现象: 新设备公放时按「切歌」没有任何反应。 根因(我上一版引入的回归): - 1.4.10 为了让"被当成歌曲缓存下来的广告视频"消失,在启动时做了一次 **整目录清理**(删 cloud-song 下所有 .ts/.ls/.mp4/.mkv)。 - 但 MuseDatabase.songDirectories() **只有 cloudSongsDir 一个目录**, SongOkDownloadManager.getLocalFile() 也落在那里 —— 那等于**把公放曲库整个删掉**。 - 后果链: 库空 → playRandomLocalSong() 里 allLocalSongs 为空 → RandomPlayQueue.next() 返回 null → 状态栏"本地暂无可播放歌曲"、currentSong 保持 null → 按「切歌」时 advancePlayback 落进「取消随机续播、进入空闲态」分支 → 按钮无反应。 (RandomPlayQueue.next 本身有"只剩一首也能播"的兜底,队列逻辑没问题。) 修复: - 删除整目录清理,改为 purgeInjectedAdDuplicatesOnce(): **只删能证明是注入广告的文件** —— 广告对每首歌下发同一个视频,特征是"多首不同歌曲的本地文件内容完全相同" (按文件大小 + 头部 4MB 指纹分组,只清理 size>=2 的完全相同组)。 正常歌曲内容各不相同,绝不会被误删;公放曲库得以保留。 同时按用户要求,复查"老设备适配期间改动对新设备的影响",另修正两处: - SongApiClient.getSongDownloadUrl 的主线程分支: 1.4.7 起会先走 resolveNatively() (最多 7 个源 × 8 秒超时的阻塞网络请求)—— 一旦有主线程调用者就会卡死 UI 到 ANR。 现在主线程只做本地 DB 兜底,网络取址一律留在后台线程。 - KtvJsBridge 裸 Socket 的 HTTPS 分支: 1.4.6 改用了无参 createSocket(),拿到的 SSLSocket **不带主机名**(影响 SNI 与证书主机名校验,共享 CDN/反代多证书时会握手失败)。 改为先 connect 普通 socket(保留显式连接超时)再 createSocket(plain, host, port, true)。 - buildDownloadUrl 的文件名比对只在点歌编号"可信"时启用: 只有从 song.filename 推出的编号才 参与比对;song.id 可能是数据库主键,拿它比对会误杀正常地址(真源被判"文件名不符")。 (另已实测 7 个源: 可用的 5 个真源 URL 文件名全部严格等于点歌编号,规则不会误杀。) 顺带记录用户给出的版本号约定(已写入 AGENTS.md): versionName = <major>.<minor>.<patch>,patch 0~10、minor 1~10; 1.4.10 之后是 1.5.0,1.10.1 之后是 2.1.0;versionCode 始终 +1。 版本 1.4.10(30) → 1.5.0(31);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>.
