Crash on startup when tapping compulsively

Hi,

I have checked this happens on several android devices. My engine version is based on 4.6.0 and supports googleplay services

Steps to reproduce the issue:

  • deploy a game to android device

  • start clicking on the middle of the screen
    Then suddenly the game crashes. I have spoted this on the android logs:

    01-17 00:57:06.541: D/UE4(26160): EGL_KHR_image EGL_KHR_image_base EGL_KHR_image_pixmap EGL_KHR_gl_texture_2D_image EGL_KHR_gl_texture_cubemap_image EGL_KHR_gl_renderbuffer_image EGL_KHR_reusable_sync EGL_KHR_fence_sync EGL_EXT_create_context_robustness EGL_ANDROID_image_native_buffer
    01-17 00:57:06.591: D/UE4(26160): Assertion failed: IsInGameThread() [File:F:\UnrealEngine\Engine\Source\Runtime\OpenGLDrv\Private\Android\AndroidEGL.cpp] [Line: 663]

Hey Dredok,

Thank you for reporting this issue. I have attempted a quick repro of this issue and have been unsuccessful. What device would you be using to deploy your project to? Also, would your version of 4.6.0 be a binary version of UE4 or a source build?

Any additional information would be greatly appreciated.

Thanks and have a great day!

this is a source build.

My game uses google play services (not sure if this should affect).

I have reproduced in two android devices:

  • Samsung galaxy s3
  • Aquaris BQ HD

Howdy Dredok,

I have just setup a quick repro (Using Tappy Chicken and enabling Google play) and have not been able to reproduce a crash. Would you be able to share your project with me so that I may attempt a repro of this internally? You can send it to me privately through the forums here: https://forums.unrealengine.com/member.php?4890-Sean-Gribbin

Thanks!

Dear Sean,

Actually I have tested with Tappy Chicken and I have reproduced it!
Just click on Tappy Chicken icon and, before anything is launched, start clicking compulsively in the center of the screen. The game crashes.

I have reproduced it on Samsung Galaxy S3 just 1 minute ago

Hey Dredok,

I am still unable to reproduce this issue internally. Would you be able to attach your DXdiag, build log files, and your monitor logs so that I can create a bug report for this issue?

Any additional information would be greatly appreciated.

Thanks!

Hi Sean,
I really do not understand why in earth you would need a DXDiag and build log files for this. DXDiag? this is an issue related to an android device!

BTW I think you can close this one because I found this:
4.6.1 Hotfix is Live!
Have a look at the fixes available with 4.6.1!

Hey Dredok,

Glad to hear that you have found the a resolution to the issue. The reason I ask for the DXdiag is due to the Report needing and Environment in which the project was created. Since I was unable to recreate the issue internally, I was asking for yours in order to fill that section of the report.

Please let me know if you have anymore questions.

Thanks and have a great day!
