研究方向

Start at app.file_chooser() and trace the selected(selection) callback when the Kivy file chooser is cancelled versus when a file is selected. Review the Firebase Storage upload path and the stated Windows and Android context; done means cancellation no longer raises an error and the selected-file upload behavior is understood on the supported platform.
