屏幕解锁后 Android 上的 Kivy 应用程序变黑

Question

主 App class 的 on_pause() 和 on_resume() 方法已实现如下：

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

    def on_pause(self):
        return True

    def on_resume(self):
        pass

Logcat output 与应用相关的从屏幕锁定到解锁

奇怪的是，应用程序在打开通知托盘并再次关闭后恢复正常。

版本信息

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

对此的任何帮助将不胜感激！
