Summary

• Startup crash ([Bug]: FileNotFoundException in IoBridge.java:569 #1355, [Bug]: FileNotFoundException in IoBridge.java:569 #1362): DataStore 1.1.1 to 1.1.7, which retries the first read that raced the file's creation. Every preferences store now retries a failed read and then falls back to defaults instead of crashing. The crash screen shows a report once instead of on every launch.
• Status bar ([Bug]: Status bar icons not showing #1375): the expanded video player counts as drawing under the status bar, so the icons turn light over its black strip in light theme.
• System equalizer ([Bug]: "System Equalizer" Does Not Work #1373): since Media3 1.6 the audio session id arrives after the player is built, so it was always read as 0 and never announced. A new AudioSessionAnnouncer listener opens each session when ExoPlayer reports it and makes the playing player the system equalizer's session. The panel is built at tap time with that session, and the loudness gain is applied once the session exists. Listeners only, player construction unchanged.
• Playlists ([Bug]: Missing videos in playlist #1358): Shorts-only playlists arrive as a grid of 100 with no next page; the grid is parsed and re-requested once as the full list. One page walker replaces three loops, and a walk that did not finish is never cached or synced over a saved copy. The header says when YouTube hides unavailable videos. The playlist request no longer reads NewPipe's client version.
• Bot wall ([Bug]: Youtube Is blocking this network since 3.0.0 (Thread) #1354): when every client is walled at /player, Flow re-rolls the visitor once and walks the ladder again; the first re-roll on a new network skips the shared budget. The error panel offers Reset YouTube session. The message names the network only when a fresh visitor is walled too, and mentions a VPN only when one is on. Diagnostics log the web clients' walls and the visitor's age and network.

Change type

• Bug fix
• Feature
• Refactor or maintenance
• Build, packaging, or CI
• Documentation

Validation

• ./gradlew :app:assembleGithubDebug
• ./gradlew :app:testGithubDebugUnitTest (4,276 tests, 0 failures)
• I ran any additional flavor-specific build or test tasks affected by this change. (ktlintCheck, :app:compileFossDebugKotlin, python3 .github/scripts/nightly_notes.py --check)
• I manually tested the affected behavior on an Android device or emulator.

New JVM tests: ReadSafeDataStoreTest, AudioSessionRegistryTest, AudioSessionAnnouncerTest, PlaylistWalkTest, plus new cases in VideoPlaylistPageTest, PlayabilityVerdictTest and VideoErrorMapperTest.

On the device:

• Shorts-only playlist from [Bug]: Missing videos in playlist #1358: 157 videos with the hidden-videos note; the 970-entry one: 776 videos with the note.
• Light theme: white status bar icons on the expanded player, dark icons once collapsed.
• dumpsys activity broadcasts: MusicFX receives the video (MOVIE) and music (MUSIC) sessions with real ids, re-announced when each starts playing.
• dumpsys media.audio_flinger with MusicFX switched on: Equalizer, Bass Boost and Virtualizer on Flow's playing music session; Flow's Loudness Enhancer on the video session.

Test device and Android version: Xiaomi 2311DRK48G, Android 16 (API 36)

Risk and compatibility

• DataStore stays on 1.1.x; the 1.1.1 to 1.1.7 diff of the storage code is only the first-read retry.

• The system equalizer change adds player listeners in the video player, the music service and the Shorts pool; how players are built, owned and released is unchanged.

• A Shorts-only playlist costs one extra browse request. A fully walled extraction costs one visitor fetch and one more pass of the client ladder, once per visitor.

• No preference migrations; the visitor store gains one key for the network the visitor was minted on.

• The change does not introduce secrets, private data, or unexpected telemetry.

• New user-facing text uses Android string resources.

• Dependency and lockfile changes are intentional and limited to this PR.

• Room schema changes include the required version bump and migration, or this PR does not change the Room schema.

• Breaking changes and upgrade steps are clearly documented.
