问题 As the title says, I've made an .apk to run on my Android mobile. It runs perfectly on PC. As soon as I take out all SymPy commands, it runs on Android too. I've mentioned the "sympy" in the buildozer.spec file, and it's not giving any errors. But as soon, as the loading on my Android-screen is over, the App disappears. Does anyone know, if I have to do more, than mentioning the sympy in the .specs file? ADB-Logcat: "ImportError: No module named unittest" I don't know, what "unittest" ist,

问题 Kivy documentation states that "Touching the spinner displays a dropdown menu with all the other available values from which the user can select a new one." Is there any workaround to tell if it is an old value a user selected in order to perform the same action? I am really stuck with this, please help me out. 回答1: Rather than using the on_text or on_select , you can use the Buttons that make up the DropDown to trigger whatever method you want to run.
