I am building 1 AR scene with 17 target images. I did not have any errors when building but when I open the apk in the phone the screen is just black (the unity logo didn’t even appear) for few seconds and will closed automatically. I have another file with the same setting (just different content) and have no problem opening it. Can someone please tell me what is wrong?
You may need to play around with the player settings. I had this error too and in my case i needed to use the right target architecture for my smartphone. You can find the target architecture in the player settings
