Description of the changes in your PR

This fixes the half overlaying cutout on devices with API version 28 and higher. Currently, there are undesirable black bars.

This also respects the cutout when rotating the phone and resizes the video accordingly when in fullscreen. At the moment this leaves undesirable black bars at the top and bottom on devices that have a cutout and a screen that is nearly or exactly the resolution of the video. Maybe a setting can help here or a check for video/device resolution. Let me know what behavior you prefer.

This is my first encounter with Android in about 7 years, so please go easy on me. Let me know if there are bad behaviors or APIs that I missed.

Thank you for the PR!

I checked if the problem exists on my device (Android 9; Huawei EMUI 9.1.0) and I'm unable to reproduce it in the first place.
Does this only happen on specific devices/Android versions?

[Cheechaii]

I have seen this problem on hardware on a Nokia 7.2 with Android 10 (API 29) and can reproduce this in the emulator for the virtual device definition "Pixel 3 XL" with API lvl 30 (which is in the screenshots) and also when I create a custom device with API lvl 30 resolution 1920x1080 plus enabling the cutout setting in the developer tools.

Maybe the author of the original issue #5787, @desmonk can tell us their device.

@Cheechaii the code seems to be duplicated between two difference places; can you de-duplicate it?

[litetex]

I'm also pretty sure that the code can be shrunk with the "?:" aka ternary operator

[Cheechaii]

I extracted the code and replaced 3 code duplications and used the ternary expression.

looks good to me. Thank you!

I think we should revert this PR as it causes multiple problems:

• Notch not filled in full screen mode #7915 - Fails to fill the notch correctly
• Player UI hidden during portrait mode playback #7912 - Fails to align the system menu properly
