C# Java.Lang.RuntimeException:在S7 mobile上

我在xamarin.android应用程序中尝试长按编辑器控件时遇到以下异常。此问题发生在三星S7上，其操作系统为Verison 7.0

未处理的异常：Java.Lang.RuntimeException:尝试调用 虚拟方法的布尔 android.widget.Editor$selectionModifiercorController.isDragAcceleratorActive（） 在空对象引用上发生错误

下面是异常的堆栈跟踪

java.lang.NullPointerException: Attempt to invoke virtual method 'boolean android.widget.Editor$SelectionModifierCursorController.isDragAcceleratorActive()' on a null object reference

我们正在动态创建编辑器控件

这个问题不会发生在任何其他设备上
