It works, but there is a serious problem...

[codthing]

I tried to configure the deep link in your way, the same as yours. I can use deep links.
But here comes the point. When I open the app without using the deep link, if I open the app manually normally, when I click the android back button, the app will exit directly.

I tried to cancel the linking and then package again, and my app resumed to work correctly.
If linking is added again and then packaged, the above error will occur.

I want to know whether the configuration in deepLinking is related to the configuration in Stack? Will there be a conflict?

Use android:launchMode= "singleTask" inside < activity/>

This issue has been in the past for a long time, the method I use is to monitor goback on each screen
