Bug Cannot build for Android

Using Unity 2021.2.7 and I can't build my project to Android. I'm also using PlayFab and Facebook SDK.
I also can't build it on Unity 2021.1.27f1.

Code (csharp):

I sent a bug report with my entire project. 1391435

I found the reason and I was able to fix it (by disabling this function). This code for some reason was causing the build failure. It seems some kind of bug when converting it with IL2CPP.

Code (csharp):

1.  
2.         void MakeVertices()
3.         {                                                         //        2_____1
4.             vertices[0] = CardinalToVertex(0); // [-]    /     \
5.             vertices[1] = CardinalToVertex(1); // [/]   /       \
6.             vertices[2] = CardinalToVertex(2); // [\]  3    #    0
7.             vertices[3] = CardinalToVertex(3); // [-]   \       /
8.             vertices[4] = CardinalToVertex(4); // [/]    \_____/
9.             vertices[5] = CardinalToVertex(5); // [\]    4     5
10.         }
11.  

It's a simple code, it does not make sense. Here are some more functions needed by this code :

Code (csharp):

1.  
2.         ///<summary>Maps cardinal direction to direction hex to vertex.</summary>
3.         Vector3 CardinalToHex(int d)
4.         {
5.             Vector4 result;
6.             switch (d)
7.             {
8.                 case 0: result = new Vector4(1, 0, -1); break;
9.                 case 1: result = new Vector4(0, 1, -1); break;
10.                 case 2: result = new Vector4(-1, 1, 0); break;
11.                 case 3: result = new Vector4(-1, 0, 1); break;
12.                 case 4: result = new Vector4(0, -1, 1); break;
13.                 case 5: result = new Vector4(1, -1, 0); break;
14.                 default: throw new ArgumentOutOfRangeException();
15.             }
16.             var hex = Grid.CubicToWorld(result) - Grid.CubicToWorld(Vector4.zero);
17.             return hex;
18.         }
19.  

Well... I sent the full project. The bug happens on all recent Unity Versions.

 

I am using Unity 2021.2.9f1 and I am getting the same errors trying to build to Android. I can build to Android using Mono instead of IL2CPP. If there are any updates on how to fix this, please post in this thread!

 

It seems that still not fixed, but a fix is coming.

Unity Issue Tracker - [IL2CPP] &quot;BuildFailedException&quot; and Bee errors are thrown in the Console window when building project for Android (unity3d.com)
