Pyjnius: ' 뷰 계층 구조를 만든 원래 스레드만 해당 뷰를 만질 수 있습니다.' android.view.Window 메서드에 액세스하려고 할 때 오류가 발생했습니다.

from kivy.app import App
from kivy.uix.relativelayout import RelativeLayout
from jnius import autoclass

CurrentActivity  = autoclass('org.kivy.android.PythonActivity').mActivity
view = CurrentActivity.getWindow().getDecorView()
view.setKeepScreenOn(True)

class Root(RelativeLayout):
    def __init__(self):
        super().__init__()

SomeApp().run()

android.view.Window 의 다른 방법을 사용할 때도 동일한 오류가 발생합니다.

CurrentActivity  = autoclass('org.kivy.android.PythonActivity').mActivity
WindowManager = autoclass('android.view.WindowManager$LayoutParams')
CurrentActivity.getWindow().addFlags(WindowManager.FLAG_KEEP_SCREEN_ON)
