在我的地图片段和任何其他片段之间快速切换时，出现“致命信号11（SIGSEGV）”，应用崩溃了。我已经阅读到此错误与库函数问题有关，并且我猜想它与onConnected（）方法中的函数有关，因此与日志消息有关。感谢您提供有关如何解决此问题的帮助。

好像您在Mapbox中使用Fragment。
将mapView.onDestroy()保留在onDestroyView()的超级调用@ Fragment方法下面，并从mapView.onDestroy() Fragment's方法中取出onDestroy()。按照this issue on github。
也请阅读how it hould be used in fragment。
您的方法将如下所示。
override fun onDestroy() {
locationEngine?.deactivate()
val settings = context?.getSharedPreferences(preferencesFile, Context.MODE_PRIVATE)
val editor = settings?.edit()
editor?.putString("shil", shilview.text.toString())
editor?.putString("dolr", dolrview.text.toString())
editor?.putString("quid", quidview.text.toString())
editor?.putString("peny", shilview.text.toString())
editor?.apply()
super.onDestroy()
//mapView.onDestroy() not required here for Fragment
}
override fun onDestroyView() {
super.onDestroyView()
mapView.onDestroy() //after super call
}
