C# Xamarin Android'；App&x27；已经停止（牛轧糖）

在应用程序的生命周期内，我们收到消息“App”已停止。当前所有方法都有try和catch子句，但是我们无法捕获此未处理的异常。 我们已尽一切努力，找不到罪魁祸首。我们已经设法获得了应用程序的android日志，所以有人能告诉我们问题可能是什么吗

最好的做法是检查您进行JNI调用的地方，并检查您是否在完成引用后删除了它们

如果您没有进行JNI调用，那么很可能您正在保留不再需要的引用。请注意嵌套引用，这些引用永远不会被垃圾收集，并且会在应用程序的整个生命周期内累积，直到您遇到操作系统级别的异常。
非常感谢您的帮助，我们将对此进行调查。你能举一个可能导致这种情况的JNI调用的例子吗？另外，嵌套引用是指来自嵌套类的引用吗？任何存储来自JNI的值的东西，但是，如果您需要问这个问题，您很可能在任何情况下都不会进行本机调用。对于嵌套引用，我指的是保留对类的引用的类，而这些类反过来又保留引用。垃圾收集器永远无法释放它们，因为整个链都保持着彼此之间的链接。
