+# Android WebView 壳应用（指向 https://agent.cyjai.com）
+
+这个目录是一个最小可用的 Android APK 壳工程：
+- 后端仍运行在你的服务器
+- APK 只承载 WebView 前端
+
+## 1) 打开工程
+
+Android Studio -> Open -> 选择 `android-webview-app`。
+
+首次打开会自动下载 Gradle 依赖（需要联网）。
+
+## 2) 可改项
+
+- 包名：`app/build.gradle.kts` 与 `MainActivity.kt` 的 `package`
+- 应用名：`app/src/main/res/values/strings.xml`
+- 首页地址：`MainActivity.kt` 中 `HOME_URL`
+
+## 3) 调试打包
+
+- 连接手机/模拟器后，点击 Run
+- 生成 release APK：
+  - Build -> Generate Signed Bundle / APK -> APK
+  - 选择/创建 keystore 后生成
+
+## 4) 已处理能力
+
+- JS / DOM Storage 已开启
+- Cookie 已开启
+- 文件上传 (`<input type=file>`) 已支持
+- 物理返回键支持网页回退
+
+## 5) Nginx 建议（你当前配置基本可用）
+
+你目前 `agent.cyjai.com` 配置已经能支持此壳应用。
+如后续出现 WebSocket 不稳定，可把 `Connection 'upgrade'` 改为官方 map 写法（按 upgrade 条件设置）。

+#   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.
