Many people on the Internet say that this should be made optional, otherwise the pop-up window will automatically pop up if arcore is not installed. However, if it is turned off, the pop-up window will not pop up, but the code for detecting the device will not be executed perfectly. If the device is installed Arcore is okay, but it cannot be detected if it is not installed.
If you don’t want to have a pop-up window, you can actually modify the coroutine when it is time to detect it. Yield return ARSession.Install();
In addition, the mono packaging method is not supported because it will crash. For some reasons, mono must be used, so I have to think of another way.
