在我的情况下，我通过验证所有导航操作都正确地管理到各自的图形中，并更新了设备后退按钮的代码来解决这个问题，如下所示:

 onBackPressedDispatcher.addCallback(this /* lifecycle owner */, object : OnBackPressedCallback(true) {
        override fun handleOnBackPressed() {
            // Back is pressed... Finishing the activity
            if (navHostFragment.childFragmentManager.backStackEntryCount == 0) {
                // First fragment is open, backstack is empty
               finish()
            } else {
                navHostFragment.navController.popBackStack()
            }
        }
    })

在我的例子中，我使用了一个自定义的后退按钮来向上导航。我调用了onBackPressed()而不是下面的代码

findNavController(R.id.navigation_host_fragment).navigateUp()

这导致发生IllegalArgumentException。在我将其更改为使用navigateUp()方法之后，我就不会再次崩溃了。

I caught this exception after some renames of classes. For example: I had classes called FragmentA with @+is/fragment_a in navigation graph and FragmentB with @+id/fragment_b. Then I deleted FragmentA and renamed FragmentB to FragmentA. So after that node of FragmentA still stayed in navigation graph, and android:name of FragmentB's node was renamed path.to.FragmentA. I had two nodes with the same android:name and different android:id, and the action I needed were defined on node of removed class.

I am calling the 2.3.1 Navigation and the same error occurs when the application configuration changes. When the cause of the problem was found through Debug, the GaphId in NavHostFragment did not take effect as the ID currently set by calling navController.setGraph(). The GraphId of NavHostFragment can only be obtained from the <androidx.fragment.app.FragmentContainerView/> tag. At this time, this problem will occur if there are multiple GraphIds dynamically set in your code. When the interface is restored, the Destination cannot be found in the cached GraphId. You can solve this problem by manually specifying the value of mGraphId in NavHostFragment through reflection when switching Graph.

navController.setGraph(R.navigation.home_book_navigation);
try {
    Field graphIdField = hostFragment.getClass().getDeclaredField("mGraphId");
    graphIdField.setAccessible(true);
    graphIdField.set(navHostFragment, R.navigation.home_book_navigation);
} catch (NoSuchFieldException | IllegalAccessException e) {
    e.printStackTrace();
}

这发生在我身上，我的问题是我在标签项片段上单击FAB。我试图从一个标签项片段导航到另一个片段。

但是根据Ian Lake的回答，我们必须使用tablayout和viewpager，没有导航组件支持。因此，没有从包含片段的标签布局到标签项片段的导航路径。

ex:

containing fragment -> tab layout fragment -> tab item fragment -> another fragment

解决方案是创建一个从包含片段的标签布局到预期片段的路径 例如:path: container fragment ->另一个片段

劣势:

导航图不再准确地代表用户流。
