android - 对接时应用程序严重崩溃

每当平板电脑与底座连接或断开连接时，我的 Xamarin Android 应用程序就会崩溃，我不知道从哪里开始。

  • 通讯座只有电源，根本没有 USB 连接。
  • 通过 USB 连接平板电脑时不会崩溃。
  • 平板电脑上的其他应用都没有同样的问题。

我尝试使用

阻止应用切换到“汽车”模式 
        UiModeManager amanger = (UiModeManager)Application.Context.GetSystemService(Context.UiModeService);
        amanger?.DisableCarMode(DisableCarModeFlags.None);

但这并没有帮助。

调试输出显示:

(顺便说一句:Thread finished: UdpReceiveThread #11 是因为在 Dispose 中我们清理了套接字.. 所以它不是应用程序崩溃的结果。)

LogCat 没有向我显示很多有趣的信息:

关于我可以在哪里寻找的任何线索？

最佳答案

通过添加“ConfigurationChanges = ConfigChanges.UiMode”修复它

到主要 Activity 参数:

[Activity(Label = "View for MainActivityView", LaunchMode = LaunchMode.SingleTop, ScreenOrientation = ScreenOrientation.SensorLandscape, ConfigurationChanges = ConfigChanges.UiMode)]

通过调查更多关于 onReceive: android.intent.action.CONFIGURATION_CHANGED

在日志中，查找有关配置更改的信息，并找到一条注释，表示收到后 Activity 会重新启动是正常的。

参数 ConfigurationChanges = ConfigChanges.UiMode 要么停止将这些事件传递到我的应用程序，要么停止正确处理这些事件。我不确定，但它现在稳定了。
