// Flag LayoutParams.FLAG_TURN_SCREEN_ON was deprecated in O_MR1, but calling the new API
// setTurnScreenOn(true) doesn't give us the expected behavior.
//
// Calling setTurnScreenOn(true) alone doesn't turn on the screen when the device is locked.
// We must also call KeyguardManager#requestDismissKeyguard, which will bring up the lock
// screen for the user to enter their credentials.
//
// If the Keyguard is not secure or the device is currently in a trusted state, calling
// requestDismissKeyguard will immediately dismiss the Keyguard without any user interaction.
// However, the lock screen will still pop up before it quickly disappears.
//
// If the Keyguard is secure and the device is not in a trusted state, the device will show
// the lock screen and wait for the user's credentials.
//
// Therefore, to avoid showing the lock screen, we will continue using the deprecated flag in
// O_MR1 and later Android versions.
//
// Flag LayoutParams.FLAG_SHOW_WHEN_LOCKED was also deprecated in O_MR1, and the new API
// setShowWhenLocked(boolean) works. However, as the purpose of the two new APIs is to prevent
// an unintentional double life-cycle event, only using one is ineffective.
//
// Therefore, to simplify code and make testing easier, we will also keep using
// LayoutParams.FLAG_SHOW_WHEN_LOCKED.
