+## 项目概述
+
+**a2i** — 安卓通知转发到 iOS Bark。监听 Android 系统通知（短信、验证码、聊天等），通过 Bark Server 推送到 iOS 设备。iOS 端点击通知可跳转到对应 App（微信、QQ、Telegram）。
+
+## 环境配置（本机）
+
+环境变量需要在每次 shell 调用前显式导出：
+
+```bash
+export JAVA_HOME="D:/Dev/JDK-17"
+export ANDROID_HOME="D:/Dev/Android/SDK"
+```
+
+- JDK 17: `D:\Dev\JDK-17`（项目使用 `sourceCompatibility = VERSION_17`）
+- Android SDK: `D:\Dev\Android\SDK`
+- Gradle 8.11.1（wrapper 内置）
+- AGP 8.9.1 / Kotlin 2.1.0
+
+`local.properties` 已在项目根（`sdk.dir=D:\Dev\Android\SDK`），**不要提交**。
+
+## 构建与安装
+
+```bash
+# 编译 debug APK
+export JAVA_HOME="D:/Dev/JDK-17" ANDROID_HOME="D:/Dev/Android/SDK"
+./gradlew assembleDebug
+
+# 产物位置
+app/build/outputs/apk/debug/app-debug.apk
+
+# 安装到已连接的设备
+"D:/Dev/Android/SDK/platform-tools/adb.exe" install -r app/build/outputs/apk/debug/app-debug.apk
+```
+
+无 lint / 测试任务配置（项目未启用）。改完代码直接 `assembleDebug` 验证即可。
+
+## 架构
+
+### 核心数据流
+
+```
+NotifyListenerService (系统通知入口)
+  → NotificationProcessor.process(sbn) → Decision(message, reason, code)
+  → BarkClient.push(msg) → OkHttp POST
+  → LogStore.addLog(...)
+失败 → 加入 pending → RetryWorker (WorkManager, 15min 周期)
+```
+
+### 包结构 `com.a2i.forwarder`
+
+| 文件 | 职责 |
+|---|---|
+| `A2iApp.kt` | `Application` 单例；持有全局 `appScope` 和三个 Store（`settings`、`appRules`、`logStore`）。Store 都用 `MutableStateFlow`，UI 通过 `collectAsState()` 订阅。 |
+| `service/NotifyListenerService.kt` | `NotificationListenerService` 实现；每条通知调 `processor.process()`，过滤后推送。 |
+| `core/NotificationProcessor.kt` | **核心决策点**。包含 LRU 去重缓存（5s）、脱敏检测（`*****` → 回退到 `tickerText`）、系统状态消息过滤、广告过滤、验证码提取、特殊 App 解析。返回 `Decision(message?, reason, appLabel, code)`。 |
+| `core/CodeExtractor.kt` | 三段正则：关键词+数字、数字+关键词、纯数字 4-8 位。检测到全 `*****` 时直接返回 null。 |
+| `core/AdFilter.kt` | 内置营销关键词 + 用户自定义关键词（`settings.adKeywords`）。 |
+| `core/AppParsers.kt` | 微信/QQ/Telegram 的 `clickUrl` 映射 + 重要消息关键词（@我、验证码、通话等）。 |
+| `core/BarkClient.kt` | OkHttp POST 到 `${server}/push`，超时 10/10/15s。 |
+| `core/RetryWorker.kt` | WorkManager 周期任务，每 15 分钟重发 `pending` 队列中的失败消息。 |
+| `core/LogStore.kt` | 最近 300 条日志 + 失败重发队列（≤100）。DataStore 持久化。 |
+| `core/IconExporter.kt` | 一键导出所有已安装 App 图标到用户选择的 SAF 目录（用于部署到 iOS Bark 图床）。 |
+| `store/SettingsStore.kt` | Bark 服务器列表、全局开关、广告关键词等。`MutableStateFlow` + DataStore。 |
+| `store/AppRulesStore.kt` | 黑/白名单模式 + 默认黑名单（系统 App + 三星剪贴板/键盘 + GMS）。 |
+| `ui/nav/AppNav.kt` | 4 个底部 Tab + 日志页。 |
+| `ui/screens/*.kt` | HomeScreen（首页统计 + 版本号）、AppManageScreen、FilterScreen、SettingsScreen、LogScreen。 |
+| `ui/Components.kt` | `appVersionName(context)` 工具函数用于显示版本号。 |
+
+### 重要约定
+
+- **Store 全局单例**：所有 Store 通过 `A2iApp.instance.xxx` 访问。**不要**在 Compose 中创建新的 Store 实例。
