-# Cyrene for Android
-
-昔涟在安卓设备上的载体 —— 随时随地与昔涟对话、操控 IoT 设备、接收实时通知。
-
-## 概述
-
-Cyrene for Android 是 [Cyrene（昔涟）](https://github.com/Cyrene/Cyrene) 项目的官方 Android 客户端。Cyrene 是一个开源的基于 LLM 平台的智能体，提供多人格对话、IoT 设备操控、记忆管理、自动化规则、知识库、语音交互等功能。
-
-Android 客户端的目标是成为用户的**默认语音助手**，完全替代系统自带的助手（Google Assistant / Bixby 等），同时提供：
-
- **系统级语音助手** — 注册为 `VoiceInteractionService`，可通过长按 Home / 侧滑呼出
- **语音唤醒** — 息屏热词唤醒、免提交互（类似 "Hey Google"，使用 "昔涟" 等唤醒词）
- **随时对话** — 通过文字或语音与昔涟交流
- **IoT 控制** — 远程操控家中的智能设备
- **实时通知** — 接收昔涟的主动消息、提醒、IoT 状态变更
- **后台连接** — 即使 APP 在后台，仍保持通知推送与语音服务就绪
-
-## 开发状态
-
-> **当前阶段**：项目初始化，尚未开始正式开发。
-
-根据主项目的[开发路线图](../docs/dev-plan/00-development-roadmap.md)，Android 客户端计划在 **Phase 5（v1.5 → v2.0）** 开始开发，预计时间窗口为 **2027 Q2-Q3**。
-
-## 技术栈 (规划)
-
-| 层 | 技术 |
-|----|------|
-| 语言 | Kotlin |
-| UI 框架 | Jetpack Compose + Material Design 3 |
-| 架构 | MVVM + Repository |
-| 网络 | OkHttp / Retrofit + WebSocket |
-| 本地存储 | Room (SQLite) + DataStore |
-| 推送 | FCM (Firebase Cloud Messaging) |
-| 语音 | VoiceInteractionService + 热词唤醒 + STT + TTS |
-| 构建 | Gradle (Kotlin DSL) |
-
-## 功能路线图
-
- [ ] 用户认证与登录
- [ ] 实时文字对话 (WebSocket)
- [ ] VoiceInteractionService 注册（替换系统语音助手）
- [ ] 间接启动悬浮窗（VoiceInteractionSession 全屏覆盖层）
- [ ] 热词唤醒（息屏 / 亮屏）+ 唤醒词自定义
- [ ] 语音识别 (STT)
- [ ] 语音合成 (TTS)
- [ ] IoT 设备控制面板
- [ ] 推送通知 (FCM)
- [ ] 后台连接与通知
- [ ] 锁屏 / 息屏语音交互
- [ ] PWA 保底方案 (短期替代)
-
-## 交互模式
-
-APP 有两种界面呈现方式，根据启动来源自动切换：
-
-| 启动方式 | 界面模式 | 说明 |
-|---------|---------|------|
-| 桌面图标 / 最近任务 | **全屏 Activity** | 常规 APP 模式，完整功能入口 |
-| 语音唤醒 / 长按 Home / 侧滑 / 长按电源键 / 耳机按键 | **悬浮窗 (VoiceInteractionSession)** | 全屏覆盖层，半透明背景透出底层 APP，不影响当前任务栈 |
-
-悬浮窗模式的要点：
- 借助 `VoiceInteractionSession` 系统窗口，不压入 Activity 返回栈
- 对话结束后窗口收起，用户回到触发前的界面
- 底层 APP 内容半透明可见（模糊遮罩），让用户保持上下文感知
- 窗口高度自适应对话内容，类似 Google Assistant 的卡片式覆盖
-
-## 设计规范
-
- **设计语言**：Material Design 3 (Material You)
- **主题**：动态配色（Dynamic Color），跟随系统壁纸或手动选择主题色
- **暗黑模式**：支持 Light / Dark 双主题，跟随系统或手动切换
- **组件**：全面使用 `androidx.compose.material3` 组件库
- **图标**：Material Icons + 自定义图标
- **动效**：遵循 MD3 动效规范（过渡动画、涟漪效果、Shared Elements）
- **字体**：系统默认字体（Roboto / Google Sans），支持动态字体缩放
-

