Friends I have a problem. I created a working application on Unity with Vuforia. Many times tested on the computer and on the phone. But when it became necessary to sign the application for release in GooglePly. And I did it. The application stopped working on the phone. All I see is the initial screen, standard for Units. And then the black screen.
The question is: what could have happened after the signature of the application, that it stopped working? And how to fix it?
The application is simple, I only use image target and ARCamera.
Please, help me.
