排查无障碍相关的IndexOutOfBoundsException神秘崩溃问题

我正在排查应用分析工具上报的崩溃，堆栈信息如下：

这个堆栈完全没有指向我的业务代码，我在多台设备上测试都无法复现。崩溃看起来和无障碍功能相关，但我只遵循了常规无障碍开发规范，没有做过特殊处理。想请教可能的排查方向。

更新 [2025-08-24]

我已经确认崩溃发生在应用Activity退出后，通过添加标记跟踪Activity状态得知。该崩溃由Thread.UncaughtExceptionHandler捕获，我认为这是系统bug，没有实际危害。

排查方向建议 #

• 升级Material Components库：崩溃发生在NavigationMenuPresenter的内部适配器中，很可能是旧版本库存在无障碍场景下的线程安全或生命周期兼容问题，尝试升级到最新稳定版的Material库，看官方是否已经修复该问题。
• 检查Activity销毁时的菜单数据操作：排查Activity退出过程中，是否有异步线程在修改导航菜单的数据源（比如onDestroy之后仍有网络回调更新菜单列表），导致无障碍服务访问时列表长度已经变化，引发索引越界。
• 模拟无障碍场景测试：开启TalkBack、屏幕阅读器等无障碍服务后，快速执行Activity退出操作（比如连续按返回键），高频触发场景下可能复现崩溃，因为无障碍框架的回调可能在Activity生命周期后期仍在执行。
• 过滤全局异常上报：既然确认崩溃发生在Activity退出后且无实际影响，可以在全局异常处理器中添加过滤规则，忽略这类来自Material内部且发生在Activity销毁后的崩溃，避免干扰统计数据。
• 统计系统版本分布：查看崩溃上报的设备系统版本，看是否集中在特定Android版本（比如Android 11/12），部分系统版本的无障碍框架可能存在兼容性bug，针对性测试该版本设备。
