依据用户提供的 1.4.7 现场日志(21 行,5 次点歌全部成功)复盘出四点: 1. 【行为,最大】每次点歌白等 15 秒。 日志里每首歌前都有一条「JS-BRIDGE 15s 未就绪」,紧跟着「NATIVE-SONG 取址成功 用时=3xx~7xxms」—— 即取址本身只要 0.3~0.7 秒,但用户从按下点歌到开始下载要等 15.7 秒。 原因: 桥一旦不可用,SongApiClient 每次都仍等满 15 秒。 修复: KtvJsBridge 新增「已判定不可用」状态(markUnavailable/isUnavailable), 首次判定后后续点歌直接走原生通道;桥万一恢复(热更新重载成功)自动清除该状态。 2. 【日志去噪】持久状态只记一次。 原来「15s 未就绪」按每次点歌一条 WARN 输出,一天几百条且无新增信息。 现在只在状态首次变化时记一条 ERROR。 3. 【可定位】补上"为什么不可用"。 旧日志里没有任何 KtvApi 未导出/WebView 初始化失败的行,说明 init 回调根本没触发。 KtvJsBridge.init 增加 20 秒看门狗: onPageFinished 未回调时明确上报 「初始化超时:onPageFinished 未回调或 KtvApi 未导出」; init 异常与 KtvApi 未导出也统一收敛到 markUnavailable。 4. 【上下文完整】启动关键行不再有 undefined。 旧日志的 STORAGE 行 serverip/clientip/user/traceid 全是 undefined(记在设备上下文之前), 而且 AppPaths.storageFacts() 会真实建目录、写探针、读 /proc/mounts —— 却跑在主线程。 现在把 STORAGE 移入 reportDeviceBootInfo() 的后台线程、在 refreshLogDeviceContext() 与 MiliLog.awaitServerIp() 之后上报: 上下文完整且不再阻塞主线程。 5. 【新增状态样本】每 6 小时一条 HEALTH(版本/在线/可用空间/曲库是否存在及大小/根目录)。 日志此前只有事件没有状态样本,无法排查"随时间变化"的问题(空间变少、曲库丢失、长期离线)。 6. 【字段一致】「请求源=」不再为空: 走原生兜底时 JS 的 reportSongResult 不会触发, 现在 SongUrlResolver 记录 lastHost,SongApiClient.lastSongSourceHost() 依次回退。 AGENTS.md 增补「写日志的五条约定」(只记一次/上下文完整/不做重活/可自我定位/状态样本+事件)。 版本 1.4.7(27) 到 1.4.8(28);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>.