+- **协程作用域**：跨屏调用用 `app.appScope.launch { ... }`（Application 级别的 `SupervisorJob + Dispatchers.Default`）。
+- **过滤流水线**（顺序很重要，在 `NotificationProcessor.process` 中）：
+  1. 全局开关 → 2. ongoing 过滤 → 3. App 黑/白名单 → 4. 空内容/脱敏 → 5. 噪音包名 → 6. 系统状态消息 → 7. 近空内容 → 8. 广告过滤 → **9. 去重检查（5s 窗口）** → 10. 验证码提取 → 11. 特殊 App 解析 → 12. 构造 BarkMessage
+- **Bark API** 字段映射在 `BarkMessage.kt`（`@SerialName`）：`device_key`/`autoCopy`/`isArchive` 用下划线/驼峰别名，其他用蛇形。
+- **版本号**：`app/build.gradle.kts` 的 `versionCode`/`versionName`，运行时通过 `appVersionName(context)` 读取，首页底部居中显示 `v{version}`。改完代码记得同步递增。
+
+### 通知监听授权
+
+监听服务依赖 `Settings.ACTION_NOTIFICATION_LISTENER_SETTINGS` 授权。`HomeScreen` 检测授权状态，未授权时显示跳转按钮。授权是**一次性**的，卸载后需重新授权。
+
+### 调试日志
+
+`NotifyListenerService.handle()` 每次都会写一条 `ForwardLog` 到 `LogStore`（无论转发/过滤/失败），可在「日志」页查看最近 300 条。失败会自动加入 `pending` 队列，由 `RetryWorker` 后续重发。

+#   Gradle start up script for POSIX generated by Gradle.
+#
+#   Important for running:
+#
+#   (1) You need a POSIX-compliant shell to run this script. If your /bin/sh is
+#       noncompliant, but you have some other compliant shell such as ksh or
+#       bash, then to run this script, type that shell name before the whole
+#       command line, like:
+#
+#           ksh Gradle
+#
+#       Busybox and similar reduced shells will NOT work, because this script
+#       requires all of these POSIX shell features:
+#         * functions;
+#         * expansions «$var», «${var}», «${var:-default}», «${var+SET}»,
+#           «${var#prefix}», «${var%suffix}», and «$( cmd )»;
+#         * compound commands having a testable exit status, especially «case»;
+#         * various built-in commands including «command», «set», and «ulimit».
+#
+#   Important for patching:
+#
+#   (2) This script targets any POSIX shell, so it avoids extensions provided
+#       by Bash, Ksh, etc; in particular arrays are avoided.
+#
+#       The "traditional" practice of packing multiple parameters into a
+#       space-separated string is a well documented source of bugs and security
+#       problems, so this is (mostly) avoided, by progressively accumulating
+#       options in "$@", and eventually passing that to Java.
+#
+#       Where the inherited environment variables (DEFAULT_JVM_OPTS, JAVA_OPTS,
+#       and GRADLE_OPTS) rely on word-splitting, this is performed explicitly;
+#       see the in-line comments for details.
+#
+#       There are tweaks for specific operating systems such as AIX, CygWin,
+#       Darwin, MinGW, and NonStop.
+#
+#   (3) This script is generated from the Groovy template
+#       https://github.com/gradle/gradle/blob/HEAD/platforms/jvm/plugins-application/src/main/resources/org/gradle/api/internal/plugins/unixStartScript.txt
