重新创建 activity 后 super.onCreate(savedInstanceState) 崩溃

Question

我的项目中有两个活动 ActivityOne 和 MainActivity。我使用 ActivityOne 中的意图开始 MainActivity，然后我在 MainActivity 中切换暗模式开关并在 activity 中调用 recreate()。但是 MainActivity 在重新创建时在 super.onCreate(savedInstanceState) 行崩溃。

androidx片段版本：1.2.5

生命周期版本：2.2.0

主要活动：

override fun onCreate(savedInstanceState: Bundle?) {
        val userInterfaceMode = when (UIMode.currentUIMode) {
            is UIMode.DarkMode -> AppCompatDelegate.MODE_NIGHT_YES
            is UIMode.LightMode -> AppCompatDelegate.MODE_NIGHT_NO
            else -> AppCompatDelegate.MODE_NIGHT_FOLLOW_SYSTEM
        }
        AppCompatDelegate.setDefaultNightMode(userInterfaceMode)
        super.onCreate(savedInstanceState)
        setContentView(R.layout.activity_main)
        overridePendingTransition(
            R.anim.enter_activity_fade_in_anim,
            R.anim.enter_activity_fade_out_anim
        )
        if (savedInstanceState == null){
            setupNavigation()
        }
    }

    override fun onRestoreInstanceState(savedInstanceState: Bundle) {
        super.onRestoreInstanceState(savedInstanceState)
        setupNavigation()
    }

    private fun setupNavigation(){
        if (supportFragmentManager.findFragmentByTag(NAV_HOST_TAG) != null){
            val host = supportFragmentManager
                .findFragmentByTag(NAV_HOST_TAG) as NavHostFragment
            supportFragmentManager
                .beginTransaction()
                .attach(host)
                .setPrimaryNavigationFragment(host)
                .commit()
        }else{
            val host = NavHostFragment.create(R.navigation.navigation_graph)
            supportFragmentManager
                .beginTransaction()
                .add(
                    R.id.mainActivityRoot, host,
                    NAV_HOST_TAG
                )
                .setPrimaryNavigationFragment(host)
                .commit()
        }
    }

导航图和目的地使用相同的 ID 似乎是个问题。

我们遇到了非常相似的崩溃，并通过为导航图使用唯一 ID 解决了这个问题。
