Kivy .kv File Won't Read

I have just started learning to program. I have a really basic App based on a pong game tutorial on the kivy.org website, but I must have a basic flaw that I can't see, because whe

Solution 1:

• Check whether your MainApp(App) class name is same as your .kv file name without the 'App' (if not, make them the same). It's not case sensitive. For example: MaNagerApp(App) will load manager.kv.

OR

• If you don't want to change name then simply add self.load_kv(your_kv_file_name), like this:

  def build(self):
      self.load_kv('singularity.kv')
      return Singularity()
  

Solution 2:

The name of the file "name.kv" should be in lowercase

Solution 3:

Make your .kv file name as same as main Class name ex:

class galaxyApp(App): # this is your main class
    pass
galaxyApp().run()

make your .kv file name same as main class name (not case sensitive). In my case my .kv file name will be "galaxy.kv"
