从Chrome启动活动时出现运行时异常

Question

我已配置我的应用程序中的一项活动，可以使用如下所示的深层链接将其打开：

<activity
        android:name=".ui.barcodescanner.BarcodeScannerActivity"
        android:label="@string/app_name">
        <intent-filter>
            <action android:name="android.intent.action.VIEW" />
            <category android:name="android.intent.category.DEFAULT" />
            <category android:name="android.intent.category.BROWSABLE" />
            <data
                android:host="com.company"
                android:scheme="http"
                android:pathPrefix="/myapp"/>
        </intent-filter>
    </activity>

当chrome在API 27 Pixel 2 XL仿真器上重定向到http://com.mycompany/myap时，此操作可以正常工作（我的应用程序以正确的活动启动）。但是，当我在API 29 OnePlus 6上运行它时，出现以下错误：

java.lang.RuntimeException: Unable to start activity ComponentInfo{com.company.android.myapp/com.company.android.myapp.ui.login.IONLoginActivity}: android.util.AndroidRuntimeException: Calling startActivity() from outside of an Activity  context requires the FLAG_ACTIVITY_NEW_TASK flag. Is this really what you want?

这是为什么？
