现象: 点歌清单只剩最后一首且正在播放时按一下「切歌」，那首歌播完后 App 直接卡死 （之后按切歌/播放都没反应）。 根因（advancePlayback 的出口语义 + 僵尸态）: - orderQueue 是"已点清单"，正在播的那首**仍在队列里**；按切歌时才移除。 - 旧逻辑: 显式切歌移除最后一首后队列已空 → 落到"清空到空闲态"分支， 该分支把 currentSong 置空、playWhenPrepared=false，**却没有停播放器**。 - 于是那首歌继续播到结束；而 onCompletion 第一行是 `if (generation != playbackGeneration || currentSong?.equals(song) != true) return` → currentSong 已为 null，回调被**直接吞掉**，再也不推进。 - 结果就是"音频结束 / currentSong 为空 / 播放中标志为 false"的僵尸态： 再按切歌或播放都没有任何反应（用户看到的卡死）。 修复（完全按用户要求的状态机）: - 显式切歌且点歌清单已空（= 在最后一首上按切歌）→ **转入公放**（playRandomLocalSong(skipped)）， 不再清空到空闲态。公放清单与点歌清单互不影响：随机歌曲不入 orderQueue； 用户一点歌，挂起的随机请求会被 orderQueue.isNotEmpty() 守卫取消。 - 其它出口保持原逻辑不变（队列还有歌→下一首；自然播完+autoNext+队列空→公放； 手动模式自然播完→空闲）。 - 僵尸态兜底: 所有"清空播放状态"的出口都补上 `player.stopPlayback()` + currentMediaPlayer = null （空闲态分支、公放库为空的兜底分支）。唯一例外是马上 play() 下一首的路径—— 故意不停，避免切歌瞬间因曲库扫描而静音。 AGENTS.md 增补「切歌/续播状态机」四条出口 + 僵尸态的成因与强制约定。 版本 1.5.0(31) → 1.5.1(32)；签名证书不变。测试 8 例全通过。

Project Notice
This repository: https://gitea.kasugano.cn/zijunchiang/maidong-ktv
UI/feature framework credit: https://gitee.com/yangyachao-X/maidong-ktv
This repository reworks the upstream "Maidong KTV" UI and feature framework, and the core/data layer was rewritten with DSH (DeepSeek Harness): library sync, song-source integration, device auth, risk-control handling, remote logging, and ad blocking are all new implementations.
Highlights of the reworked data layer:
- Library: synced exclusively from the official Muse service
(
mconn.cherryonline.cnmls-api/v1/sqlite/sync); the code host carries source only, no database files. - Song source:
w.w345.my(i.phptoken →do.phpplayback URL) with fixed device identity and reproduced signing; ad/mismatched resources (e.g.wb66.cn/.../719.ts) are blocked and retried. - JS hot-update:
app/src/main/assets/mobile/ktv_api.js, requires theKTV_BRIDGE_API: 7marker.
Building
Requirements: JDK 17, Android SDK (compileSdk 35, minSdk 21, targetSdk 25),
Gradle wrapper 8.13 (bundled).
cd maidong-ktv
export JAVA_HOME=/path/to/jdk-17
export ANDROID_HOME=/path/to/android-sdk
export ANDROID_SDK_ROOT=$ANDROID_HOME
./gradlew assembleRelease
The release signing config in app/build.gradle expects ../../ktv_keystore.jks (one level above the
repo root) with alias ktv / password 123456; adjust paths or use signingConfigs.debug for a
quick unsigned build. Output: app/build/outputs/apk/release/app-release.apk
(dual ABI: armeabi-v7a + arm64-v8a). Install with adb install -r <apk>.
