真正根因（用崩溃诊断包在该机上逐步定位得出，非此前推测的 API 守卫问题）: - AppPaths 把存储根写死成 /storage/emulated/0/MaidongKTV，该机上此路径不可写， ensureDirectories() 里 check(it.exists() || it.mkdirs()) 抛异常 → onCreate 中断 → App 一打开就闪退（该机历来所有版本均如此）。 - 定位过程: 逐条语句打启动轨迹 + 把异常直接写进轨迹通道，最终锁定 「oc431 之后、oc432 之前」= AppPaths.ensureDirectories()；包上 try/catch 后 App 立即可正常打开，确认根因。 修复: - AppPaths 改为运行时解析可写根目录: Environment 外部根 → 历史硬编码路径 → getExternalFilesDir() → filesDir，取第一个「可建且可写」的（幂等 init）。 - AppPaths.init(context) 在 KtvApplication.attachBaseContext 最前面调用， 早于任何 AppPaths 访问；路径成员由 val 改为 getter。 - ensureDirectories() 不再抛异常，返回 Boolean；MainActivity 拿到 false 只告警继续。 - 去掉编译期内联的路径常量: MuseDatabase.VIDEO_ROOT(const→getter)、 defaultDbFile()/findDatabaseFile() 改用 AppPaths.databaseFile （否则改存储根后 DB 仍指向硬编码路径）。 - 用户可见的目录提示文案改用 AppPaths.*Dir.absolutePath。 - 启动上报一行 STORAGE root=.. by=.. envState=.. probe=[..] 到远程日志， 便于排查不同盒子的存储差异。 验证: - DEX 中「内联的完整 DB 路径」由 1 处 → 0 处。 - 单元测试 2/2 通过；lint NewApi 闸门通过；签名证书不变（可覆盖 1.4.0/诊断包）。 - AGENTS.md 增补「存储根目录必须运行时解析」条目。 说明: versionCode 18~21 被本机临时诊断包占用，本版取 22 以便直接覆盖安装。

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>.
