kivy

问题 I am currently developing an app for Android, and I would like to make it so that when the user clicks on a button within the app, they are redirected to the default Android clock app, where they can set up reminders for themselves. Is there any way that Kivy can access those default apps? 回答1: You probably need to construct an appropriate intent, as described at e.g. Intent to launch the clock application on android , but you can do this from Python via pyjnius instead of by writing java

AttributeError: 'NoneType' object has no attribute 'bind' File "/usr/local/lib/python2.7/dist-packages/kivy/lang/builder

问题 I already did buildozer android debug and have the .apk file installed and works fine, at least tested for one/two devices. This is also with the semi-default buildozer.spec , for example : the domain name is still org.test but with the name of the app is adjusted. With this .apk file (after buildozer android debug process), is this the one that is ready to be uploaded to playstore? or there is still some other (technical) preparations? I know that we may do beta test first before making it
