onCreate在设置了单顶启动模式的情况下运行了2次

问题：

My Launching Activity creatively named LoadingActivity's onCreate method is called 2 times.

清单内容：

<manifest>
    <application>
        ...
        <activity
            android:launchMode="singleTop"
            android:name="com.awesome.app.activites.LoadingActivity"
            android:screenOrientation="portrait">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
        ...
    </application>
</manifest>

First onCreate call is called with Bundle savedInstanceState which is null, shortly after which the onCreate method is called again, but this time with Bundle savedInstanceState which contains the following serialized content:

Bundle[{com.google.app_measurement.screen_service=Bundle[{referrer_name=LoadingActivity, id=1612091517631091562, name=null}], android:viewHierarchyState=Bundle[{android:views={16908290=android.view.AbsSavedState$1@a24446f, 2131296302=android.view.AbsSavedState$1@a24446f, 2131296313=android.view.AbsSavedState$1@a24446f, 2131296424=android.view.AbsSavedState$1@a24446f, 2131296445=android.widget.ProgressBar$SavedState@b25257c, 2131296581=android.view.AbsSavedState$1@a24446f, 2131296582=android.view.AbsSavedState$1@a24446f}}], androidx.lifecycle.BundlableSavedStateRegistry.key=Bundle[{}], android:lastAutofillId=1073741823, android:fragments=android.app.FragmentManagerState@a24ee05}]

是的，这并不意味着什么，但这可能与帖子底部的内容有关。

尝试过：

I have tried setting launchmode settings with android:launchMode="singleTop" for the LoadingActivty in my AndroidManifest.xml, but this does not help at all, it still runs the onCreate 2 times.

我已经遍历了onCreate方法，没有再在哪里onCreate或更改ApplicationContext设置，即方向（以物理方式或程序方式）等。

任何想法为什么会发生这种情况以及我可以采取什么措施来解决。

为了它的价值，我最近更新了我的部门并在清单中看到了这一点：

它使用纵向启动模式进行编译（出于过时的原因更改软件包名称），但是我认为这可能与两次启动有关
