+# 车管家 Android 客户端 - 快速开始指南
+
+## 项目概述
+
+这是一个现代化的 Android 应用，为车管家 4S店车辆维保管理系统提供移动端支持。
+
+## 开发前准备
+
+### 1. 安装 Android Studio
+
+下载并安装最新版本的 Android Studio:
+https://developer.android.com/studio
+
+### 2. 配置 JDK
+
+确保安装了 JDK 17 或更高版本：
+```bash
+java -version  # 应该显示 17.x.x 或更高
+```
+
+### 3. 启动后端服务
+
+在运行 Android 应用之前，确保后端服务正在运行：
+
+```bash
+# 进入后端项目目录
+cd car-maintenance-system/backend
+
+# 使用 Maven 启动服务
+mvn spring-boot:run
+
+# 或者在 IDEA 中运行 SpringBootAppApplication.java
+```
+
+后端默认运行在 `http://localhost:8080`
+
+### 4. 配置 API 地址
+
+根据你的测试环境，修改 `app/build.gradle.kts`：
+
+**使用 Android 模拟器：**
+```kotlin
+buildConfigField("String", "API_BASE_URL", "\"http://10.0.2.2:8080/api/\"")
+```
+
+**使用真机：**
+```kotlin
+buildConfigField("String", "API_BASE_URL", "\"http://YOUR_PC_IP:8080/api/\"")
+// 例如: "http://192.168.1.100:8080/api/"
+```
+
+## 运行应用
+
+### 方式一：使用 Android Studio
+
+1. 打开 Android Studio
+2. 选择 **File > Open**
+3. 选择 `car-maintenance-system/android` 目录
+4. 等待 Gradle 同步完成
+5. 点击工具栏的 Run 按钮 (绿色三角形)
+
+### 方式二：使用命令行
+
+```bash
+cd android
+
+# 查看连接的设备
+adb devices
+
+# 安装并运行
+./gradlew installDebug
+```
+
+## 测试账号
+
+| 角色 | 用户名 | 密码 | 功能 |
+|------|--------|------|------|
+| 管理员 | admin | 123456 | 系统管理、数据统计 |
+| 工作人员 | staff001 | 123456 | 工单处理、预约确认 |
+| 客户 | customer001 | 123456 | 查看车辆、预约服务 |
+

+
+## 常见问题
+
+### 1. Gradle 同步失败
+
+**问题**: Gradle 同步时出现错误
+
+**解决方案**:
+```bash
+# 清理项目
+./gradlew clean
+
+# 重新构建
+./gradlew build
+
+# 如果还是失败，删除 .gradle 目录后重试
+rm -rf .gradle
+```
+
+### 2. 网络请求失败
+
+**问题**: 应用无法连接到服务器
+
+**解决方案**:
+- 确认后端服务正在运行
+- 检查 API_BASE_URL 配置
+- 确保设备和电脑在同一网络（真机测试）
+- 检查防火墙设置
+
+### 3. 登录失败
+
+**问题**: 登录时提示错误
+
+**解决方案**:
+- 确认后端数据库中有测试用户
+- 检查用户名和密码是否正确
+- 查看后端日志确认请求是否到达
+
+### 4. 模拟器无法访问宿主机
+
+**问题**: 模拟器中的 App 无法访问电脑上的后端服务
+
+**解决方案**:
+使用 `10.0.2.2` 代替 `localhost`:
+```kotlin
+// 错误
+buildConfigField("String", "API_BASE_URL", "\"http://localhost:8080/api/\"")
+
+// 正确（模拟器）
+buildConfigField("String", "API_BASE_URL", "\"http://10.0.2.2:8080/api/\"")
+```
+
+### 5. 数据显示为空
+
+**问题**: 登录后车辆、工单等数据显示为空
+
+**解决方案**:
+- 确认后端数据库有相关数据
+- 使用 Admin 账号登录后台添加测试数据
+- 检查客户ID是否正确关联
+
+## 调试技巧
+
+### 查看 API 请求
+
+在 `NetworkModule.kt` 中，日志级别已设置为 `BODY`：
+```kotlin
+if (BuildConfig.DEBUG) {
+    HttpLoggingInterceptor.Level.BODY
+}
+```
+
+在 Logcat 中过滤 `OkHttp` 即可看到所有网络请求。
+
+### 查看 Token 存储
+
+在 Logcat 中过滤 `TokenManager` 可以看到 Token 相关的日志。
+
+## 下一步开发
+
+### 功能优先级
+
+1. **高优先级**
+   - 在线预约表单
+   - 车辆详情查看
+   - 工单详情查看
+
+2. **中优先级**
+   - 管理员完整功能
+   - 工作人员功能
+   - 推送通知
+
+3. **低优先级**
+   - 数据刷新机制
+   - 离线缓存
+   - 图片上传
+
+### 扩展功能建议
+
+- [ ] 车辆照片上传
+- [ ] 电子签名
+- [ ] 扫码查看车辆
+- [ ] 消息推送（Firebase）
+- [ ] 支付集成
+- [ ] 数据导出
+- [ ] 多语言支持

+
+### 测试账号
+
+- **管理员**: admin / 123456
+- **工作人员**: staff001 / 123456
+- **客户**: customer001 / 123456
+
+## 构建和运行
+
+### 使用 Android Studio
+
+1. 打开 Android Studio
+2. 选择 `File > Open`，选择 `android` 目录
+3. 等待 Gradle 同步完成
+4. 连接 Android 模拟器或真机
+5. 点击 Run 按钮（或按 Shift+F10）
+
+### 使用命令行
+
+```bash
+# 进入项目目录
+cd android
+
+# 构建 Debug 版本
+./gradlew assembleDebug
+
+# 安装到设备
+./gradlew installDebug
+
+# 或者直接运行
+./gradlew installDebug
+```
+
+## 主要依赖
+
+```kotlin
+// Compose BOM
+implementation(platform("androidx.compose:compose-bom:2023.10.01"))
+
+// Hilt
+implementation("com.google.dagger:hilt-android:2.48")
+
+// Retrofit
+implementation("com.squareup.retrofit2:retrofit:2.9.0")

+Remote Data Source (API)
+```
+
+### 数据流
+```
+UI Screen
+    ↓ (用户操作)
+ViewModel
+    ↓ (调用方法)
+Repository
+    ↓ (网络请求)
+API Service
+    ↓ (返回数据)
+Repository (处理数据)
+    ↓ (StateFlow)
+ViewModel (状态更新)
+    ↓ (collectAsState)
+UI Screen (自动更新)
+```
+

+#   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
+#       within the Gradle project.
