipped 1.1.x. A literal cannot stay correct here — CI bumps the version on
every single release — so read it via package_info_plus, already a dependency
used in three other places. If package info is unavailable the product name
goes out alone rather than a made-up version, and resolution never throws: a
header must not be able to fail a request.
