WearOS应用Compose旋转事件分发崩溃问题咨询

这是Compose焦点系统内部状态不一致引发的致命崩溃，触发时机是用户操作旋转表冠（Rotary事件）时，焦点系统处于已失效状态，属于框架内部逻辑问题，但会直接导致应用崩溃。

是否需要关注？ #

• 必须关注，优先级中等
  • 这是致命异常（Fatal Exception），会直接导致应用闪退，严重影响用户体验，用户会将崩溃责任归于你的应用，而非Compose框架。
  • 虽然不是业务代码触发，但用户的正常操作（旋转表冠）会触发该崩溃，覆盖的用户群体是使用带旋转表冠的WearOS设备用户，不可忽视。

处理建议 #

• 优先升级Compose依赖：这类框架内部崩溃通常在后续版本中会被修复，检查当前使用的androidx.compose.ui:ui等相关依赖版本，升级到最新稳定版。
• 临时规避（谨慎使用）：如果暂时无法升级，可以尝试在Rotary事件处理相关逻辑外层添加try-catch，捕获IllegalStateException，避免应用崩溃，但需注意这可能掩盖焦点系统的其他状态问题。
• 收集崩溃上下文：查看Crashlytics中的崩溃设备型号、WearOS版本、用户操作路径，确认是否是特定设备或系统版本触发，辅助定位问题。
