R8 only ever ran on `release`, so every automated gate in this repository
exercised code the shipped APK does not contain. Reflective lookups, JNI
callbacks and native library loading can all break under shrinking while
`flutter test`, the Robolectric suites and `connectedDebugAndroidTest`
stay green — which is exactly how #1703 shipped, with the bundled FFmpeg
audio renderer shrunk out of release builds for TrueHD and DTS-HD.
Add a `minified` build type that inherits release's shrinker
configuration but stays debuggable and debug-signed, so it is an ordinary
test artifact and never a publishable one. Three integration details
took a run each to find: the Flutter plugin copies app build types into
every plugin module, so library-level shrinking deleted the plugin entry
points that only GeneratedPluginRegistrant references; the harness must
not be shrunk or the runner disappears; and androidx.test has to survive
in the app under test, or the runner cannot link its own supertype and
the run reports zero tests instead of failing.
Instrumentation still defaults to `debug`, because only one build type
can host androidTest and the existing playback suites drive media3
builder APIs the app never calls, which R8 shrinks legitimately. The new
reachability test opts into the minified variant instead and touches no
builder API, so the only keeps it depends on are the ones under test.
Emptying proguard-rules.pro was verified to fail it.
Four regression flows, each run on a Pixel 7 and, where relevant, a real
Android TV box.
Discriminating — the baseline fails, HEAD passes:
`07_sheet_back_dismiss` pins both halves of the hosted-sheet fix on touch: the
barrier removes the rows behind it from the semantics tree, and one Back closes
only the sheet while Settings stays the current route, including the nested
per-library options page. It fails on c48cbf70, the commit before 8e1904dd.
`03_tv_library_focus` gains the same occlusion assertion for the TV sort sheet
and fails there too.
`08_track_choice_survives_pending_pass` picks a non-default audio and subtitle
track, lets playback outlive the automatic pass's 5s attempt and 25s deadline,
and asserts the choice is still selected. On a56b9a3d the audio reverts to the
container's default. Both new flows onboard from a cleared install: the TV
regressions in the same group leave "Force TV mode" enabled, and a remembered
track selection would pre-select the rows under test.
Coverage without a comparable baseline:
`09_language_picker_locales` asserts the four new endonyms, switches to Turkish,
reads root navigation labels from the generated locale, and restores English.
The locales do not exist before 7677d159/100d7729, so there is nothing to fail
against — this is forward coverage, not a reproduction.
`10_tv_settings_navigation` runs on real Android TV hardware, which no existing
flow covers: the rail layout a device reports on its own, the TV dialog path for
Manage Libraries, the Apple-only Atmos gate staying closed on Android, and the
D-pad-only route to the number spinner's accessibility labels, which a single
tap would hide. It passes on either side of the range and is verified against
both an empty server and one with a resume position, since rail order shifts
with that. It does not assert the 15b54e2e row density: that change is invisible
to a semantics-tree driver, and a pixel `height` assertion would only hold for
one DPR. It registers under a new `android-tv-device` group no workflow
dispatches.
No TV playback flow is included. Entering content on the TV Recommended view has
no stable anchor: the accessibility `focused` flag sits on the hero backdrop
rather than the rail card, and a resume position anywhere in the library pushes
"Recently Added" below the fold and out of the semantics tree entirely. Search
is not a way around it either — inputText does not reach the TV search field.
Covering TV playback needs a testID on the rail card, not a cleverer selector.
Also repairs three assertions that could never fail:
`03_tv_library_focus` gated the sort sheet closing on `notVisible: "Sort by"`,
but the header renders "Sort By" and Maestro selectors are case-sensitive
regexes, so the wait returned immediately and the next D-pad press landed in the
sheet's close animation.
`open_codec_sample` matched a card's watch state as `watched|unwatched` only. A
codec sample keeps a resume position once any earlier flow has played it, so the
row announces "N percent watched" and the subflow stopped finding it on a
fixture container that outlives one suite.
`06_playback_recovery` tapped "Zulu Zone" out of the Recently Added rail, but
every seeded alphabet title shares one dateadded, so which of them the rail
returns is a tie-break. The flow only needs some playable movie.
The legacy playback group repeatedly failed to see any Jellyfin server
while the container reported healthy, because the API 28 image routes
the 10.0.2.2 host alias unreliably. Uses the runner's existing reverse
mapping, as the media suite already does on API 35, so the app connects
over 127.0.0.1 instead. No assertion is weakened.
