I'm developping my first app in Kivy/KivyMD and I've run into the following problem:
I've build my app using buildozer and when I open it on my android phone, the MDDropDownItem opens correctly, but doesn't set the new item (or even closes for that matter) when I tap it. It does work correctly on my desktop.
Relevant code (main.py):
def __init__(self, **kwargs):
super().__init__(**kwargs)
self.screen = Builder.load_string('''
<ContentNavigationDrawer>:
orientation: 'vertical'
padding: "8dp"
spacing: "8dp"

MDList:
OneLineListItem:
text: 'Post Mortem Interval'
on_press:
root.nav_drawer.set_state('close')
root.screen_manager.current = 'Post Mortem Interval'
Screen:
BoxLayout:
orientation: 'vertical'
MDToolbar:
id: toolbar
pos_hint: {'top': 1}
