屏幕解鎖后 Android 上的 Kivy 應用程序變黑

Question

主 App class 的 on_pause() 和 on_resume() 方法已實現如下：

class FitnessApp(App):
    def build(self):
        return RootWidget()

    def on_pause(self):
        return True

    def on_resume(self):
        pass

Logcat output 與應用相關的從屏幕鎖定到解鎖

奇怪的是，應用程序在打開通知托盤並再次關閉后恢復正常。

版本信息

1. Android 10 QKQ1
2. Python 3.7.6
3. Kivy 1.11.1
4. 構建器 1.2.0

對此的任何幫助將不勝感激！
