Hello! I am running into a very frustrating problem in a Unity C# Project of mine.
I am trying to make a script that will send a notification to android and iOS devices. However, I have noticed that putting both systems into one script may not work properly…
Here’s the problem:
using Unity.Notifications.iOS;
using Unity.Notifications.Android;
This piece of code ends up clashing with itself, because I would assume iOS devices can’t use “Unity.Notifications.Android”. So, I looked up a solution, and I found this:
#if UNITY_IOS
using Unity.Notifications.iOS;
#elif UNITY_ANDROID
using Unity.Notifications.Android;
#endif
This seemed to work for other people, so I tried it out. But, for some reason, it is not functioning like it would in the example. (See screenshot.)
I noticed that the iOS section is not grayed-out. I just brushed it off and continued though. But, errors started showing up all over my code!
It was acting as if the Unity.Notifications.iOS; didn’t even exist! I thought it may be a problem with the build settings, so I switched over to iOS building, and the errors went away. But then, errors showed up on the other half of my code!
The #if statements at the top were essentially doing nothing, and I have no idea how to fix this issue. Does anybody know the solution, or may have some ideas for why it could be doing this? Thanks!
