文件“kivy/core/window/_window_sdl2.pyx”，第582行，在kivy.core.window._window_sdl2._WindowSDL2Storage.show_键盘中

Question

我使用kivy开发了这个应用程序。这是在我的windows上运行的完整应用程序，正如你所知，kivy支持CrossPlatform，所以我尝试使用推土机创建apk文件。我已经编辑了规范文件，在此过程中没有发现任何问题，但当我的手机上安装应用程序时，它崩溃了，日志文件中出现以下错误：

File "kivy/core/window/_window_sdl2.pyx", line 582, in kivy.core.window._window_sdl2._WindowSDL2Storage.show_keyboard
