启用代码混淆后Wear OS Tile崩溃：LifecycleRegistry的LifecycleOwner已被回收

我开发了一款简单的Wear OS应用，包含一个Tile，点击Tile可打开自定义应用列表。Tile使用androidx.glance:glance-wear-tiles:1.0.0-alpha05，应用其余部分基于androidx.wear.compose开发。禁用代码混淆时一切功能正常，但启用代码混淆后，通过Tile启动Activity会导致应用崩溃，从系统应用启动器启动Activity则无此问题。

解决方案 #

这个问题是代码混淆导致Glance Tile相关的Lifecycle类被错误混淆，进而引发生命周期管理异常。需要在混淆规则文件（proguard-rules.pro）中添加以下规则，保护Glance和相关Lifecycle组件不被混淆：

# 保护Glance Wear Tile相关类
-keep class androidx.glance.** { *; }
-keep class androidx.glance.wear.tiles.** { *; }

# 保护Lifecycle相关组件，避免生命周期所有者被混淆
-keep class androidx.lifecycle.** { *; }
-keep class androidx.lifecycle.LifecycleOwner { *; }
-keep class androidx.lifecycle.LifecycleRegistry { *; }

# 保护你的Tile服务类和Activity不被混淆
-keep class nodomain.pacjo.wear.anotherapplist.tile.LauncherTileService { *; }
-keep class nodomain.pacjo.wear.anotherapplist.presentation.MainActivity { *; }

补充说明 #

• 混淆时Glance框架依赖的反射和生命周期相关类被重命名或移除，导致Tile服务在停止时无法正确处理生命周期状态，最终触发崩溃。
• 保留Tile服务和目标Activity的完整类名，确保actionStartActivity能正确找到对应的组件。
