Allow to exit from fullscreen with the back button in ExoPlayer

[timm0e]

When using ExoPlayer, this allows users to exit the full-screen mode by pressing the back button, similar to e.g. the YouTube app.

Sounds reasonable. Thanks for the contribution!

Im not sure if this was the change but now when i use back gesture it goes to portrait mode from landscape mode instead of actually leaving fullscreen @Maxr1998

Yes, that's how it's supposed to work. You switch from landscape to portrait and leave fullscreen at the same time. It's the same that happens when pressing the fullscreen switcher in the UI.
While in landscape, the player will always be in fullscreen to not overlap the video, especially since we don't show any other content there.
In portrait mode, the player won't enable fullscreen, because the video size is limited by the horizontal width there and not the system bars. In the future, we might show more data best to the video, like next up or cast, to fill the empty area with useful information.
The only exception is portrait video, where you can enter and exit fullscreen while staying in potrait mode.

i dont mean to be offensive, but this is pretty useless behavior forcing you to take 2 actions if you want to close the player, no matter what. its actually horrible cause after leaving landscape you have to move your finger to a different edge to be able to back gesture.

i dont see how it could ever be useful, if i want to close the player i want to do just that. if i want extra options/info i will tap the screen. its pretty standard behavior on every app and player that ive used.

at least give an option to disable it or have it disabled when "start landscape mode" is enabled.

i dont think i can emphasize enough how much of a pain it is to have to gesture back twice every time i need to close the player, it doesnt even pause it. if i wanted to go to portrait mode i would press "exit full screen" icon that is there for a reason.

Is there an option to disable this? Can one be added?

I expect the bottom back button to do the same thing as the back button at the top but it doesn't.

[elnoelsi]

There is no option thats the most annoying part of all, i genuinely think you have to be masochist to enjoy this feature in any way

Please open an issue so we can discuss this change. If there is a high demand for a revert/preference we may consider it.
