现象: 极米 H1S 上报告「曲库分区空间不足(当前可用 6.04 GB)」——数字自相矛盾。 核实(本地实测 Muse 协议): - 曲库压缩包 430,575,974 字节;从 gzip 尾部 ISIZE 读出解压后为 965MB, 峰值占用约 1.4GB,6.04GB 可用空间根本不构成空间不足。 - 结论: 真正抛出的异常另有原因(消息里含 no space left), 被 isNoSpaceError() 只按消息文本匹配而误判成了"空间不足"。 修复: - readableError 不再只看异常消息: 报告完整异常链 + 可用空间, 并用真实写入探针(AppPaths.probeWrite,写 8MB 再删)区分 "真的写不进去" 与 "其实能写"(inode 耗尽/配额/ROM 限制同样报 ENOSPC, 而 usableSpace 仍显示数 GB)。 - 失败时上报单行完整诊断到远程日志: DB-SYNC download failed | <异常链> | root/free/total/envState/probe/proc-mounts。 - 界面失败文案直接显示原始异常,不再用可能误导的"空间不足"结论。 - AppPaths 新增 probeWrite() 与 diagnose()(含 /proc/mounts 相关挂载点)。 - MuseDbSync 失败时同时清理 muse.db.gz.download 与 muse.db.download: 原先失败只删前者,残留的 965MB 分片在反复重试时会白占空间。 版本 1.4.4(24) 到 1.4.5(25);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>.
