I don’t know why this below happens in android.
There is no clue I can get more.
No problem in Editor and PC standalone. It just happens in android.

Howdy Varioov,

Thank you for reporting your issue. I am going to need a bit more information from you so that I may further investigate what you are seeing.

  • Can you Share your Dxdiag and your project log files?
  • Would you be able to provide any reproduction steps as to how i may be able to see this error on my end.
  • What device are you currently attempting to deploy to and what version is that device on?
  • Have you been able to deploy to a mobile device previous to this project?
  • What version of UE4 are you currently running off of?
  • Any additional information would be greatly appreciated.

Thanks and have a great day!

sharing dxdiag and log file.

able to provide any reproduction steps.

  • Unfortunately I don’t know. If I know, I can simply go around it.

device attempting to deploy on

  • galaxy s3 and more, I tried on various mobiles, but failed.

been able to deploy to a mobile?

  • Yes, I did on various mobiles without critical problems except for UAT launch failure error. So I’m not using launch button on menu, I don’t know why it happens too.
  • Anyway, It worked well without any problems on various mobiles.
  • But I don’t know, what exactly makes this problem, but as you can see, the log tells us paper2d has a problem.

version of UE4.

  • 4.4.3

I found why this happened, I moved the code lines from OnConstructor to BeginEvent, but the question is that why this problem only happens in android.
Anyway, You don’t need to look into it in detail.
