Got a SIGABRT while executing native code. This usually indicates
a fatal error in the mono runtime or one of the native libraries 
used by your application.

我尝试将代码包装在 try catch 中，但仍然遇到崩溃。知道可能是什么问题吗？

Answer 1

我找到了解决方案，以防其他人遇到同样的问题。您需要将 [隐私 - 麦克风使用说明] 属性添加到 info.list 中并附上文本说明，以便应用程序会要求您允许访问使用麦克风。
