[Gear VR] Back button handling - how ?

There's how to in the Unreal Documents.

You need to set 'gearvr.HandleBackButton' console variable to 1 (either in ConsoleVariables.ini or in [SystemSettings] section of ...Engine.ini (Base... or Default...).

And then follow the official docs ?

If you'd like to repro the default behavior (which is already there if you don't  set 'gearvr.HandleBackButton' in 1) - yes. If you'd like to add custom logic then all what you need is to handle "Android Back" button.

Interestingly enough, UE4 4.11pre8 doesn't have such console cmd :/

I followed this tutorial to the tee https://docs.unrealengine.com/latest/INT/Platforms/GearVR/GlobalMenu/index.html and on the device, if I do short press, I get "Do you want to exit to Oculus Home?". If I press No, I go into Universal menu instead of my game o.O

If I do long press, I go into Universal menu from which I can't go back into the game.

Alright, I added that cmd - with cmd set to 0, back button doesn't work at all. With cmd set to 1 it works, but I am still getting exactly the same issue as when I didn't have that cmd on eventBeginPlay.

Here is how it looks like in the level BP:


Here is my BP for back button, taken straight from the Epic's docs:

Interesting thing - the app doesn't crash. If I use Back button and go into UM, and then into Oculus Home, I can simply remove phone from GVR, press that button to the left of phone's Home button, select my app that is still running and I will be asked to put phone into GVR. Once I do that, I am back in the game.

@artyom17: I am going to PM you a link to my project. Maybe it would be easier to determine whether I am doing something wrong (and what in particular) or UE4 still has a bug.

I am blaming Epic's outdated docs :blush: 

P.S. If I press K in the Editor when playing, progress bar appears as I hold K key.

Finally got it working !!!

Now I have another question: https://answers.unrealengine.com/questions/396823/gear-vr-how-to-shut-down-app-on-exit-to-the-store.html

Is it a bug or standard behavior?
