现场日志(1.4.8)显示启动瞬间就出现: 20:46:59.636 NET-UP 设备网络已恢复, 重建歌曲源会话 20:46:59.647 NET-REFRESH reason=net-up retried=0 20:46:59.980 BOOT 即 NET-UP 出现在 BOOT 之前 —— 启动被当成了"断网后恢复"。 根因: KtvNetworkMonitor.start() 末尾无条件 onChange(initial)， 注册 ConnectivityManager 回调时系统会回报一次初始状态，上层把它当成了状态跃迁。 而启动流程(onCreate)已经做过 startRemoteServer()/updateMobileQrOverlay()/ refreshLogDeviceContext()/DeviceMac 解析，所以这次"恢复"是纯粹重复劳动，且有副作用: - SongApiClient.resetSourceSession() 白清掉刚建立的歌曲源会话; - Eac19WindowGuard.noteUrlOk() 语义错误(还没取到任何地址就标记窗口正常， 可能掩盖真正的歌曲源窗口到期提示); - 状态栏被写成"网络已恢复"(启动瞬间就显示，用户可见的错误文案)。 修复: - KtvNetworkMonitor.start/refresh 的回调签名改为 (online, initial)， initial=true 表示"注册时的初始状态"; - MainActivity.onNetworkStateChanged(online, initial): 初始状态**只更新断网角标**， 不做任何恢复动作；恢复动作(重建会话/重启点歌服务/刷新二维码/重试下载) 只在真正的 offline→online 跃迁时执行。 同时补齐 WebView 失效原因的取证(旧日志只有"KtvApi 未导出"这一句，无法定因): - wrapHtml 注入特性探测: 上报 WEBVIEW ua=... asyncFunction=yes|no promise=... (用 new Function 探测，避免探测语句自身引起语法错误)。Android 5.x 的 WebView 可能是 Chrome 39~4x，不支持 async/await 会让**整个 ktv_api.js 语法报错** → window.KtvApi 未定义、桥永远不就绪，这条日志可直接确证; - window.onerror 上报脚本解析/运行错误(JS-ERROR ... @line:col)，语法错误也会触发; - 合并重复的失败行: "JS-BRIDGE 初始化返回 false" 与 "JS-BRIDGE 判定本机 WebView 不可用" 只保留后者(含原因)。 版本 1.4.8(28) 到 1.4.9(29)；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>.
