Start with docs/mvvm/AsyncRelayCommand.md, linked from the issue, and review the section describing NotifyCanExecuteChanged(). Document the Android main-thread requirement and verify that the guidance clearly tells readers when this call must be made. Done means the article covers the reported crash scenario without changing the toolkit implementation.
