Xamarin Forms App 在启动时与 One Plus 5t 崩溃

Question

我找不到启动崩溃的原因。我的一加5t就出现了运行Android8，其他设备不知道
目标 api：26（我也试过将其设置为 23）
最小值：15（我也尝试将其设置为 23）
链接：none
设备：一加5t

这是堆栈跟踪：

未处理的异常：

Java.Lang.NullPointerException: Attempt to invoke virtual method 'void android.view.View.setTranslationZ(float)' on a null object reference

Answer 1

void android.view.View.setTranslationZ(float)

某些 nuget 包在某些特定设备上使用的代码不是运行。卸载未使用的软件包问题消失了
