Black Screen Samsung

October 2, 2020 - 10:15am #1

Hi,

We have a live version of our app and it works perfectly on all devices except Samsung where on initial install it seems to work fine but after a few continuous hours of play with AR when the APP is started again it gets stuck at Black Screen.

As an initial tryouts, we tried re-installing, clearing caches, etc but no solution there.

On checking it on an affected device, in LogCat got the following error for Vuforia.

 

10-02 14:28:18.475: E/Unity(22839): The Vuforia Developer Agreement needs to be accepted before using Vuforia in an application.

10-02 14:28:18.626: I/Unity(22839): File successfully saved at: /storage/emulated/0/Android/data/***appname***/files/Vuforia/CountryPieces.dat

10-02 14:28:18.656: I/Unity(22839): Loading Vuforia Scene...

 

We are Vuforia 8.1.10.

We are in soft launch mode currently but are going to go full throttle in a months time. Can we get some suggestion on how about solving this issue ?

 

Thanks.

Hi,

This is a kown issue when working with OBB files. With 8.6 we introduced a warning for developers in which we mention that the OBB files need to be available before Vuforia is initialized.

Would this be the use-case for you?

Thank you.

Was hoping for some response from the support team or even a direction that we can take to fix this problem.
