证据（用户导出的 1.4.6 远程日志）: - 两条失败记录只有 Kotlin 侧那一行 「点歌编号=... 详情=无法生成下载地址」， 而 JS ...（本版新加的 console 桥）、RAW-ERR、NET-ERR、点歌失败 一条都没有。 - 即 JS 侧从未执行 —— 隐藏 WebView 在这台盒子上从未就绪 （每条失败前正好有约 15s 的「等桥就绪」超时，时间吻合）。 - 于是 SongApiClient 只能回退 DB 的 cloud_url，取不到就报「无法生成下载地址」。 根因: 取址完全依赖 WebView 里的 ktv_api.js；GMUI2.0/Android 5.1.1 上 WebView 不可用（无法导出 window.KtvApi），桥永远 not ready。 修复: - 新增 SongUrlResolver: 用 Kotlin 复刻 ktv_api.js 的协议 （GET <host>/i.php 取 token → GET <host>/music/do.php 取地址）， 镜像多源排序（失败源沉底）与 isDemoUrl 校验（wb66/demo/纯IP/r2.dev/ts编号不一致）。 - 走与 JS 完全相同的裸 Socket「干净请求」通道（KtvJsBridge.rawCleanGet）， 请求特征一致故风控表现一致，且不依赖 WebView 是否就绪。 - SongApiClient.getSongDownloadUrl 三处回退点改为: 桥未就绪 / JS 未取到地址 / 主线程调用 → 先走原生解析，再回退 DB。 - 补齐桥的生命周期可观测性: WebView 初始化失败、KtvApi 未导出、 15s 未就绪 均写入远程日志（以前只在 logcat，这就是本轮一开始没有线索的原因）。 已用 App 的真实身份( mac=800b510bf4fd / sn=2d7bb4a7d7f7 / VER=2.0 ) 从本机复现协议: i.php 200 → do.php code=200 且返回 http://txog.ktvsky.com/.../480p/7303235.ts （与点歌编号一致）， 证明参数顺序与签名算法正确。 版本 1.4.6(26) 到 1.4.7(27)；签名证书不变。ktv_api.js 未改动，KTV_BRIDGE_API 仍为 8。

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>.