-
-## 环境要求
-
- Android Studio Hedgehog (2023.1.1) 或更高版本
- Kotlin 2.0+
- JDK 17+
- Android SDK (target: 34+, min: 26+)
-
-## 网络配置（中国大陆用户）
-
-Gradle、Google Maven、Maven Central 等服务器在国内访问缓慢或不可达，首次同步前需配置镜像。
-
-### Gradle Wrapper
-
-`gradle/wrapper/gradle-wrapper.properties`：
-
-```properties
-# 将 services.gradle.org 替换为腾讯/阿里镜像
-distributionUrl=https\://mirrors.cloud.tencent.com/gradle/gradle-8.7-bin.zip
-# 或阿里: https\://mirrors.aliyun.com/macports/distfiles/gradle/gradle-8.7-bin.zip
-```
-
-### 仓库镜像
-
-`settings.gradle.kts` 顶部添加：
-
-```kotlin
-pluginManagement {
-    repositories {
-        maven { url = uri("https://mirrors.cloud.tencent.com/gradle/plugins") }
-        maven { url = uri("https://mirrors.tencent.com/nexus/repository/maven-public") }
-        google()
-        mavenCentral()
-        gradlePluginPortal()
-    }
-}
-dependencyResolutionManagement {
-    repositoriesMode.set(RepositoriesMode.FAIL_ON_PROJECT_REPOS)
-    repositories {
-        maven { url = uri("https://mirrors.tencent.com/nexus/repository/maven-public") }
-        google()
-        mavenCentral()
-    }
-}
-```
-
-### Gradle 属性
-
-`gradle.properties`：
-
-```properties
-# HTTP 代理（如使用 Clash/V2Ray，通常不需要）
-# systemProp.http.proxyHost=127.0.0.1
-# systemProp.http.proxyPort=7890
-# systemProp.https.proxyHost=127.0.0.1
-# systemProp.https.proxyPort=7890
-```
-
-### Android SDK Proxy
-
-若 Android SDK Manager 也下载缓慢，可在 Android Studio 中设置：
-**Settings → Appearance & Behavior → System Settings → HTTP Proxy**
-
-配置为 `mirrors.cloud.tencent.com` 或 `mirrors.neusoft.edu.cn`，端口 `80`。
-
-## 快速开始
-
-> 项目尚未包含可构建的源码，以下为后续开发的参考步骤。
-
-1. 用 Android Studio 打开 `android/` 目录
-2. 按上述"网络配置"替换国内镜像
-3. 等待 Gradle 同步完成
-4. 启动主项目后端服务（参考[主项目 README](../README.md)）
-5. 在 `local.properties` 中配置 `baseUrl` 指向 Gateway 地址
-6. 选择模拟器或设备，点击 Run

+ * 「分享到 App」的接收入口（`ACTION_SEND` / `ACTION_SEND_MULTIPLE`）。

+ * 分享进来时可能还没登录、ChatScreen 甚至还没被组合出来，而登录之后消费它的又是**另一个**
+ * Compose 实例。内容因此必须待在一个不属于任何 UI / ViewModel 的地方——见
+ * [PendingShareHolder]。不塞进 `AppContainer` 是因为那个文件同时被别的并行改动占用，
+ * 这里没有任何依赖需要它：本对象只需要一个 `Context`（读 URI、写 cache）。
+ *
+ * ## 图片为什么在收到的那一刻就落盘
+ * `content://` 的读授权只给到**接收它的那个 Activity / 任务**，登录（可能十几秒、还可能切页）
+ * 之后再去读，拿到的多半是 `SecurityException` / 打不开。所以字节在这里立刻拷进 `cacheDir`，
+ * 之后一律用本端自己的 `file://` 路径——**外部 Uri 只在这个方法里出现一次**。
+ *
+ * ## 清理
+ * 缓存副本只对**产生它的那个进程**有意义（持有者在内存里，进程没了就没人认领），所以
+ * 进程启动时整目录删一次（[reset]）。运行期间不做细粒度回收：那些文件在发送失败被回滚到
+ * 输入框之后**仍然要用**（用户可能过一会儿才点发送），提前删掉就会让预览变空图。
+ * 目录因此以「一次进程生命周期内的分享次数 × 4」为界，另有系统的 cache 回收兜底。

+ *
+ * ## 线程模型
+ * 全部逻辑跑在**调用方线程**上（OkHttp 的调用线程 / WS 重连协程），用 JVM 监视器锁串行化。
+ * 因此这里没有、也不能用协程 `Mutex`——调用点根本没有 suspend 上下文。
