Android : E/InputDispatcher: Window handle drag has no registered input channel

In my app, I am dragging a customView on the screen and based on the location of the finger, I update certain arrangement of other views. I keep getting this error in my Logcat. Few seconds after the drag is in progress, the parent view gets all dark and doesn't get updated. I also keep seeing this error:

 E/InputDispatcher: Window handle drag has no registered input channel

But the app does respond - not totally irresponsive. Any ideas on how to solve it? sorry, I am not able to share code as it is part of huge module and it is hard to make it small to show it here.

Since you did not share code, it is hard to give an answer that fits your use case.
I was hiding the soft keyboard programmicaly and got the same error:

2022-03-19 15:57:13.674 2069-3576/system_process E/InputDispatcher: Window handle Window{5f5b041 u0 app.ui.activities.LoginActivity} has no registered input channel

I solved it by changing the InputMethodManager "." hideSoftInputFromWindow method first "windowToken" argument
FROM: view.getWindowToken() or view.windowToken

TO: view.applicationWindowToken which removed the logcat error.

I was using the emulator.
