After the movie is played the game crashes. This happens with every external UI I use in a mediatek device with android 4.4.2. And this only happens with Unreal Engine 4

Please, see the above link for more information and some log traces.

I have also experienced issues with a Samsung Galaxy S3: First movie play does not work (when appears google signing UI). After this, it works.

Howdy Dredok,

Thank you for reporting this issue. I am going to need a bit more information from you before i begin looking into this issue. Are you able to reproduce this issue on a blank template project? I have attempted to add a startup movie to my project and deploy but I have not been able to any crash when opening the project on the device.

Would you be using a source build of UE4 or a binary build? Are you using the 4,7 version of UE4 or a later build?

Any additional information would be greatly appreciated.

Thanks and have a great day!

Hi Sean Gribbin,
I’m using 4.7.2 unreal engine version. Compiled from source. It also fails with 4.7.0

This is a two-fold bug:
1st) related to all devices: any project with google play services will crash on the first launch (when connecting to google play services, the movie plays in the background and the game crashes)

2st) in any mediatek mt6592 device with android 4.4.2 it crashes always.

I will try later adding a startup movie to Tappy Chicken… for the 1st) issue its needed to have a google play sign-in so it can not be done in a blank project.

Hey Dredok,

Would you be able to clarify the devices that you are testing? Could you also include the model numbers of the devices?

Thanks!

GStar 9000 and BQ Aquaris HD (both mediatek mt6592 and both with android 4.4.2). On these devices the game crashes always.

On other kind of devices (Samsung Galaxy S3 for example) it crashes only on the first sign-in with google play services.

Hey Dredok,

Sorry to get back to you so late. Have you been able to package to these device is previous versions of UE4? We currently do not have any mediatek devices in house to test, but i may be able to find a device similar to yours.

I have tested on the Galaxy s3 and have seen no errors. Would the crash be occurring when Google is syncing or after it is done syncing to the device?

Thanks!
