现象: 极米 H1S 上曲库开始下载后速度极慢，并有概率卡死（ANR）。 根因: MuseDbSync.downloadFile 每读一个 256KB 分块就回调一次进度， 430MB 压缩包 = 约 1700 次回调；每次回调都 main.post -> showDatabaseLoading()， 而该函数每次刷新都在主线程做: setText + 改 ProgressBar + setOnClickListener(null) + bringToFront() （bringToFront 会让整棵视图树 requestLayout）。 1700 次全屏布局把主线程 Looper 队列压满 -> 界面停止响应（卡死）； 同时整机 CPU 被布局任务吃掉，网络线程与 FUSE 写盘都被拖慢 -> 下载本身也变慢。 两个症状同一个根因，不是网络问题。 修复: - 进度回调两级去重: MuseDbSync 按百分比去重; MainActivity 按最终显示文案去重， 刷新次数从约 1700 降到不超过 100。 - showDatabaseLoading 更新路径只做真正变化的事: 文本不同才 setText、进度不同才改 progress、不再每次 bringToFront()、不再每次重设监听。 - 解压(约 1GB)与 md5 校验(430MB)阶段补上进度明细（例如 正在解压曲库 512MB）， 避免界面长时间停在某个百分比被误判为卡死。 - 下载速率按每 10% 上报远程日志: MUSE-DB progress 30% 129MB/430MB 1.85MB/s， 可直接区分网络慢还是磁盘慢。 - 回调签名 (Int)->Unit 扩展为 (Int, String?)->Unit 以携带明细文案。 - AGENTS.md 增补 高频回调不能直接刷 UI 条目。 版本 1.4.3(23) 到 1.4.4(24)；签名证书不变。

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>.
