      // Note:

      //

      // 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.
