+# CI / 本地共用: 修复 Android 软键盘遮挡输入框
+# 在 `tauri android init` 之后、`tauri android build` 之前运行。
+#
+# 背景:
+#   Tauri 2 生成的 MainActivity 调用 enableEdgeToEdge(), 且不处理 IME Insets。
+#   Android 15+ (targetSdk 35+) 强制 edge-to-edge 后, 系统不再因软键盘缩小窗口,
+#   清单里的 adjustResize 也随之失效 → 键盘直接盖住 WebView, 底部弹层输入框被遮挡。
+#
+# 做法:
+#   1. AndroidManifest.xml 的 MainActivity 补 windowSoftInputMode="adjustResize"
+#      (兼容 API < 35 的旧行为)
+#   2. 重写 MainActivity.kt: 监听 WindowInsetsCompat.Type.ime(), 键盘可见时
+#      把 IME 高度作为底部内边距加给内容容器 (等价恢复旧版 adjustResize),
+#      这样 WebView 真正变矮, 所有 position:fixed / bottom:0 的弹层自动上移。
+#
+# 幂等: 重复执行不会重复注入。
+# 注意: gen/android 被 gitignore, CI 每次 init 都重新生成, 所以每次构建都要跑本脚本。
