If the width or height is greater than 8191, left-shifting causes the sign bit to be lost, turning a '1' into a '0', which results in an incorrect width or height.
I agree there's a bug here, but I'm not sure this is quite a precise description of the problem. A quick experiment suggests that the left shift (<<) works fine (if we are just looking at bits), but the right shift (>>) is where the problem is introduced, because >> does "sign extension" in Java - meaning if input value is negative (the MSB of the 32-bit int is 1), then the result will be negative too. This can be fixed by using the unsigned right shift operator (>>>).
You can see this in jshell:
$ jshell

Description
Version used: 1.0.0-alpha02
Devices/Android versions reproduced on: Emulator API 28, Samsung J5 API 25
Sample project attached.
I'm trying to create a custom Navigator and custom NavDestination that would animate ConstraintLayout (but any custom NavDestination would cause this issue).
Intended behaviour is shown in attached video: Layout_animations.webm
However, when I rotate the screen, while the navigation is on the custom destination, the application crashes.
The crash is caused by an unknown destination, which can only be added after custom navigator.
If I add custom destination in nav_main.xml, the app will also crash, because the navigator is not yet added.
This issue could be fixed by extending NavHostFragment, but I would need to override the whole onCreate() method.
I would need to add my custom navigator right after the line:
mNavController = new NavController(context);
I can think of 2 possible solutions in the library:
1. Delegate creating of NavController, so that a custom NavController can be provided in the XML layout file.
2. Call a new protected method "NavHostFragment.onNavControllerCreated(NavController)" right after the NavController is created, that could be overridden in a custom NavHostFragment, before the graph is created.
If there is any solution to my problem that I didn't think of, please provide a more exhaustive example in the documentation:
