Hi,
It seems that the Android Back input node (blueprint) doesn’t work for me.
I’m using UE 4.5.1 and i’m debuging on Sony Xperia Z1.
Can i catch the back button inputs in some other ways ?
Reguards,
Howdy dremecker,
Thank you for reporting this issue. I have started to dive into this issue and think I may have found the issue that may help you with your setup. Here are a couple of photos of my Setup:
Level Blueprint:
New Interface:
New Game Mode:
New Enum Created:
Just a couple of notes that may help: You are creating a new game mode so be sure to change the Game mode in the world setting to what you have titled the new Game Mode. Once this is done, Be sure that the game mode under the Blueprints dropdown in the Toolbar is also changed to the new GameMode. If it has not, be sure to change it. The Enum selected for the New interface for the Trigger Log Level is the New Enum that has been created.
Let me know if this helps with your issue.
Thanks!
Hello,
Thank you for your reply but the problem didn’t comes from AddLog “BPI-Fonction”, i use it in many other blueprints the way you do without any problem. However, your answer put me on the right way !
I doesn’t use Level blueprint at all, i prefer to devide éléments (and scripts) into différents blueprints and with the touch events routine i forgot that inputs (touch, clic, keyboard, etc.) MUST BE enabled in blueprints when you want to use it.
So, the solution is to enable inputs when you want user to be able to press back button, as you can see below.
It’s a novice mistake, sorry for the trouble.
Hope this will help others scatterbrains like me 
Thank you.
